About Lake Savers

To deliver ACTIONABLEstrategies torestore lakes to a balanced, pristinecondition for the benefit of currentstakeholders and future generations.

Lake Savers 4

Overview and Objectives

Urban Lakes receive more nutrients and pollutants from the

surrounding environment than they were designed to handlenaturally.

Even healthy lakes can experience spikes in pathogenicbacteria and nutrients due to rain events.

The key to keeping urban lakes healthy is to INCREASEtheircapacity to process nutrients and pollutants.

The Clean-Flo Restoration Process is the most effectiveapproach to keeping lakes healthy and safe for recreationaluse. This approach will:

Kill pathogenic bacteria that enter the lake by exposing

them to oxygen and sunlight continuously. Keep algae and weeds under control without the need

for chemical herbicides.

Improve the lake environment for fish, turtles, frogs, etc.

Five Key Points Guiding our Approach

to Natural Lake Restoration

1. Most water bodies are overfed and out ofbalance.

2. Conventional strategies are primarily peoplemanagement strategies not lake management

strategies.

3. Nutrient reduction (Internal & External)is theonly sustainable approach to Lake Restoration.

4. Lakes Need to Breath to Be Healthy!

5. Lake Savers can put your lake on a diet andexercise program utilizing ENGINEEREDAERATION and BACTERIAL AUGMENTATIONto restore health, balance and recreationalquality.

LAKE PROBLEMS

ROOT CAUSES

1. Most dollars arespent on Chemicals,Harvesting and/ orDredging which onlytreat symptoms.

3. Lake continues todeteriorate over time,treatment costs rise.

Lake Savers Lakes Need To Breathe To Be Healthy!!! 12

The Importance of Dissolved Oxygen

Oxygen Depleted Lake Oxygen Rich Lake

1. When oxygen runs out at the lakebottom phosphorus can release fromthe sediments and feed weed growthand algae blooms.

2. Anaerobic bacteria take overproducing ammonia, methane andhydrogen sulfide.

3. Organic muck accumulationaccelerates.

4. Fish Cant feed at the bottom (wheremost of the food is) stunting, fishkills possible, rough fish begin tooutcompete desirable species.

1. In the presence of oxygenPhosphorus stays locked in thesediments unavailable to weeds andalgae.

2. Aerobic bacteria thrive forming ahealthy bottom environment andbase for the aquatic food chain.

3. Aerobic bacteria literally eatmuck/organics converting it tocarbon dioxide and water.

4. Fish can feed all the way to thebottom creating a healthy fisheryboth in size and population ofdesirable species.

Engineered Aeration & BeneficialBacteria/Enzyme Treatments

How Engineered Aeration & BeneficialBacteria/Enzyme Treatments Work

A system of underwater air diffusers connected to shore-based compressor units by self-sinking airline.

Each system is custom engineered based on the specificneeds and requirements of each lake.

Water picks-up oxygen at the surface and is circulated back tothe bottom maintaining a continuous supply of oxygen

throughout the entire water column.

High oxygen levels and off-gassing reduce nutrient levels,reducing weed and algae growth.

Beneficial bacteria and enzyme products are added to restorebalance to the aquatic eco-system.

Beneficial bacteria that require oxygen, literally eat the organic

muck on the bottom.

milfoil and pondweed (2006).

Clean-Flo Engineered Aerationinstalled in June of 2006.

Clean-Flo bacteria and enzyme

treatment applied in July of 2006.

Results Beach opened in August of 2006,

remained open all of 2007, 2008, 2009and 2010

No significant re-growth of milfoil or

pondweed.

Dissolved oxygen maintainedthroughout water column all winter

despite shutting down the system for3 months.

Noticeable reduction in dead plant

material and muck in 2007.

Lakes Bridgeport & BenbrookFort Worth, Texas Area

About the Lakes

Two large water supply and recreational reservoirs.

High levels of manganese and hydrogen sulfide resulting in taste and

odor issues as well as increased treatment costs.

Represent two of the largest lake aeration projects in the country. 800

to 1000 acre treatment areas on 13,000 acre Lake Bridgeport and4,400 acre Lake Benbrook

Management Program

Clean-Flo System installed in 2010

Results

Data shows the ability to oxygenate

to a depth of 16 meters in 1 month ofcontinuous operation. Natural

turnover interrupted the process in2010. We anticipate sustaining a

minimum of 4 mg/l DO continuously.

About the Lake 25 Acre lake, max depth 12 feet

Completely over-run with milfoil and coontail.

Significant Blue-Green Algae through-out entire lake and

Filamentous Algae near the shoreline.

12 to 18 of organic muck accumulation on the lake bottom.

Management Program

Clean-Flo System installed in

July of 2010.

Bacteria and Enzyme treatmentapplied in July of 2010.

Results

Milfoil and coontail uprooted from

the bottom and starting to fail in 30days.

Most weeds decomposed and gone

within 60 days. Sand/gravel exposed at shoreline in

60 days.

Filamentous Algae eliminated and

Blue-Green Algae reduced in 60days.

CLEAN-FLO System AnticipatingQuestions and Concerns

Will the system create a safety hazard for boats? No, there is nothing at the surface of the lake. The diffusers and

airline are located on the lake bottom.

Will the system create a safety hazard for swimmers? No, the diffuser boils are very gentle and do not pose a hazard for

swimmers.

Will the system harm the lake in any way? No, the system is simply putting air into the water. The bacteria and

enzyme products used do not even require DEQ Permit Approval unlike herbicides.

Will the system deplete the lake entirely of plants and algae? No, the system will gradually bring the lake back into a healthy

balance of aquatic vegetation.

Will the system harm fish and other wildlife? No, fish benefit as will the entire food chain in the lake.
