Five Key Points Guiding our Approach to Natural Lake Restoration 1. Most water bodies are overfed and out of balance. 2. Conventional strategies are primarily people management strategies not lake management strategies. 3. Nutrient reduction (Internal & External) is the only sustainable approach to Lake Restoration. 4. Lakes Need to Breath to Be Healthy! 5. Lake Savers can put your lake on a diet and exercise program utilizing ENGINEERED AERATION™ and BACTERIAL AUGMENTATION to restore health, balance and recreational quality. © Lake Savers

Summary on What’s Wrong with Traditional Approaches the Lake Management LAKE PROBLEMS Algae Blooms Excessive Weed Growth Odor

1. Most dollars are spent on Chemicals, Harvesting and/ or Dredging which only treat symptoms.

Accumulation of Muck/Loss of Depth

ROOT CAUSES Internal Nutrient Loading

External Nutrient Loading

Oxygen Depletion

2. Few, if any resources are directed at solving root causes.

3. Lake continues to deteriorate over time, treatment costs rise.

The Importance of Dissolved Oxygen Oxygen Depleted Lake

Oxygen Rich Lake

1. When oxygen runs out at the lake bottom phosphorus can release from the sediments and feed weed growth and algae blooms.

1. In the presence of oxygen Phosphorus stays locked in the sediments unavailable to weeds and algae.

2. Anaerobic bacteria take over producing ammonia, methane and hydrogen sulfide.

2. Aerobic bacteria thrive forming a healthy bottom environment and base for the aquatic food chain.

3. Organic muck accumulation accelerates.

3. Aerobic bacteria literally eat muck/organics converting it to carbon dioxide and water.

4. Fish Can’t feed at the bottom (where most of the food is) – stunting, fish kills possible, rough fish begin to outcompete desirable species.

4. Fish can feed all the way to the bottom creating a healthy fishery both in size and population of desirable species.

Floating Islands – Trapping Nutrients at the points of Entry

© Lake Savers

10

Floating Islands for Reducing External Nutrient Loading What are Floating Islands? Porous mats made of a matrix of 100% recycled polyester and bonded together with a high grade marine foam for buoyancy. Highly flexible system with a multitude of design options for aesthetic and functional impact.

How do Floating Islands Work? They create a self-contained environment for vegetation that can absorb significant amounts of nutrients from the water. They mimic natural wetlands at a much lower cost than reclaiming upland areas and converting them to wetlands. They are most effective for Lake Restoration when used around storm drains and inlets to trap nutrients flowing into the lake.

Engineered Aeration & Biological Augmentation – Complete Water Body Oxygenation and Reduction of Internal Nutrient Loading

© Lake Savers

12

Engineered Aeration & Beneficial Bacteria/Enzyme Treatments How Engineered Aeration & Beneficial Bacteria/Enzyme Treatments Work A system of underwater air diffusers connected to shorebased compressor units by self-sinking airline. Each system is custom engineered based on the specific needs and requirements of each lake. Water picks-up oxygen at the surface and is circulated back to the 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 restore balance to the aquatic eco-system. Beneficial bacteria that require oxygen, literally eat the organic muck on the bottom.

CLEAN-FLO System Anticipating Questions 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? •

© Lake Savers

No, fish benefit as will the entire food chain in the lake.

Advantages of Leasing vs. Purchase of a Clean-Flo System Lake Savers is responsible for ALL maintenance and repair. The leasing agreement includes strict performance criteria for maintaining the equipment in peak operating condition. The customer is not making a capital investment in equipment that sits outdoors and at the bottom of a lake 365 days a year. Under the leasing agreement the equipment is guaranteed to be working in “as new” condition for the life of the lease. Results and performance monitoring is included in the lease. The leasing agreement offers an “out clause” after 30 months if the system is not delivering results as specified at lease inception. NOTE: Lake Savers will quote a purchase option with a minimum 4 year service contract if requested. Lake Savers will NOT sell a Clean-Flo System without a service contract.

Additional Costs Other Costs: Installation of Electrical service to compressor locations – customer responsibility.

Ongoing Costs: Electricity Costs – We can provide estimates as designs are developed.
