EXECUTIVE SUMMARY

As part of Umgeni Water’s commitment to environmental sustainability, Nagle Dam

(including the water surface, shoreline and remaining surrounding property) must be

managed and utilised in an environmentally sound and equitable manner.

Umgeni Water embarked on a process to develop a Resource Management Plan (RMP) for

Nagle Dam, which is the first RMP to be developed for any of the dams owned by this

organisation. Nemai Consulting (RMP Process Facilitator) was appointed by Umgeni Water

(RMP Process Initiator) to compile the RMP for Nagle Dam.

The phases of the RMP development process for Nagle Dam are presented in the diagram

to follow.

This document presents the RMP, which is the culmination of the overall process, and

integrates the information contained in the other deliverables to develop a sustainable plan

for the use and management of Nagle Dam.

An overview of the dam, its operational requirements, infrastructure components and

facilities is provided. The main pieces of environmental and development-related legislation

governing the use and management of Nagle Dam and the surrounding land are also

presented, together with the management functions of key Government Departments.

The RMP also includes a brief description of the following, based on information extracted

from the preceding deliverables:

Biophysical and socio-economic environment, as detailed in the Research Report;

Hindrances associated with the potential utilisation of the dam and its shoreline area for

recreational purposes, based on the findings of the Encumbrance Survey; and

Desired state and objectives for the future management of Nagle Dam, as established as

part of the Vision and Objectives Report.

This information set the scene for the future management requirements for Nagle Dam,

which are provided in the following sections of the RMP:

An Institutional Plan, which consists of a three-tiered management system that includes

a RMP Steering Committee, Operational Management Committee and Dam

Management Committee;

A Zonal Plan, which considered –

The water surface of the Dam;

The shoreline area, which includes the remainder of the Nagle Dam property;

A Strategic Plan, which takes into consideration the management objectives related to

Nagle Dam, based on the outcomes of the RMP deliverables; and

A Financial Plan, which provides information on how revenue generated through

recreational use should be used, as applicable.

Based on the priority management requirements identified for Nagle Dam, various Business

Plans will be developed which will be captured in the final RMP deliverable. The Business

Plans will summarise the operational and financial objectives of the RMP and will contain the

interventions, resources and timeframes required to achieve these objectives.

This RMP will be reviewed every 5 years and revised as necessary, according to changing

priorities, constraints and achievements. The Business Plans will be updated annually.

Nagle Dam

1 INTRODUCTION

1.1 Background

In accordance with section 29 of the Water

Services Act (Act No. 108 of 1997),

Umgeni Water is a water board which

provides bulk potable water and bulk

sanitation services to other water services

institutions in its service area.

As part of Umgeni Water’s commitment to

environmental sustainability, Nagle Dam

(including the water surface, shoreline and

remaining surrounding property owned by

Umgeni Water) must be managed and

utilised in an environmentally sound and

equitable manner. Umgeni Water thus

embarked on a process to develop a

Resource Management Plan (RMP) for

Nagle Dam, which is the first RMP to be

developed for any of the dams owned by

this organisation. Nemai Consulting (RMP

Process Facilitator) was appointed by

Umgeni Water (RMP Process Initiator) to

compile the RMP for Nagle Dam.

1.2 What is an RMP?

According to the Guidelines for the

Compilation of a RMP (DWAF, 2006), the

main aim of this plan is to “attain the

objectives underlying sustainability and to

compile workable, functional sustainable

access and utilisation plans for water

resources and in particular State Dams”. A

RMP is thus a planning tool

aimed at working within the

requirements of existing

Government policy, while

taking into account the needs

and interests of stakeholders.

A RMP can also be explained

as a systematic process for

the sustainable development

and management of a water

resource in the context of


November 2016 2

social, economic and environmental

objectives. In many ways, it shares

similarities with Integrated Water

Resource Management (IWRM). Hence,

one of the main functions of the RMP

process is to develop an Institutional

Plan for the effective management of

State Dams. The focus on institutional

arrangements is accompanied by a Zonal

Plan together with a detailed Strategic

Plan. In addition, a Financial Plan

provides guidance on funding

requirements and funding options.

The National Water Resource

Infrastructure Branch (NWRIB) of the

Department of Water and Sanitation

(DWS) checks that RMPs are compiled in

a procedurally correct manner, in

accordance with the RMP Guidelines

(2006), and that they meet the requisite

statutory requirements in terms of the

National Water Act (Act No. 36 of 1998)

(NWA).

1.3 RMP Triggers for Nagle Dam

There are a number of considerations that

prompted the development of the Nagle

Dam RMP, which include the following

(Umgeni Water, 2016a):

Nagle Dam is a regionally significant

resource and a critical component of

the Mgeni System which supplies

potable water to the eThekwini

Metropolitan Municipality, part of the

economic hub of KZN. The primary

function of the Nagle Dam is thus

water supply, which should not be

jeopardised.

A key constraint that needs to be

taken into consideration for possible

future use and development is the

relatively small water surface area of

the Dam.

Development proposals, some of

which have been in conflict with the

legally adopted spatial plans for the

area, have been received for the

shoreline and the peninsula commonly

referred to as the “island” at the Dam.

Future development pressures may

also arise, due to the waterbody and

surrounding area’s inherent

recreational values.

While the existing Framework for

Evaluating Development Proposals

around Umgeni Water Operated Dams

is currently used to guide decisions

regarding development proposals, a

gazetted RMP that allows some

community and economic

opportunities but safeguards the

primary objective of Nagle Dam, is

recommended to be developed with

the resultant necessary institutional

arrangements to ensure

implementation. The aforementioned

framework is thus an interim measure

until RMPs can be developed and

gazetted for all the dams Umgeni

Water operates. The intention of

Umgeni Water is that once RMPs have

been developed for all the dams

Umgeni Water operates, the

framework will no longer be used as

there will be a legal tool in place.


November 2016 3

From a water quality risk perspective,

any proposed development which

would be likely to increase the

eutrophication, pathogen or turbidity

risks to the dam, with a resultant

negative impact on raw water

treatability and treatment costs, would

be of concern.

Since Umgeni Water does not have

direct control over catchment activities

that can impact raw water quality and

water treatment costs, it is

recommended that Umgeni Water

maintains control over activities within

the Nagle Dam boundary to minimise

the cumulative effective of nutrient and

pathogen inputs to the Dam.

The Nagle Dam property is

surrounded by traditional land and

livestock watering occurs at and

downstream of the dam. Some of the

community use raw water directly from

the Nagle Aqueducts for some

domestic purposes. Further, the

Mkhizwana Water Treatment Plant

(WTP) and eMaphephetheni WTP

abstract raw water from the Nagle

Aqueducts. These two WTPs do not

have the capacity or the same

advanced water treatment capability of

Durban Heights WTP to cope with

water quality incidents. The location of

Nagle Dam together with the size of

Nagle Dam means that there are direct

water quality impacts locally and

therefore the land use management on

the Nagle Dam property is important

for public health.

Through the development of the Nagle

Dam RMP, Umgeni Water would like

to avoid potential conflict between

users, by allowing community and

economic opportunities within the Dam

basin which do not compromise the

primary function of Nagle Dam.

Whilst Msinsi has Reserve

Management Plans in place for those

dams at which they are located, Msinsi

does not manage the entire dam

property (e.g. the area around the dam

wall), which is the case at Nagle Dam.

This means that whilst for the areas

that Msinsi manages, the desired land

uses have been identified; those areas

used for operational areas are not

demarcated on a plan showing all the

uses (existing and desired) on the dam

property. Further, whilst the dam

properties are aligned with the legal

spatial planning tools viz. the

Integrated Development Plan (IDP),

the Spatial Development Framework

(SDF) (both district and local), the

scheme (where they are in place) and

the Strategic Environmental

Management Plan (SEMP), a legal

tool is still required for the land use

management within the Dam property.

Hence the identification of the RMP.

Dam safety, with particular reference

to the uniqueness of the design of

Nagle Dam, is a limiting factor in

allowing recreational opportunities.

The RMP process will explore and

evaluate opportunities that may

harness the potential for utilising the

dam for recreational and economic

reasons, against core principles

underlying efficiency, sustainability

and equity.


November 2016 4

It is noted that Msinsi explores the

recreational and economic potential of

the dam. Due to the organisational life-

cycles of Umgeni Water and Msinsi,

the identified opportunities have not all

been implemented and the RMP will

attempt to provide an assessment of

all the identified opportunities. These

opportunities for the use of the Dam

need to be investigated through a

formal process in light of the various

encumbrances that may hinder such

use, as well as dam safety

requirements.

Through the provisions of the RMP,

the rights of the surrounding

community need to be safeguarded

whilst promoting stewardship for the

dam and state-owned land. This

endeavour will strive to build on the

existing collaborative stewardship that

Msinsi has established and maintained

with the communities in surrounding

traditional areas.

In terms of national priorities and the

associated endeavours of government, the

following triggers were identified for the

Nagle Dam RMP:

1. Protection of water resource

2. Protection of ecosystem goods and

services

3. Sustainable use of waterbody and

surrounding land

4. Unlocking socio-economic potential

5. Equitable access

It is noted that the above triggers were

formally accepted and adopted by the

Project Steering Committee (PSC) during

the inaugural PSC meeting that was held

on 28 July 2015. These triggers are not

necessarily in conflict with those identified

by Umgeni Water but serve to ensure

consistency with the motives for initiating

other RMPs for state dams and provide

alignment within the related overarching

principles.

1.4 RMP Process & Deliverables

The phases of the RMP development

process for Nagle Dam are shown in

Figure 1: Phases of the RMP Development Process for Nagle Dam

1.5 Assumptions, Gaps and

Limitations

The demarcation of the various zones

as part of the Zonal Plans was based

on the extent of the watercourses

(uMngeni River and Nagle Dam)

reflected in the latest aerial

photography received from Umgeni

Water. Going forward, these zones

need to be updated as follows:

The Surface Water Zonal Plan

needs to be based on the Full

Supply Level (FSL) of the Dam,

once confirmed, and

The Shoreline Zonal Plan needs to

be based on the 1:100 year

floodline or delineated riparian

zone (both to be determined),

whichever is greatest (as relevant).

A conservative approach was adopted

to demarcating the zones in the Zonal

Plans, in terms of ensuring the safety

of visitors, safeguarding infrastructure

and facilities at the Dam, as well as

protecting sensitive environmental

features.

SURROUNDING ENVIRONMENT

November 2016 7

2 OVERVIEW OF NAGLE DAM

2.1 Integrated Mgeni Water

Supply System

The Mgeni System in KwaZulu-Natal

(KZN) supplies water to approximately five

million people, as well as the industrial

sectors in the Durban and

Pietermaritzburg regions, the economic

hubs of the province. As shown in Figure

2, the Integrated Mgeni Water Supply

System (WSS) comprises the Midmar,

Albert Falls, Nagle and Inanda Dams, as

well as Mearns Weir and Spring Grove

Dam (commissioned in 2013).

Figure 2: Schematic of Integrated Mgeni WSS

Water is released from Albert Falls Dam to

Nagle Dam from where it is supplied from

two abstraction off-takes under gravity to

Durban Heights WTP. In addition, water

from Nagle Dam is also treated at

eMaphephetheni WTP (owned by Umgeni


November 2016 8

Water) and Mkhizwana WTP (owned by

eThekwini Municipality). This water

primarily supplies the northern and central

parts, and to a lesser extent the western

part, of the eThekwini Municipality.

2.2 Nagle Dam

2.2.1 History

To meet increasing demands for water

after World War II, Durban’s engineers

sought a supply from the uMngeni River.

Nagle Dam was the first dam to be built on

the uMngeni River and was officially

opened on 19 April 1950. It served as an

important source of water for the city of

Durban but supply proved inadequate to

meet the ever increasing demand.

The ownership of Nagle Dam was

transferred from the then Durban

Corporation to Umgeni Water in 1983

(Umgeni Water, 2000). The dam was

registered with the then Department of

Water Affairs and Forestry on 26

November 1986 (Umgeni Water, 2015b).

The management of the Nagle Dam and

Game Reserve was transferred to what is

now Msinsi Holdings State Owned

Company (SOC) Limited (hereafter

Msinsi) in 1994 (Msinsi, 2015). Created in

1992 as Msinsi Holdings (Pty) Ltd, the

registration status of Msinsi changed in

April 2015 to that of a State Owned

Company, SOC Ltd (Msinsi, 2015). Msinsi

trades as “Msinsi Resorts & Game

Reserves” (Msinsi, 2015) and is a wholly-

owned subsidiary of Umgeni Water

(Msinsi, 2015).

The 1989 Dam Safety Inspection

“expressed concern about the spillway

capacity of the dam in relation to the

recommended design flood (RDF) and the

safety evaluation flood (SEF)” (Umgeni

Water, 2000). The 1998 dam safety

inspection confirmed the 1989 findings.

The dam safety inspections also identified

problems with the functioning of the

diversion gates in the diversion dam. The

then Department of Water Affairs and

Forestry instructed Umgeni Water “to

increase the spillway capacity of Nagle

Dam to be able discharge the full SEF,

and to refurbish the diversion dam gates”

(Umgeni Water, 2000). The six 6.1m wide

x 9.4m high diversion weir gates were

replaced between 2002 and 2004 (Umgeni

Water, 2015). The 5.8 high concrete mass

gravity diversion isolating structure was

completed in 2002 (Umgeni Water,

2015b). The emergency spillway (fuse

plug) was completed in 2002 (Umgeni

Water, 2015b). The saddle dam was

raised from 12m to 16m in 2002 (Umgeni

Water, 2015b).

The new abstraction point, which releases

water into Aqueducts 3 and 4, was

constructed in 1970 (Mhlophe pers.

comm., 2016).

2.2.2 Location

The impoundment is situated within the

jurisdiction of the uMgungundlovu District

Municipality (DM) and the Mkhambathini

Local Municipality (LM), and is

approximately 25 km east of

Pietermaritzburg (see Figures 3 – 5).


November 2016 9

2.2.3 Ownership

Nagle Dam, including the shoreline and

remaining surrounding property (see

Figures 4 – 5), is owned by Umgeni

Water. In terms of the NWA, DWS

remains the custodian of the water.

2.2.4 Dam Operation

Umgeni Water operates Nagle Dam for

potable water supply. The DWS

management philosophy is to keep as

much water as possible in Midmar (the

highest dam in the system), to use Albert

Falls, via Nagle, to keep Durban supplied,

and to limit the abstractions from Inanda

only to that which cannot reliably be

supplied from higher up (Still et al, 2010).

Depending on the water demand, Nagle

Dam supplies water to Durban Heights

WTP 24 hours a day. Albert Falls Dam

acts as storage for Nagle Dam. When the

Nagle Dam Hydro Power system is

operational and the dam’s level drops

below 80 % additional water releases from

Albert Falls Dam is requested (Mhlophe

pers. comm., 2015).

Nagle Dam was built at the downstream

extremity of a horseshoe bend in the

uMngeni River and an upstream flood

diversion structure was provided with the

diversion channel cut through the

intervening divide. Heavily silt-laden

waters can thus be bypassed downstream

and the dam filled on the recession. Under

normal operating conditions, a 70 NTU

turbidity alert level has been set to warn

Operations of poor water quality flowing

into the dam. At 100 NTU, consideration

is given to diversion of the dam inflow,

dependent on the status of water

resources in the Mgeni System. Under

drought conditions, diversion is not usually

the preferred strategy, and the turbid

water is allowed to flow into the dam, but

is closely monitored.

User zones

According to the Reserve Management

Plan (Msinsi, 2012), the park is divided

into different user zones based on the

locations of the various management

zones, facilities available within each

zone, the objective for each area and the

characteristics of these areas within the

park. The zones are listed in Table 3 and

shown in Figure 9.

Table 3: Nagle Dam Management Units (Msinsi, 2012)

Zone Management Requirements

Wilderness: remote and quiet

Characterized by indigenous flora and fauna, hectares of almost undisturbed environments.

These are priority areas as they keep biological assets like game

There are very limited or no activities at all taking place within wilderness areas

Security of these zones is maintained by regular patrols by field rangers.

Vehicle movement is limited within wilderness areas.

Hunting activities take place once a year within wilderness zones

Low intensity

Low intensity zones have limited visitor activity. They are mainly zoned for tourists’ routes for activities like game drives, excursions and guided trails.

Very limited development takes place within these zones. Pruning of tree branches, cutting of trails and marking of vegetation (tree names) is about the only maintenance taking place.

Only a certain number of visitors can be allowed to access low intensity zones at controlled intervals

High intensity

This is the visitors playground, where all visitors meet for different activities be it accommodation, camp sites, special events, conferencing and picnicking.

There is high movement of controlled vehicles by visitors and staff personnel

The high intensity zone is characterized by a combination of visitor facilities and constant maintenance and minimized development.

2.3 Environmental Governance

2.3.1 Legislative Framework

The RMP forms the overarching

framework for the management of Nagle

Dam. It is informed by relevant policy,

legislation and planning documents

administered by other Government

Departments. Similarly, these

Departments are required to duly consider

the RMP as part of their strategic planning

and decision-making functions.

A RMP is founded in the following key

sections of the NWA:

Section 2 – Purpose of the Act;

Section 3(1)-(3) – Public trusteeship of

nation's water resources;

Section 21(k) – Using water for

recreational purposes;

Section 26(1), (2) and (4) – Draft

Regulations; and

Section 113 – Access to and use of

government waterworks for

recreational purposes.

In addition, the Regulations published

under Government Notice (GN) No. R.

1046 of 30 October 2015 relate to the

access and use of Government

Waterworks and the surrounding state-

owned land for recreational purposes in



November 2016 19

terms of the NWA. They are currently in

draft format and are expected to be

finalised at the end of 2016 (Mzanywa

pers. comm., 2016). The legal status of

approved RMPs will be enabled through

these Regulations once they have been

finalised and signed off by the Minister of

Water and Sanitation.

The main pieces of environmental and

development-related legislation governing

the use and management of Nagle Dam

and the surrounding land are presented in

the table to follow. Note: this list does not

attempt to provide an exhaustive

explanation, but rather an identification of

information from the CIWSP into the

management objectives for the Dam.


November 2016 27

2.4 Biophysical Environment

The information to follow was extracted

from the Nagle Dam RMP Research

Report (Umgeni Water, 2016d). The

reader is referred to the aforementioned

document for more detailed information

(including associated maps) pertaining to

the environmental features that are

succinctly discussed in the sub-sections to

follow.

2.4.1 Climate

According to Msinsi (2012), Nagle’s

temperature is mostly influenced by the

tropical weather conditions of Durban and

therefore relatively warm both summer

and winter. Summer temperatures vary

from 26°C to 40°C with very limited air

flow due to surrounding hills. Winter

temperatures vary from a cold 4°C in the

morning and at night to a hot 27°C during

the day.

Nagle Dam is known for its calm waters.

This can be attributed to the surrounding

topography (low undulating mountains),

which serve to buffer the impoundment.

Dense vegetation in parts of the

surrounding area provides surface friction

that also slows down the movement of air.

2.4.2 Geology & Soils

The geology of Nagle Dam is formed by

the deposition of the Natal group sand

stone which was the first sediments of the

new continent about 490 million years

ago. The geology is mainly Natal group

and Natal metamorphic province granite

(see Figure 10). Most of these were

deposited by the rivers that drained from

the highlands to the northeast. Further to

the south the sediments are finer grained

and forms resistant sand stone cliffs which

give rise to the table top topography as

seen in the Valley of a Thousand Hills in

KZN (Msinsi, 2012).

Figure 10: Simplified geology (Vorster, 2003)



November 2016 28

According to DWAF (2004), soil cover

throughout the area is generally shallow

and is strongly parent-material related due

mainly to the prevailing topographic

conditions. Soils are mainly of sandy types

developed on quartzose rocks, or clayey

soils developed on argillaceous and basic

igneous and metamorphic rocks. Deeper

transported soils are present as colluvium

on lower slopes, with alluvium occurring in

valley bottoms.

2.4.3 Topography

The terrain morphology of the area in

which Nagle Dam is located is dominated

by highly dissected low undulating

mountains. Steep gradients are

encountered along the majority of the

northern shoreline of the dam. The land in

the main reserve contains steep gradients,

which is characteristic of the greater

area’s Valley of a Thousand Hills.

2.4.4 Surface Water

Catchment Overview

Nagle Dam falls within the Pongola-

Mtamvuna WMA, and is situated in the

U20G quaternary catchment (see Figure

11). The dam is also fed from the U20F

quaternary catchment.

Figure 11: Quaternary Catchments that form part of the uMngeni Catchment (main dams shown)


Nagle Dam

Albert Falls Dam

Midmar Dam

Inanda Dam


November 2016 29

Nagle Dam is situated on the slow

perennial flowing uMngeni River. The

confluence of the uMngeni River with the

Mkhabela River is located in the

wilderness area of the Nagle Dam

Property. The Mbhava River flows into the

main stem of the uMngeni River

downstream of the dam. Refer to Figure

12.

Figure 12: Watercourses surrounding Nagle Dam

(Source: South African 1:50000 topographical map vector data)

The uMngeni River system is largely

regulated and developed. The catchment

is serviced by Midmar Dam, Albert Falls

Dam, Nagle Dam and Inanda Dam, as

well as the Mooi-Mgeni transfer scheme.

Nagle Dam has a unique hydrological

regime that is not subject to great

seasonal fluctuations as it receives a

steady input all the year round by water

discharged from Albert Falls Dam for raw

water abstraction for treatment.

The major land cover encountered in the

U20G quaternary catchment includes

thicket and bushland, followed by

commercial sugarcane. Thereafter it is

grassland and forestry, followed by

cultivated land (subsistence, commercial

and grass). Lastly, some residential areas


uMngeni


November 2016 30

(primarily scattered rural settlements) and

degraded land (unimproved grassland) are

also found in the quaternary catchment.

Ecological Integrity

A significant contributor to the reduced

ecological integrity of the river reaches

between Albert Falls Dam and Nagle Dam

is flow regulation. As mentioned, a

continuous base flow is released from

Albert Falls Dam which alters the flow

regime by excluding seasonality.

According to Hunter (pers. comm., 2016),

it should be noted that the river’s width

has increased where possible and due to

constant flow the river’s fluvial

geomorphology has changed to

accommodate this flow. In addition, the

Mpolweni and Cramond Rivers flow into

the uMngeni River well upstream and near

Albert Falls, which contribute not only to

the sediment load but also increase flow at

times of flooding in the main stem (Hunter

pers. comm., 2016).

Nagle Dam also affects the flow regime in

the downstream aquatic environment.

Poor water quality and impacts to the

riparian and instream habitats also

deteriorate the ecological state of the river.

The Chief Directorate: Resource Directed

Measures of DWS initiated a study during

2012 to undertake the Comprehensive

Reserve, classify all significant water

resources and determine the Resource

Quality Objectives (RQOs) in the then

Mvoti to Umzimkulu WMA. An Ecological

Water Requirements (EWR) site (see

Figure 13) was selected as part of the

Reserve Determination. The summarised

EcoClassification results for this site

(Mg_I_EWR5) are as follows:

Ecological Importance and Sensitivity

(EIS): MODERATE -

Highest scoring metrics were

diversity of habitat types and

features, taxon richness and rare

and endangered riparian species.

Present Ecological State (PES): D -

Decreased baseflows and floods

due to upstream dams and general

land use in the upper catchment;

Reduced habitat abundance;

Deteriorated water quality;

Alien invasive vegetation species,

vegetation removal and sand


November 2016 31

mining leading to a general loss of

connectivity and bank modification;

Presence of two predatory alien

fish species in the reach.

Figure 13: EWR site below Nagle Dam

Recommended Ecological Category

(REC): D -

EIS was Moderate and the REC

was therefore set to maintain the

PES.

It should be noted that Mg_I_EWR5 is

located downstream of the confluence of

the Msunduzi River with the uMngeni

River, and that the former river

fundamentally changes the water quality in

the mainstem.

River Freshwater Ecosystem Priority

Areas (FEPAs) include the Mpolweni River

(U20F quaternary catchment) and

Mkhabela River (U20G quaternary

catchment). A Fish Support Area and Fish

Corridor also occur on the Sterkspruit

(U20F quaternary catchment). The

management of the FEPA River and the

associated sub-catchments in accordance

with their intended objectives will

contribute towards improving water quality

and aquatic biodiversity in Nagle Dam.

Aquatic Alien Invasive Species

Although aquatic alien invasive plant

species are not a current problem at Nagle

Dam, the potential spread or proliferation

of such species is a potential risk. Species

that pose a threat in the Nagle Dam

Catchment include:

Pistia stratiotes (Water Lettuce);

Nagle Dam

uMngeni River

Msunduzi River


November 2016 32

Eichhornia crassipes (Water

Hyacinth); and

Salvinia molesta (Kariba Weed).

A multi-stakeholder working group, which

promotes the eradication of alien aquatic

weeds by the use of biocontrol agent,

herbicides and manual removal, is active

in the catchment.

Water Quality

The relevance of the subuser groups

associated with recreational use (inked to

water quality) in terms of Nagle Dam is as

follows:

Full contact recreation - Although

swimming at Nagle Dam is prohibited,

the surrounding community may

informally use the basin for full contact

(swimming or bathing);

Intermediate-contact recreation -

Canoeing and angling are the most

popular recreational activities at the

dam; and

Non-contact recreation - The

accommodation facilities and non-

contact recreational activities at Nagle

Dam rely on the aesthetic qualities of

the waterbody.

Umgeni Water undertakes water quality

monitoring at Nagle Dam at the following

points (see Figure 14):

1. DNG004 - Nagle Main Basin

Integrated (near dam wall);

2. DNG037 - Nagle New Abstraction

Integrated;

3. RMG015 - uMngeni Nagle Dam Inflow;

and

4. RMG016 - uMngeni downstream of

Nagle Dam.

Figure 14: Water quality monitoring points DNG004 and DNG037


November 2016 33

Potential sources of water quality impacts

upstream of Nagle Dam include:

Agricultural activities (nutrients,

biocides and other pollutants);

Animal feedlots, abattoirs and

crocodile farms (nutrients and

pathogens);

Timber plantations (harvested related

erosion, nutrient release, alien weed

invasion and poor river channel

management);

Waste disposal sites;

Waste Water Treatment Works

effluent and sewage discharges

(nutrients and pathogens); and

Human settlements (land clearing and

overgrazing which increase turbidity,

nutrients and pathogens).

A Water Quality Assessment was

undertaken as part of the RMP, which

evaluated the fitness of the water for

recreational use over time, as well as the

present trophic status of the dam. The

temporal analysis and comparison of the

water quality at two monitoring points

(Nagle Main Basin Integrated and Nagle

New Abstraction Integrated) within Nagle

Dam indicate that:

The Dam is likely to be in a stable

oligotrophic state, with a mostly

moderate nuisance of algal bloom

activity, and a moderate potential for

algal and plant productivity;

Nagle Dam can be considered suitable

for full, intermediate and non-contact

recreational use in general, however,

rare water quality conditions do occur

that make it unsuitable for uses and

In the event of an algal bloom, suitable

control and management actions need

to be implemented (as applicable).

Biomonitoring

Umgeni Water conducts biomonitoring by

employing the South African Scoring

System 5 (SASS 5) tool to assess the river

health at the following sampling points:

1. RMG013 - weir upstream of Dam; and

2. RMG016 - uMgeni downstream of

Dam.

Biomonitoring results at these sampling

points are presented in Figure 15.

Figure 15: SASS 5 data compared for RMG013 and RMG016


November 2016 34

In most cases, the SASS 5 scores,

referred to as Biotic Integrity (BI), were

lower at the downstream sampling point

compared to the results at the upstream

point (for the period March 2011 to

December 2014). The results could reflect

better habitat conditions at the upstream

point, or could relate to the water quality at

the two sites. Insufficient data is available

to draw further conclusions in this regard.

2.4.5 SEA & SEMP

The uMgungundlovu DM undertook a SEA

and developed a SEMP, which serves as

a pro-active tool that will guide decision-

making within the district from an

environmental management perspective

(uMgungundlovu District Municipality,

2012). According to the SEA, Nagle Dam

is identified as a water quality

environmental control zone (ECZ) which is

spatially defined as a one kilometre buffer

of the dam upstream of the dam wall, with

associated control measures.

2.4.6 Flora

Biomes & Vegetation Types

Scott-Shaw and Escott (2011) described

the study area as falling within the

Grassland and Savanna Biomes. The

vegetation types on the property coincide

with the biomes and include Dry Coast

Hinterland Grassland and Eastern Valley

Bushveld (see Figure 16).

Figure 16: Vegetation types

The following threatened terrestrial

ecosystems occur at the Nagle Dam

property:

Ngongoni Veld (Vulnerable) -

wilderness area and section of the

property cut off by the P26;



November 2016 35

Umgeni Valley Bushveld (Endangered)

– mostly along northern boundary of

the property; and

New Hanover Plateau (Critically

Endangered) – mostly along eastern

and southern boundary of the

property, as well as on the peninsula.

The Environmental Impact Report

compiled by SRK Consulting (2000) for

the Nagle Dam Spillway Betterment

included the following observations in

terms of the vegetation on the property:

Most of the area around the dam has

been disturbed to different degrees;

The picnic site and the around Msinsi’s

and Umgeni Water’s infrastructure and

the hatchery is mostly grassland with

patches of exotic and indigenous

trees;

The natural neck to the peninsula is

mainly savanna, with an area of closed

canopy woodland on the left hand

abutment of the main dam wall;

The area to the east of the saddle

embankment comprises dense,

wooded savanna;

Vegetation on the slopes north of the

river, below the dam wall and the

alluvial bottom of the river valley

comprises mostly woodland, with

patches of open savanna and

grassland;

The woodland below the main dam

wall is a disturbance feature, however,

because the flow in the river from the

main dam itself has diminished (most

downstream flow comes from the

diversion channel which enters the

river course about 500m downstream

of the main dam wall), leaving a river

bed in which vegetation has

established itself. In the event of a

major flood, much of this vegetation

would be destroyed; and

Almost all areas of the reserve have

dense infestations of invasive exostic

species, notably Lantana (Lantana

camara), Chromolaena (Chromolaena

odorata) and Bugweed (Solanum

mauritanum), which form an

impenetrable understorey. Msinsi

implements a terrestrial alien plant

eradication programme which aims to

restore the vegetation on the

peninsula and the western parts of the

reserve to its natural state.

Refer to the RMP Research Report for the

lists of flora species recorded in the Nagle

Dam reserve as well as surrounding

region.


November 2016 36

2.4.7 Fauna

General observations with regards to

fauna at Nagle Dam follow:

Mammals -

Oribi (Ourebia ourebi), Blue Duiker

(Philantomba monticola), Side-

striped Jackal (Canis adustus) and

Common Dasymys (Dasymys

incomtus) were mammal species

of conservation importance known

to occur in the region.

Some of the animals that

historically occurred in the area

were reintroduced to maximize the

biodiversity value of the park

(Msinsi, 2012). Large mammals in

the reserve include Giraffe (Giraffa

camelopardalis), Impala

(Aepyceros melampus), Kudu

(Tragelaphus strepsiceros), Zebra

(Equus burchelli), Nyala

(Tragelaphus angasii), Blue

Wildebeest (Connochaetes

taurinus), Warthog (Phacochoerus

africanus) and Grey Duiker

(Sylvicapra grimmia).

Avifauna -

According to SRK Consulting

(2000), the savanna, open and

closed woodland, as well as

riverine and dam aquatic

ecosystems provide a diversity of

habitats for a large number of bird

species.

There are no Important Bird &

Biodiversity Areas near Nagle

Dam.

Herpetofauna (Reptiles and

Amphibians) -

Large-scaled Grass Lizard

(Chamaesaura macrolepis) is the

reptile species of conservation

importance known to occur in the

region (grid cell).

Only one Red data frog species is

known to occur in the region

namely Spotted Shovel-nosed

Frog (Hemisus guttatus).

African Rock Pythons (Python

sebae) are also commonly seen on

the property by the Msinsi staff.

Fish -

According to SRK Consulting

(2000), several introduced and

indigenous fish live in Nagle Dam,

including Scaly Yellowfish (Barbus

natalensis) and Wide-mouthed

Bass (Micropterus salmoides).


November 2016 37

Refer to the RMP Research Report for the

lists of fauna species recorded in the

Nagle Dam reserve as well as surrounding

region.

2.4.8 Critical Biodiversity Areas

According to EKZNW (2014), a Critical

Biodiversity Area (CBA) means natural or

near-natural features, habitats or

landscapes (terrestrial, aquatic and

marine) that are considered critical for (i)

meeting national and provincial

biodiversity targets and thresholds (ii)

safeguarding areas required to ensure the

persistence and functioning of species and

ecosystems, including the delivery of

ecosystem services; and/or (iii) conserving

important locations for biodiversity

features or rare species.

CBAs in relation to the Nagle Dam

property are shown in Figure 17. CBA:

Irreplaceable Areas mostly coincide with

threatened terrestrial ecosystems. CBA:

Optimal Areas include portions of the

wilderness area and the area cut off by the

P26, as well as pockets of land to the

north of the uMngeni River.

Figure 17: CBAs

2.4.9 Protected Areas

Msinsi manages the the Nagle Dam

Reserve in a manner that enhances

biodiversity values while at the same time

providing access for recreation to the

public (Msinsi, 2012). The wilderness area

in particular has a conservation focus.

Although the reserve does not have any

formal protection status in terms of

NEM:PAA, Msinsi may want to pursue

declaring it as a protected area. This will

impose management obligations to ensure

that this status is achieved and

maintained.




November 2016 38

2.4.10 Historical and Cultural Features

Various infrastructure associated with

Nagle Dam is older than 60 years and is

afforded protection through the KZN

Heritage Act (Act No. 04 of 2008).

According to Msinsi (Mhlophe pers.

comm., 2015), a grave yard is located in

the southern side of the dam. The graves

are also protected in terms of the

aforementioned legislation.

There is evidence of artefacts along the

uMngeni River below Table Mountain,

where terraces mark the position of

ancient parts of the river bed (eThembeni

Cultural Heritage, 2011).

According to Msinsi (2012), Nagle Dam is

surrounded by communities that are

deeply rooted in culture, with the Manyavu

Traditional Authority being the dominant in

cultural practices and its people wear

traditional clothing.

2.4.11 Air Quality

Due to the rural nature of the surrounding

area, the air quality is regarded to be

good. Localised impacts to air quality

include burning of fossil fuels, emissions

from vehicles travelling on the surrounding

road network, dust from un-vegetated

areas and dirt roads, smoke (veld fires

and seasonal burning of sugar cane),

agricultural activities, and methane

release from larger livestock. In the

greater area, air quality is influenced by

anthropogenic activities in urbanised

areas such as Pietermaritzburg,

Camperdown and Cato Ridge.

Sensitive receptors to dust and other air

quality impacts in the area include human

settlements and sensitive fauna and flora.

2.4.12 Agricultural Potential

According to the Department of Agriculture

and Rural Development (Mashele pers.

comm., 2015), a considerable portion of

the property is located on high potential

agricultural land (Category B of the KZN

Agricultural Land Categories). Category B:

Threatened is defined as moderate to high

potential agricultural land and has the

potential to be used sustainable, with few

limitations to agricultural production (Collet

and Mitchell, 2012). Category E: Mixed

Agricultural Land is also encountered on

site, which is regarded as land with limited

to no potential for agricultural production.

No formal agricultural activities take place

within the property.


November 2016 39

2.5 Socio-Economic Environment

The information to follow was also

extracted from the Nagle Dam RMP

Research Report (Umgeni Water, 2016d).

2.5.1 Land Use & Land Cover

Nagle Dam is situated in a rural area, with

scattered traditional settlements

surrounding the property. The pattern of

settlement has been influenced by

geographical, biophysical and land tenure

features. Surrounding land uses include

small-scale and subsistence farming and

grazing on Traditional Authority land.

The land cover, based on the South

African National Land Cover Dataset

(2013/2014), is shown in Figure 18. The

majority of the property and greater

surrounding area is characterised by

thicket / dense bush, with pockets of

grassland. Settlements occur around the

property, which includes areas cleared to

make way for dwellings and subsistence

agriculture, and is also due to heavy

grazing and some bush clearing for

firewood.

Figure 18: Land Cover (© GEOTERRAIMAGE - 2014)



November 2016 40

2.5.2 Land Tenure

The Nagle Dam Property (land within

purchase line) belongs to Umgeni Water.

The land surrounding Nagle Dam belongs

to the Ingonyama Trust Board (ITB) and

falls under the following three Traditional

Authorities (see Figure 19):

1. Gcumisa Traditional Authority to the

north and east;

2. Mapumulo Traditional Authority to the

west; and

3. Mdluli / Manyavu Traditional Authority

to the south.

Figure 19: Traditional Authorities

2.5.3 Socio-Economic Profile

The Research Report includes data

pertaining to the socio-economic profile,

based on Census 2011, for the

Mkhambathini LM (Wards 1 and 2) and

the uMshwathi LM (Ward 6). Refer to

Figure 20. The profile of these areas is

similar to what is encountered in many of

the other rural parts of KZN.


November 2016 41

Figure 20: Wards included in socio-economic profile

2.6 Encumbrances

As part of the RMP deliverables, an

Encumbrance Survey (Umgeni Water,

2016b) was conducted to establish

whether there are any hindrances to the

RMP process or limitations associated

with the utilisation of the dam and the

surrounding property for recreational

purposes.

The encumbrances and key management

considerations related to recreational

opportunities at Nagle Dam were

categorised as follows:

Encumbrances identified during Public

Participation -

As part of Public Participation to

date, all stakeholders were asked

to identify strengths, weaknesses,

opportunities and threats (i.e.

SWOT Analysis) for the Dam. The

weaknesses and threats assisted

with the identification of potential

encumbrances.

Biophysical encumbrances -

Water quality -

Various sources of water

quality impacts upstream of

Nagle Dam;



November 2016 42

Poor water quality may pose

health risks to full-contact

recreational users;

The dam’s water quality has a

significant impact on the cost of

treating water;

No documented proof was found

that provision is made in the

operating rule for releasing the

EWR;

Any proposed recreational use

needs to ensure that the spread of

alien plants is prevented and

should not compromise the

existing management efforts at

Nagle Dam;

The presence of alien fish species

causes the displacement of

indigenous competitor species and

leads to predation on indigenous

species;

Large portions of the Nagle Dam

property fall within Critical

Biodiversity Areas;

The Biodiversity Sector Plan

classifies Nagle Dam as an

“ecological support area which

means that it is an area that

supports key biodiversity and

ecological processes such as

water production and corridors in

the landscape”. The land

management objective identified

for this area is to “maintain near-

natural with limited eco-service and

biodiversity loss”;

Animals kept at the Nagle Dam

Game Reserve are at particular

risk of poaching;

A considerable portion of the

property is located on high

potential agricultural land;

Steep gradients are encountered

along the majority of the northern

shoreline of the dam; and

The land in the main reserve

contains steep gradients, which is

characteristic of the greater area’s

Valley of a Thousand Hills.

Historical and cultural encumbrances -

A grave yard is located in the

southern side of the dam; and

Although Table Mountain offers

recreational opportunities, the

mountain is associated with

cultural beliefs and access may be

denied by the Traditional

Authorities;

Encumbrances related to the

management of the property -

According to the Reserve

Management Plan for Nagle Dam

and the Game Reserve (Msinsi,

2012), the park is divided into

different user zones based, which

pose certain restrictions to use and

access;

Encroachment of dwellings into

firebreaks;

There is no recent, comprehensive

survey of the entire property;

Various parts of the property are

not fenced and less actively

managed;

The winding roads, which traverse

rural areas in the Valley of a

Thousand Hills, add travelling time

to the dam;


November 2016 43

The P26 road separates the

property and creates a portion of

land in the central part of the

reserve. As this road cannot be

closed off, activities on the

property need to be managed to

ensure the safety of both road

users and visitors to the dam; and

Uncontrolled access by members

of the community and livestock;

Encumbrances related to the safety of

the dam for users;

Legal encumbrances –

A church was built on the property

outside of the fenced area;

Currently there are no agreements

in place with any recreational clubs

that currently use the dam;

Encumbrances related to existing

recreational use -

The rules need to be updated to

make provision for the permitted

uses and activities that take place;

Vandalism of the canoeing gear

stored in containers at the picnic

area;

There are no shower facilities

available for the canoeists;

Recreational capacity of the dam;

Hunting takes place in the main

reserve. Suitable provision needs

to be made to ensure that the

remainder of the dam is a no gun

zone;

CIWSP will need to be

implemented at Nagle Dam;

Any proposed use must be

compatible or enhance the

recreational activities associated

with these facilities, and must not

compromise the investments

already made;

Nagle Dam has a relative small

surface area and is also located on

a sharp bend in the river, which

may hinder certain types of

recreational use and will reduce

the carrying capacity;

The formal recreational areas at

the 2 picnic sites provide limited

area for recreational activities;

For large events there is

insufficient space to safely

accommodate a large number of

vehicles;

Encumbrances related to services –

The remoteness of the Dam and

the surrounding topography

complicate the supply of services;

and

An increase in septic tanks could

pose a risk of contaminating the

Dam’s water.

Encumbrances related to the operation

of the dam -

In times when higher volumes are

released from Albert Falls Dam, an

artificial rise (not rain induced) in

the upstream water level of the

uMngeni River will occur, which

may pose safety risks to the users;

The configuration of the flood

diversion structure may pose a

safety risk to users within the

downstream reach of the uMngeni

River during a flood event; and

Recommendations from the Fourth

Dam Safety Evaluation of Nagle

Dam need to be taken into

consideration.

MANAGEMENT OBJECTIVES

SECTION


November 2016 45

3 MANAGEMENT OBJECTIVES

Objectives for the future management of Nagle Dam were identified and are documented in

the Vision and Objectives Report (Umgeni Water, 2016c). Amongst others, this exercise

contributed towards understanding the desired use of the dam and the surrounding land on

the property, based on the requirements from Government Departments (e.g. municipal SDF

and LUMS), aspirations of the community members and sustainable management

considerations.

3.1 Vision Statement

The purpose of setting a vision for Nagle Dam is to articulate a collective statement of future

desired use and state for the impoundment and adjoining state land. The vision statement

developed as part of the RMP process is as follows:

To ensure that the quality of the water resource is protected and to unlock the socio-

economic potential in a manner that promotes sustainable and equitable utilisation, while

maintaining a collaborative relationship with surrounding communities.

3.2 Management Objectives

The realisation of the desired state relies on the disaggregation of the vision into

Management Objectives. These objectives are best presented in a hierarchy, which begins

at its coarsest level with the vision and ends in a series of management objectives of

increasing focus, rigour and practical achievability. The high-level objective hierarchies for

Nagle Dam are presented in Figures 21 – 26.

November 2016 49

3.3 Criteria for Use and Management

Criteria are necessary to evaluate and filter the objectives for the future use and

management of Nagle Dam. These criteria will also serve to aid decision-making that is

aligned with the vision for the dam.

The NEMA principles, as well as Local Agenda 21 that gives effect to these principles, set

the framework for ensuring that development embraces sustainability. From the NEMA

principles, the following criteria were developed to support the Nagle Dam vision and to

guide achieving the desired use and state:

Any activities and development must be socially, environmentally and economically

sustainable and must comply with the relevant legislation;

The environmental features that form the fabric of the area’s sense of place, should be

enhanced and preserved;

Manage activities to ensure that pollution and degradation of the environment are

avoided, or, where they cannot be altogether avoided, are minimised and remedied;

The opportunities for tourism should be explored in a sustainable and equitable manner;

Equitable access to and use of the resources and its associated benefits and services;

Negative impacts on the environment and on people’s environmental rights be

anticipated and prevented, and where they cannot be altogether prevented, are

minimised and remedied;

The participation of Interested and Affected Parties (I&APs) in the environmental

governance of the Dam must be promoted;

Decisions must be taken in an open and transparent manner, and access to information

must be provided in accordance with the law;

There must be intergovernmental coordination and harmonisation of policies, legislation

and actions relating to the Dam;

Sensitive, vulnerable or dynamic ecosystems (including the wilderness area) require

specific attention in management and planning procedures;

A risk-averse and cautious approach is applied, which takes into account the limits of

current knowledge about the consequences of decisions and actions;

The social, economic and biophysical impacts of activities, including disadvantages and

benefits, must be considered, assessed and evaluated, and decisions must be

appropriate in the light of such consideration and assessment; and

A high degree of environmental awareness should be encouraged amongst all members

of the community.

INTEGRATED PLANNING,

MANAGEMENT & ZONING


November 2016 51

4 INTEGRATED PLANNING, MANAGEMENT & ZONING

4.1 How does the RMP Work?

The overarching framework for the Nagle Dam RMP is presented in Figure 27. The RMP

consists of four main components, namely the Institutional Plan, Strategic Plan, Zonal Plan

and Financial Plan.

Figure 27: Nagle Dam RMP Framework

In terms of the Institutional Plan (refer to Section 4.2), a three-tiered management system is

proposed which includes a RMP Steering Committee (RSC), Operational Management

Committee (OMC) and Dam Management Committee (DMC).

The Zonal Plan (refer to Section 4.3) considered the following:

Water surface of the Dam; and

Shoreline area (including the remainder of the Nagle Dam property).


November 2016 52

The Strategic Plan (refer to Section 4.5) takes into consideration the management

objectives related to Nagle Dam, based on the outcomes of the preceding RMP deliverables.

This information is then used to produce the Business Plans for each prioritised objective.

The Financial Plan (refer to Section 4.4) generally provides information on how revenue

generated through recreational use should be used, if applicable. This information also

contributes towards the Business Plans.

4.2 Institutional Plan

4.2.1 Overarching Institutional Framework

The Institutional Plan consists of the arrangements and structure for the collective and

coordinated management of Nagle Dam. The Institutional Plan consists of the following

(Figure 28):

A three-tiered management system consisting of the RSC, OMC and DMC;

An open communication forum to share information and allow stakeholders to raise

concerns and ideas regarding the management of the Dam. It also provides a platform

for dealing with issues and challenges faced by users; and

Management tools, which include agreements, affiliations and targets.

Figure 28: Nagle Dam Institutional Framework


November 2016 53

4.2.2 Dam Management Committee

The DMC comprises all parties that have a direct influence on Nagle Dam. The committee,

which will be chaired by Umgeni Water, consists of the representatives shown on Figure 29.

Refer to Section 2.3.2 for a description of the management functions of those key

Government Departments that are represented on the DMC.

The DMC will also include the following specific parties:

Representative from Albert Falls Dam, due to the intricate relationship between these

two impoundments and the operating rules for the overall system, which may influence

recreational activities; and

Representatives from the ITB and each of the three Traditional Authorities (Gcumisa,

Mapumulo and Mdluli / Manyavu) surrounding the property.

Although not relevant at present, authorised access point representatives (i.e. all commercial

operations and recreational clubs with authorised access points) may be identified in the

future and should also form part of the DMC.

Figure 29: Members of the DMC

DMC meetings should be convened every three months (i.e. quarterly). The functions of the

Operational management of recreational activities such as ensuring the AtoN and

demarcation markers system is in place and setting times for use of the Dam (no

recreational activities can take place between sunset and sunrise, unless special

permission is granted);

Conveying the Management Objectives and decisions pertaining to the Dam to the

relevant stakeholders;

Management of the UPN System as part of the CIWSP;

Assessing commercial and recreational opportunities at the dam. As such, an agenda

item related to the Strategic Plan for Commercialisation is required;

Incorporating the management requirements linked to the system’s operating rules into

decision-making;

Organising and facilitating the bi-annual Dam Users’ Open Day. All stakeholders should

be invited to this meeting so that issues regarding use of the Dam can be discussed. If

necessary, significant issues can be escalated from the Open Day to the OMC and then

the RSC to facilitate resolution. The Open Day also provides an opportunity for the DMC

to inform the Dam’s users of all rules and regulations governing access and use. At least

three members of the DMC (including a representative from Umgeni Water) should

attend the Open Day to ensure that all comments raised are noted and raised at the

DMC meeting.

All responsibilities and operations must be compliant with relevant financial and procurement

legislation, regulations and guidelines.

If deemed necessary and it is approved by the DMC, management committees may be

established around specific issues, such as community empowerment and safety, and may

include contractors that are appointed for these activities.

4.2.3 Operational Management Committee

The OMC (refer to Figure 30) will function at a catchment level and will provide high level

guidance for all dams that are situated within one catchment. This is an existing reporting


November 2016 55

line between Area Managers for various schemes, the Regional Manager and the Director:

Operations.

The DWS Cluster: Integrated Environmental Engineering (IEE) that sits on the DMC will

provide feedback at the OMC on Nagle Dam. The implementation of the RMP will be added

as an agenda item, hence providing an opportunity to discuss the RMP. The Regional

Manager will be fully aware of all commercial and/or recreational activities/opportunities at all

dams within the cluster.

Figure 30: Members of the OMC

4.2.4 RMP Steering Committee

The RSC, which was established to deal specifically with RMPs, is made up of

representatives from National Government Departments and relevant Agencies and is

managed by DWS. The committee meets every six months.

The main functions of the RSC are as follows:

Ensure that both the DMC and OMC are performing all necessary functions;

Liaise with the individual members of the specific sectors that they represent;

Provide high level guidance on recreational use in terms of their respective mandates to

the OMC and DMC; and

Ensure that the necessary continuous support is provided by the different government

sectors to the DMC with the aim of achieving sustainable utilisation of the resource.

Relevant matters raised at the DMC meetings will be escalated to the OMC and the RSC to

receive the appropriate action from the mandated bodies.

Figure 31 lists the members that are typically represented on this committee.

4.2.5.2 Agreements

Formal agreements represent one of the main management tools available to

ensure proper use of the Dam in line with the RMP’s requirements.

All the existing agreements shall be reviewed within 12 months of the RMP being

approved. This is to ensure that the agreements are aligned with the management

requirements of the RMP.

1) Agreements for the Implementation of the RMP

Umgeni Water may delegate responsibility for the implementation of the gazetted

RMP to Msinsi, who is currently responsible for managing access and utilisation of

the property for recreational purposes. If this is the case, the agreement between

these parties should make provision for satisfying the requirements of the RMP,

which as a minimum must achieve the following:

Specific conditions imposed by Umgeni Water for any agreements with other

parties on the use of the property for recreational purposes;

Terms and conditions regarding equitable access;

Guidance on the use of the State Resource for Public-Private Partnerships

(PPP) in line with Treasury’s requirements;

Safety management to be in line with SAMSA requirements;

Targets and objectives for the management of the Dam;

Roles and responsibilities regarding the following:

Maintenance of AtoN and demarcation markers;

Maintenance of Wash Bays;

Maintenance of recreational infrastructure;

Maintenance of fencing;

Firebreak maintenance;

Managing sensitive environmental features (e.g. wetlands);

Control of alien invasive species;

Maintenance of the UPN System including signage;

Management of agreements with other recreational users (as relevant);

Responsibilities on monitoring development and access targets (as part of

agreements with other recreational users); and

Conditions for the negotiations of agreements with recreational clubs.


November 2016 58

2) Recreational Use Agreements –

Recreational use at Nagle Dam must be undertaken through an appropriate legal

framework, as relevant to the type of use. Umgeni Water/ Msinsi must enter into

agreements with all recreational clubs on the use of the Dam. Recreational Use

Agreements must be developed in line with the conditions stipulated in the

agreement between Umgeni Water and Msinsi (if relevant).

These agreements should also be presented to the DMC prior to signature to

ensure the vision and objectives of the RMP are satisfied. All agreements must be

finalised within 12 months of the RMP being gazetted.

3) Access Agreements –

Access Agreements provide a legal mechanism to ensure that all management

requirements are being met when granting access to the property.

Examples where Access Agreements may be required at Nagle Dam include:

Allowing the surrounding community access to gather firewood;

Allowing the surrounding community access to traverse the property to reach

either sides of the Dam; and

Certain portions of the property are not fenced due to maintenance

complications. This includes a section along the northern shoreline (refer to

Figure 32) as well as a section of the property to the south of the dam wall.

Agreements are required with the relevant Traditional Authorities, which makes

provision for access and livestock grazing in these areas.

Figure 32: Cattle along northern shoreline of Nagle Dam

The ITB and Traditional Authorities surrounding the property, as well as the clubs

that make use of the Dam, must be made aware that access should only be through


November 2016 59

authorised points. Accessing the property through unauthorised access points is an

illegal activity unless the parties concerned enter into a formal agreement with

Umgeni Water/ Msinsi.

These agreements should be updated within 12 months of the RMP being gazetted.

4) Safety of Navigation Agreement –

In addition to its common law responsibility, DWS is in terms of the requirements

described in the NWA (amongst others) responsible for the safety of watercourses

(including dams). Umgeni Water is responsible to provide the required fixed and/or

AtoN (e.g. buoys) for general navigation, according to prescribed specifications.

Nagle Dam, as well as other dams owned by Umgeni Water with high levels of

activity, can be included in the licence acquired by DWS for the UPN System.

Umgeni Water’s CEO will need to submit a formal request in this regard to DWS’s

Director General (Mzanywa pers. comm., 2016). DWS will then need to enter into

an agreement with Umgeni Water to ensure that SAMSA’s requirements are

satisfied.

These agreements should be updated within 1 year of the RMP being gazetted.

5) Event Applications –

All events must be managed through an event application process. The event

application must be made to Umgeni Water/ Msinsi and must be approved by the

DMC.

These applications must follow a specific template and will include the following:

Number of participants;

Emergency Response Plan;

Advertising and branding will need to be in line with Umgeni Water’s/ Msinsi

communication requirements;

Access points to be used; and

Specific requirements.

Furthermore, all events must meet the requirements of the Safety at Sports and

Recreational Events Act (Act No. 2 of 2010).

6) General Principles and Requirements

The following general principles and requirements need to be incorporated into the

various agreements, as relevant:


November 2016 60

Clear start and end dates and terms of renewal/extension;

Rights and obligations of both parties;

Formal access points to be used;

Umgeni Water’s exclusion of liability;

Terms and conditions of improvements made to the property, where relevant. All

improvements require consent from Umgeni Water and the DMC. Furthermore,

the financial consequences should this requirement not be met should also be

stipulated in the agreement. No permanent structures shall be built within the

1:100 year floodline without additional approval as required by Section 21(c)

and (i) of the NWA);

The extent of the rights to use the resource;

Clear instructions on the financial requirements of both parties, and where and

when money must be paid. All recreational clubs on state-owned land must be

managed in line with National Treasury requirements. Lease agreements for

use of state land should include fair remuneration at the current market value;

All agreements should include a cancellation clause if requirements cannot be

met;

All clubs or associations must be affiliated to a national sporting body

recognised by the South African Sports Confederation and Olympic Committee

(SASCOC). All agreements must include a cancellation clause if clubs or

associations fail to obtain affiliation within one year from date of signature of the

agreement;

Limitations to the number of people allowed to access the water surface based

on the carrying capacity of the Dam. In addition, the carrying capacity of the

CIWSP wash-bays must be adhered to;

A list of current and potential recreational activities allowed at the Dam;

Requirements for safety, disaster management and emergency response plans;

Duties and responsibilities of either party regarding maintenance, management

and infrastructure;

A list of prohibited activities;

Requirements for subletting portions of the leased area (if allowed);

A mandate for programmes to assist in equitable access and redressing past

imbalances at the Dam, such as sponsored gate-fees / access cards / sliding

scale of fees for members of previously disadvantaged communities. This

should be in line with the RMP. The DMC will then be required to report against

all targets at the OMC;

All agreements must include a cancellation clause should community access

targets not be met; and

All recreational activities must be in line with the RMP, which once gazetted,

becomes the mechanism to control and manage recreational use. Although no


November 2016 61

Section 21k Water Use License Application (WULA) is required, all activities

must comply with all other relevant legislation (refer to Section 2.3); and

Operating rules of the system to be considered, based on the recreational of

commercial use proposed.

4.2.5.3 National Affiliations and Development Targets

All recreational clubs (e.g. canoeing and fishing) should be affiliated to a SASCOC

affiliated organisation. The development targets set by the National Organisations

must be met.

4.2.5.4 Community Participation and Beneficiation

Community participation and beneficiation is one of the key objectives for the future

management of Nagle Dam, as established as part of the compilation of the

preceding RMP deliverables.

Provision is made in the Strategic Plan (see Section 4.5) to pursue this objective

further.

4.3 Zonal Plan

4.3.1 Defining a Zonal Plan

Generally, a Zonal Plan is a spatial representation of the designated areas on the water

surface and along the shoreline area where certain uses and restrictions apply, and which

depicts features that are relevant to the potential future recreational use of a dam.

The individual Zonal Plans for Nagle Dam were compiled based on the following:

Understanding the current recreational uses as well as identifying additional potential

recreational and commercial opportunities;

Establishing the Dam’s carrying capacity; and

Demarcating management zones in terms of the water surface, shoreline and general

property together with an indication of the preferred activities within each zone.

The following needs to be borne in mind for the Zonal Plans:

The demarcation of the various zones was based on the extent of the watercourses

(uMngeni River and Nagle Dam) reflected in the latest aerial photography received from

Umgeni Water. Going forward, these zones need to be updated as follows (as relevant) -

The Surface Water Zonal Plan needs to be based on the FSL of the Dam, once

confirmed; and


November 2016 62

The Shoreline Zonal Plan needs to be based on the 1:100 year floodline or

delineated riparian zone (both to be determined), whichever is greatest.

A conservative approach was adopted to demarcating the zones in terms of ensuring the

safety of visitors, safeguarding infrastructure and facilities at the Dam, as well as

protecting sensitive environmental features. Depending of the current status of the land,

the following default zones were allocated to the general property -

Conservation, if undeveloped and unaffected by historic land clearing; or

Facilities, if the land has been affected by operational activities and structures.

4.3.2 Current Recreational Uses

The current main user groups at Nagle Dam, and their associated activities, include the

following:

Canoe clubs (Lembethe Canoe Club) - canoeing;

Fishing clubs - recreational fishing;

Change a Life Academy - trail running and canoeing (amongst others);

Event organisers - fishing and canoeing competitions, running, mountain biking and

general gatherings (e.g. Day of the Clubs motorbiking event);

General members of the surrounding community – picnicking and fishing (recreational

and subsistence);

Business groups - conferencing and team building; and

Tourists - accommodation, game viewing, hiking, picnicking and fishing.

November 2016 63

4.3.3 Potential Recreational and Commercial Activities

A matrix was used to determine the feasibility of possible recreational and commercial

activities in line with the operational requirements of the Dam, the biophysical environmental

conditions and safety requirements. The ratings that were used to determine the viability of

these activities are shown in Table 6.

November 2016 66

Based on the appraisal in Tables 7 – 9, the main potential activities that are not already

practiced at Nagle Dam and that could be considered in the future include the following:

Dedicated trails set out for hiking and mountain biking;

Guided tours to Table Mountain, with approval from Traditional Authorities;

Junior angling school for local communities;

Boat tours on the dam;

Pedal boats;

Horse trails;

Wedding venue, possibly using the existing facilities (e.g. conference hall);

Conducting scientific research at the dam (e.g. aquatic health);

Traditional ceremonies / baptisms, involving the surrounding Traditional Authorities;

PPP for aquaculture by resuscitating the old fishery on the property;

Environmental Education Programme, focusing on the environmental features present at

the Dam, which could include other activities such as zip line, obstacle course and Zulu

Cultural Experience;

Farmers / Craft Market, possibly using the main picnic site; and

Activities associated with paddling, such as kayaking water polo, kayak fishing, and

stand up paddling.

Proposals for any future recreational or commercial activities can be put forward to the DMC

and these can be assessed on a case-by-case basis (consider criteria listed in Section 3.3)

to ensure that Nagle Dam’s vision and desired state are not compromised and to avoid

conflict with the Management Objectives (Section 3.2). Any proposed activities would need

to be aligned with the Zonal Plans shown in Figures 34 and 35, unless adequately

motivated, and ensure that the Dam’s carrying capacity (Section 4.3.5) is not exceeded. The

appropriate Management Tools (Section 4.2.5) would also need to be applied.

4.3.4 Measures to Facilitate Current and Future Recreational Activities

The following needs to be taken into consideration for the current and future recreational

activities:

Access Point

All formal access points need to be clearly demarcated (signage) and manned. All visitors

must be registered and be provided with a copy of the rules and regulations.

Suitable signage shall also be displayed at the access points (e.g. disclaimer, prohibited

activities, safety requirements, times for use of the Dam, etc.).


November 2016 67

Parking Facilities

Safe and secure parking facilities would need to be provided, depending on the types on

uses permitted and number of visitors expected. The design of the parking facilities would

need to take into account the requisite specifications, best practices, gradient, access, etc.

Ablution Facilities

Ablution facilities are available at the main picnic area. Additional ablution facilities may be

required for the recreational users, which must cater for males and females. These facilities

must be centrally located for ease of access.

As a general note, any sanitary facilities would need to be managed to prevent any

contamination of the environment and the water body.

Hiking/Walking and Biking Trails

Formal hiking/walking trail and biking trail could be established on the property. Provision

needs to be made for the following:

Best practices for trail design;

Measures to control erosion;

Crossings for natural drainage lines (e.g. elevated walkways) that occur along the

walking trails;

Signage;

Ablution facilities;

Benches; and

Litter bins.

The conduct of the trail users would need to be controlled in terms of littering, managing fire

risks and prohibiting unlawful access to traditional land. Motorised vehicles shall not be

permitted on the trail and shall be prevented through proper design and detailing.

Fixed features

The proposed fixed features include benches, picnic benches, litter bins, signage and

restrooms, which will be strategically dispersed on the property along the trails and public

use areas. The features need to be properly maintained.

The visual impacts associated with these features need to be minimised, through placement,

painting, etc. Strict control over fire risks to be exercised.


November 2016 68

Access to Vessels

A slipway is available at the Dam, but will be for the exclusive use of the dam operator. If

required, the slipway could be utilised for emergency purposes. No public use of the slipway

will be allowed.

Additional launching areas should be investigated if the associated recreational uses that

require such facilities are deemed to be feasible, which should make provision for vessels to

access the dam. Apart from recreational use, it is also accepted that access will be required

to allow for the maintenance of dam-related infrastructure.

The Zonal Plan includes areas defined as “no wake” zones where the motorboat that is to be

used by the dam operator must travel at the slowest possible speed required in order to

maintain steerage and headway. No access to any vessels will be permitted to buoyed

restricted areas, such as the safety zone at the dam wall.

Fishing

Recreational fishing is currently allowed at the Dam, at areas accessible to the public.

Jetties, not impacting on dam safety and operation, can also be built to support this activity.

Fishing will not be permitted in sensitive areas and prohibited access zones. Gillnetting is

also not allowed on the property.

Requirements for stocking the dam with fish and the management of recreational fishing

would also need to be taken into consideration.

Community Access

The following matters pertaining to current access to the Dam by the surrounding

communities need to be addressed:

Various parts of the property are not fenced off and are less actively managed.

These parts are used by the community to gain access to the watercourse, for cattle

grazing and to gather firewood.

Even where fences have been erected, foot gates have been installed to allow the

community to traverse the property to access the area to the south. The community

thus traverse the property in a relatively uncontrolled manner.

The feasibility of a pedestrian bridge is under consideration by Umgeni Water. The

movement of the community members on the property needs to be controlled.

A tunnel within the diversion weir allows the community to cross beneath the dam to

access the area to the north. Once the tunnel is exited in the south, the dam property

can be traversed in a relatively uncontrolled manner by following the primary access

road that leads over the dam wall. A dedicated route needs to be clearly defined to

allow for safe movement across the property.


November 2016 69

Uncontrolled access by livestock is observed on the entire property. A contributing

factor to the abundance of livestock on the property is the broken cattle grid along the

P26.

The shoreline along the northern part of the dam is not accessible for use, apart from

the tunnel underneath the diversion weir. A public road grants access to the

settlements to the area north of the dam. Cattle and members of the community are

observed along the northern shoreline, within the property.

4.3.5 Carrying Capacity

The Methodology for Carrying Capacity Assessment: Recreational Water Use was used to

determine the degree of recreational use that is possible and sustainable on the water

surface at Nagle Dam. Calculating carrying capacity for recreation is a vital step to ensure

that recreation at the Dam is safe and that users do not feel crowded and enjoy their use of

the water surface.

It is noted that low impact use in the form of paddling is currently undertaken at the Dam,

and is advocated as one of the future preferred activities on the water surface. Recreational

fishing boats with electric motors are also permitted at the Dam. Sailing and boating are

already enjoyed on other dams on the uMngeni River, which can be regarded are more

suitable venues for these uses. The size and unique shape of Nagle Dam also restrict these

more intensive types of uses.


November 2016 70

There are three kinds of carrying capacity:

1. Physical Carrying Capacity (PCC) - this is the maximum number of users that can

physically fit onto the water surface at any given time;

2. Real Carrying Capacity (RCC) - this is the maximum number of users that can use the

resource once corrective factors (such as wildlife or weather conditions) that are unique

to the Dam are taken into account; and

3. Effective Carrying Capacity (ECC) - this is the number of visitors that can use the

resource, given the management capacity available at the Dam.

Each level constitutes a corrected capacity level of the preceding level. The PCC is always

greater than the RCC, and the RCC is greater than the ECC, thus: PCC > RCC and RCC ≥

ECC.

The process of establishing the carrying capacity is normally determined through the

following tasks:

Analysis of recreation and water resource management policies;

Analysis of objectives of the water resource;

Analysis of current recreational water use;

Definition, strengthening or modification of policies regarding recreational water use

management;

Identification of factors influencing recreational water use; and

Determination of the recreational water use carrying capacity.

4.3.5.1 PCC

Formula: PCC = A ÷ U/A x Rf

A = area available for public use;

U/A = area required for each user in terms of ha/craft; and

Rf = Rotation Factor (the number of visits per day)

A is calculated as the area of the water surface at FSL, which is 156 hectares (ha).

Although it is not realistic to consider the entire area of the dam at FSL for various

factors (e.g. dam level fluctuations, no-go areas, etc.), it provided a point of

departure for estimating the carrying capacity. Nagle Dam is generally operated at

80% full and A thus needs to be adjusted to 145 ha.

There are a number of studies and technical articles available that discuss

approaches to determine the area required by various types of recreational uses on

dams. Common users normally considered in calculating the U/A, based on the

standardised approach adopted by DWS for RMPs, are listed in Table 10. In the


November 2016 71

case of Nagle Dam, based on the current use and limitations with regards to the

Dam’s size and shape, the U/A was conservatively assumed to be 1 ha per user.

Table 10 Requirements for water crafts

Craft Water Depth (m) U/A (ha/craft)

Canoes >0,6 0,5

Windsurfers >0,6 0,5

Rowing >1,0 0,5

Dinghies >1,0 1,0

Yachts >1,8 2,0

Powerboats >1,4 4,0

Fishing >1,0 4,0

It was assumed for Nagle Dam that the Rf was 1 visit per day.

Thus PCC = 145 ha ÷ 1 x 1 = 145 crafts.

4.3.5.2 RCC

Formula: RCC = PCC x (100 – Cf1)% x (100 – Cf2)% x … (100 – Cfn)%

Cf = a corrective factor expressed as a percentage.

The RCC takes into account factors that limit recreation. In this case limiting factors

include (refer to Zonal Plans in Section 4.3.6 - 4.3.8):

1. Dam wall buffers (calculated as 3.9 ha);

2. Safety no go zones (calculated as 6.5 ha); and

3. Areas demarcated for conservation purposes, where no recreational use is

permitted (not applicable in terms of Nagle Dam’s FSL).

The first two bullets above equate to 10.4 ha which is 6.7% of the Dam’s water

surface. Note that mooring zones and swimming areas are not relevant at the Dam

and were thus excluded from the RCC calculation.

Given the susceptibility of Nagle Dam to pollution due to its size and operating

rules, water quality restrictions also need to be considered. A risk factor of 50% was

applied to make provision for the aforementioned aspect.

Thus RCC = 145 x (100 – 6.7)% = 135 – 50% = 68 crafts on the Dam at any given

time.


November 2016 72

Note that there may be other corrective factors that need to be taken into

consideration, such as limitations to public access, maintenance periods, etc. These

factors could reduce the number of crafts that can utilise the Dam.

4.3.5.3 ECC

Formula: ECC = (Infrastructure Capacity x Management Capacity) x 100/ RCC

MC = Management capacity based on staff and budget.

Infrastructure Capacity is normally associated with slipways required to launch

boats. Direct access to the water is currently gained from the main picnic area and

infrastructure capacity is thus not regarded as a constraint. A value of 1 is thus

allocated to Infrastructure Capacity.

ECC is the maximum number of visitors that the Dam can sustain, given the

management capacity available. As mentioned, Msinsi manages the recreational

activities at Nagle Dam and existing facilities and control measures are in place on

the property in this regard (refer to organogram in Figure 7). However, 68 crafts is a

considerable number compared to the current level of recreational use of the water

surface. The overall management capacity at this stage was assumed to be 50%,

as additional resources may be required to deal with such a large number of

vessels. Therefore the ECC was calculated to be 34 crafts.


November 2016 73

4.3.6 Water Surface Zonal Plan

The Zonal Plan for the water surface at Nagle Dam, which is provided in Figure 34, was

compiled by taking into consideration the following factors:

Operational requirements of the Dam;

Safety requirements of each activity;

Types of activities (in terms of contact); and

Environmental requirements.

Information regarding the current and potential activities in each zone, as well as the related

management requirements, are provided in Table 11.

As a minimum, the following information needs to be added to the Water Surface Zonal Plan

(once it becomes available and as relevant):

Fluctuating water levels (as relevant);

Location of fixed and floating AtoN;

Location of demarcation markers;

Suitable location for UPN zones and boards; and

Fence line boundaries.

4.3.7 Shoreline Zonal Plan

The Shoreline Zonal Plan is provided in Figure 35. It reflects the remainder of the Nagle

Dam property, excluding the water surface. Information regarding the current and potential

activities in each zone, as well as the related management requirements, are provided in

Table 12. The RMP advocates that no development be permitted within 100 m of the Dam’s

FSL, unless if it is accepted by the DMC on a case-by-case basis and if the relevant

statutory approvals have been acquired. Note that mining (including fracking) is not

permitted on the property.

As explained in Section 2.2.8, the Reserve Management Plan (Msinsi, 2012) divided the

majority of the property into different management units. The Shoreline Zonal Plan

incorporates the wilderness area as a dedicated zone, but deviates from the remaining

management units (defined as low and high intensity in the Reserve Management Plan)

based on management objectives and the characteristics of the balance of the area.

As a minimum, the following information needs to be added to the Shoreline Zonal Plan

(once it becomes available and as relevant):

Fluctuating water levels;

Suitable location for wash bay(s);

Location of fixed and floating AtoN;

Location of demarcation markers;

Suitable location for UPN zones and boards;

1:100 year floodlines; and

Delineated riparian habitat.

November 2016 90

4.4 Financial Plan

As mentioned, a Financial Plan generally provides information on how revenue generated

through recreational use should be used. Charges for use of the property for recreational

purposes are ideally applied towards funding water resources management, socio-economic

development and empowerment of local communities. Msinsi is charged with managing

public access and recreational activities at Nagle Dam.

Currently, the following recreational activities at Nagle Dam generate an income:

Accommodation (Nagle Lodge, Msinsi Lodge, Hatchery Lodge, tented camps);

Special events;

Conferencing;

General access for picnicking;

Game viewing;

Fishing; and

Hunting.

Figure 37: Examples of recreational facilities at Nagle Dam

There are also opportunities for PPPs which could further unlock the economic potential of

the Dam. With PPPs, the private party assumes the financial, technical and operational risks

but receives a benefit in return. A PPP could allow Umgeni Water to make a state asset such

as Nagle Dam available to private parties who wish to engage in tourism related commercial

operations. The development of PPPs in remote areas often require related infrastructure

upgrades and thus there is the opportunity for new infrastructure investment and


November 2016 91

development and related services which would benefit local communities. It is noted that the

P26 was being upgraded at the time of writing this report.

Although high cap PPPs result mostly in revenue generation, small cap opportunities (less

than R10 million - 2007 figures) are more likely to fulfil socio-economic objectives such as

job creation, promotion of Broad-Based Black Economic Empowerment (BBBEE), Local

Economic Development (LED) and Small, Medium and Micro-sized Enterprises (SMMEs). A

balance between high and small cap opportunities may be required to ensure that revenue

generation occurs together with the promotion of equitable access and job creation at the

Dam. The Strategic Plan (Section 4.5) proposes opportunities for PPPs for unlocking the

Dam’s socio-economic potential.

While the tariff structure can be used for revenue generation, it should not be used to deny

people access to the dam. Thus it should take into account the socio-economic status of

recreational users. For example, a sliding scale, cross subsidy fee structure and/or

contractual obligations which ensure equitable access must be considered when setting a

fee.

The Business Plans will provide financial frameworks to undertake certain prioritised

interventions.


November 2016 92

4.5 Strategic Plan

The Strategic Plan is informed by the objectives determined during the Visioning exercise and through research on feasible

opportunities for Nagle Dam.

The aims of the Strategic Plan are as follows:

Address the issues identified as part of stakeholder participation, survey of encumbrances and RMP research. This includes

interventions over and above what is currently in place through existing management structures; and

Provide guidance on exploring the opportunities identified at Nagle Dam.

5 WAY FORWARD

5.1 Business Plans

Based on the management objectives identified for Nagle Dam (refer to Strategic Plan

contained in Section 4.5), various Business Plans will be developed which will be captured

in the final RMP deliverable. The Business Plans will summarise the operational and

financial objectives of the RMP and will contain the interventions, resources and timeframes

required to achieve these objectives.

5.2 Review Cycle

The RMP presents a twenty-year vision for Nagle Dam, which is to be achieved through the

integrated planning, management and zoning presented in Section 4 of this document and

the subsequent Business Plans.

This RMP will be reviewed every 5 years and revised as necessary, according to changing

priorities, constraints and achievements. The Business Plans will be updated annually. The

review periods for the RMP and Business Plans are shown in Figure 38.

6 CONCLUSIONS

It is believed that through the RMP development process that was undertaken, adequate

opportunities were granted to determine the perspectives, needs and concerns of the

authorities, stakeholders and community members with regards to Nagle Dam. The ensuing

RMP components, which include the vision, Management Objectives, Institutional Plan,

Zonal Plans and Strategic Plan have duly incorporated the outcomes of the process. In

particular, the findings of the Encumbrance Survey and Research Report shaped and guided

the identification of the key management priorities for the Dam.

Ultimately, the RMP serves as a tool for the sustainable and balanced management and use

of Nagle Dam. The successful implementation of this plan depends on the institutional

arrangements that are established together with the mechanisms that are to be employed,

as detailed in the RMP, to ensure that the dam’s management objectives are achieved.
