Science Based Approach

• Enhanced Lab capabilities staffed with Research Biologists.

• State Certified Applicators.

• Designated Management Staff for Quality Control

• Clean/Well Maintained Equipment

Most Communities Possess a Storm Water System.

Impervious Surfaces

Impervious Surfaces

In Urban Environments…• Most of the water is directed into the community’s stormwater system.

• Along the way the stormwater picks up pollutants and/or nutrients.

• The excess run-off ends up in a stormwater basin and if not properly mitigated end up in our water systems.

Why is Maintaining Storm Water Systems Important?

Flood Control Pollution Abatement

Fish & Wildlife Habitat Aesthetics (Property Values)

Aging CommunitiesDo ponds have a life span?

How do we fix this?

How do we prevent this from happening in a newer community?

Invasive vegetation & Excess Algae

Identifying Symptoms

Symptoms • Reoccurring Algae and

Floating Weeds

• Persistent Odor

• Muck Accumulation

• Fish Kills

• Midge Flies

Steps to Lake Restoration

• 1. Identify problems using Lake assessments

• 2. Create a strategy to fix issue

• 3. Implement strategy

• 4. Allow time for the system to balance

Lake Assessments

• Diagnose the root cause of the problem ( Nutrient loading, muck accumulation, stratification, fish kill)

• Provide sound, science based recommendations for restoration

(Aeration, nutrient abatement, aquatic plantings, physical removal)

• Native Aquatic Planting

• Physical/Mechanical Removal

Aeration

A.K.A. Diffusers

• Moves water column

• Adds oxygen to the system

• Helps reduce odors

• Decreases stratification

Conclusion • Significant improvement throughout the 8-month period following the

installation of Vertex aeration systems.

• This increase in lake quality had proportionally increased favorable fish habitat

• Removal of stratification, increase in oxygen levels and reduction in nutrient levels

Native Aquatic Plantings

Benefits of Native Aquatic Plants

• Natural filter of pollutants

• Shading

• Provides habitat for fish & wildlife

• Erosion deterrent

• Enhances aesthetics of community

Most Commonly Planted

• Arrowhead (Duck Potato)(Sagittaria Lancifolia)Height: 3ft. Water: 6-12”

• Pickerelweed(Pontedera cordata)Height: 3ft. Water: 6-18”

• Gulf Spikerush(Eleocharia cellulose & interstincta)Height: 2.5ft. Water: 6-12”

• Softstem Bulrush (Scirpus validus)Height: 4-5ft. Water: 6-24”

• Golden Canna(Canna flaccida)Height: 3ft.Water: 12-18”
