Upper Silver Creek: Open House Boards

Upper Silver Creek Watershed Plan

Open House PhotosAugust 19th & 20th (Troy & Hamel)


Welcome!Thank you for coming this evening to the Open House for the Upper Silver Creek Watershed Plan.

Tonight you will have the opportunity to learn more about the Upper Silver Creek Watershed Plan and provide input that will be used to help develop the plan.

Elements of the Watershed Plan: Document Existing Conditions in the Watershed:Soil Types, Land Cover, Topography

Pollutant Loading (Sediment, Phosporous, Nitrogen)

Stream Conditions

Areas of Frequent Flooding

Community Flood Survey Develop of Watershed Goals and Objectives

Watershed Based Plan:Recommendations of best practices and strategies.

Prioritize future actions and projects.

Sources of potential funding to assist in implementation.

Goals and Objectives: Document existing conditions.

Decrease flood damage. Improve water quality. Collaborate with multiple partners (landowners, communities, agencies, etc) for solutions and strategies.

Identify sources of funding. Educate about watershed conditions.

Establish partnerships for implementation and future actions.

We Want Your Input!

Please take our survey!Please take a moment tonight to fill out the community flooding survey for homes, businesses, and property owners in the Upper Silver Creek watershed. This will help in determining strategies and recommendations for addressing flooding problems in the watershed.

An online version of the survey is available at: www.surveymonkey.com/s/UpperSilverCreek

The survey will be open until September 12th.

Thank you for your

input and comments!

Watersheds in Madison County

Overview of Stormwater PlanThe Madison County Stormwater Plan is the overall framework for stormwater management in

the county which guides regulations, identifies flood and water quality problems, establishes best

management practices, and prioritizes work to be done.

The Upper Silver Creek watershed is one of ten watersheds that will be part of the overall

Stormwater Plan. Direction and approval for the Stormwater Plan comes from the Madison

County Stormwater Commission, whose members include County Board members and municipal

representatives.

Impaired Streams (303d listed streams, 2014)

Project Area

0 1.5 30.75Miles

What is an

impaired stream? Streams in Illinois are regularly

analyzed by the Illinois EPA for a variety

of conditions including biological,

physicochemical, physical habitat, and

toxicity data. Streams are analyzed

using categories including: aquatic life,

fish consumption, public water supply,

aesthetic quality, and primary contact.

Each assessed stream segment is then

rated as Fully Supporting (good), Not

Supporting (fair), or Not Supporting

(poor) for each applicable category. If a

stream is rated at fair or poor, then the

stream is categorized as “impaired” .

How many impaired

streams are there in

Illinois?Approximately 34,762 miles of streams

in Illinois are assessed on a regular basis.

This is out of a total of approximately

119,244 stream miles in Illinois. Out of

the 34,472 miles of assessed streams,

approximately 15,398 miles (44%) have

been designated as “impaired”.(1)

What is causing the

impairment?For Silver Creek, the impairment is

caused by dissolved oxygen, manganese,

phosphorus, and sedimentation. For

Troy Creek, the impairment is caused by

phosphorus.(1)

Methodology - Estimating

Pollutant LoadsOverview: Nutrient and sediment loads for the Upper Silver Creek watershed

were calculated using the Spreadsheet Tool for Estimating Pollutant Load

(STEPL). STEPL employs simple algorithms developed though scientific research

to calculate nutrient and sediment loads from different land uses.

STEPL computes watershed surface runoff, nitrogen and phosphorus loads, and

sediment delivery based on various land uses and management practices.

Data sources: The most recent National Land Cover Database (2011) was used as

the source for land use data. Animal (livestock) data was obtained from the 2012

county level agricultural census database. Runoff volumes were based on long-

term precipitation records from the Southern Illinois University weather station

at Belleville. The remaining user input parameters were obtained from the STEPL

On-line Data Access System ( http://it.tetratech-ffx.com/steplweb/steplweb.html)

Sediment calculations: The annual sediment load (sheet and rill erosion only) is

calculated based on the Universal Soil Loss Equation (USLE) and the sediment

delivery ratio. Gully and streambank erosion are based on streambank stability

assessments that are currently ongoing and will be added to the calculations

upon completion.

Note: The estimated pollutant loads are based on a model, and do not

necessarily reflect individual parcel/site conditions. The model will be used to

help evaluate best management practices (BMPs).

Note: Sediment load estimates does not include gully and streambank estimates at this time. Gully and streambank estimates are still being calculated and will be includ-ed in the Existing Conditions Report this fall.


Water Quality Overview

Sources of Non-Point

PollutionThere are two types of water pollution:

“point source” pollution and “non-point

source” pollution. Point source pollution is

discharged through a pipe or some other

discrete source.

Non-point source pollution is the result of

many sources, when combined, can create

impaired streams, lakes, and water bodies.

Examples of non-point source pollution are

metals, chlorides, oils, trash, fertilizers (nu-

trients), pesticides, and pet waste (E. coli).

The graphics above and left illustrate com-

mon sources of non-point source pollution.Sources: Top graphic - Environmental Protection Agency; middle - University of Tennessee, Knoxville, Department of Landscape Architecture; left - NC Department of Environment & Natural Resources

Water Quality BenefitsEnsuring clean water in the Upper Silver Creek

Watershed has numerous benefits including:

clean, safe supplies of drinking water; stream,

ponds, and lakes suitable for recreation;

navigable shipping channels further downstream;

and healthy habitats that supports a wide variety

of plant and animal life.

FloodingOverview

A Long-Term Approach

Addressing Flooding

Issues

Solving all flooding problems will not happen

overnight. Long term strategies will be needed

to reduce flooding impacts in the watershed.

This plan will be an important step in the

process, especially with a mailed and online

survey in the fall of 2014 that will help

identify areas of flooding that occur outside of

designated floodplains.

Additional study and analysis will likely be

a key outcome of this process. This plan will

be a key component of the Madison County

Stormwater Plan.

Help Us Identify Existing

Areas of FloodingTonight there are detailed maps that the

planning team is using to assist in identifying

locations of existing flooding. Spend a few

minutes discussing existing areas of flooding

such as:

Locations of roads that are frequently over

topped by flood events.

Locations of homes, businesses, or structures

that are impacted by flooding.

Areas of erosion or other damage caused by

flooding or stormwater.

Watershed PlanningWatershed plans are a great way for multiple partners (local leaders, stakeholders, agencies, landowners, etc) to develop goals and objectives for the watershed. A plan will then help prioritize future actions and projects, and identify sources of funding and partners that can assist in implementation.Recent articles in FarmWeek have highlighted the benefits of watershed plans and opportunities for sources of funding such as the Conservation Reserve Enhancement Program (CREP) and EPA 319 grants.
