Lake Wee-Ma-Tuk Water Quality: Moving Forward
![Page 2: Lake Wee-Ma-Tuk Water Quality: Moving Forward. Goals: Fishing Sport fish are sight feeders Recreation/Swimming Aesthetics Home Values.](https://reader037.fdocuments.in/reader037/viewer/2022110303/5517bb775503461b658b45c9/html5/thumbnails/2.jpg)
• Goals:
• Fishing• Sport fish are sight
feeders
• Recreation/Swimming
• Aesthetics
• Home Values
![Page 3: Lake Wee-Ma-Tuk Water Quality: Moving Forward. Goals: Fishing Sport fish are sight feeders Recreation/Swimming Aesthetics Home Values.](https://reader037.fdocuments.in/reader037/viewer/2022110303/5517bb775503461b658b45c9/html5/thumbnails/3.jpg)
• Getting Started:
• Previous water quality data• County Health
Department
• Additional water quality information?
• Previous lake use and inputs?
![Page 4: Lake Wee-Ma-Tuk Water Quality: Moving Forward. Goals: Fishing Sport fish are sight feeders Recreation/Swimming Aesthetics Home Values.](https://reader037.fdocuments.in/reader037/viewer/2022110303/5517bb775503461b658b45c9/html5/thumbnails/4.jpg)
For a given target area, we have:
Inputs: Addition of energy, water, sediment, chemical substances, and organisms from the watershed
• Cattle manure, septic, lawn herbicides and pesticides, sediments, agriculture, other chemicals
• Many factors determine the movement of nutrients and sediments within most landscapes
• Vegetative cover throughout watershed (trees/plants at lake edge)• Soil type• Slope length/angle• Frequency/intensity of rainfall
Outputs: Export of material to downstream, to the sediment or to the atmosphere
Internal Physical: Erosion, settling, lateral transport, thermal gradient, light penetration
Internal Chemical: Oxygen and pH fluctuation, transformation of compounds
Internal Biological: Contaminant uptake, growth, death, ecological interactions

Phosphorus:
The most important nutrient in lakes
Also the middle number on a fertilizer bag (should be 0)
Note Scotts fertilizer has just announced that it will remove phosphorus from residential market fertilizers..lawns don’t need it and lake certainly don’t need it.
![Page 6: Lake Wee-Ma-Tuk Water Quality: Moving Forward. Goals: Fishing Sport fish are sight feeders Recreation/Swimming Aesthetics Home Values.](https://reader037.fdocuments.in/reader037/viewer/2022110303/5517bb775503461b658b45c9/html5/thumbnails/6.jpg)
Too much phosphorus grows algae which leads to:
-potentially toxic blooms
- rapid sedimentation
- taste and odor problems
- depletion of dissolved oxygen
- fish kills
- decline in property values
Easier to keep it out initially, than take it out later!
History of Lake Wee-Ma-Tuk may mean:
• Existing sediment from loadings in the past that may release nutrients over time

2010 Phosphorus Experiment

Solutions:
Soil stabilization and buffer strips
• Use of native prairie and wetland plants
• Rid yourselves of the non-natives and invasives that don’t help the situation
• Difference in root structures for soil stabilization and nutrient uptake
• Aesthetics!
• Home Values—we’re talking money here! (Maine found a 20% drop in property values if lakes bloomed)
• Recreational use and health
• Fishing
• Swimming
• Wildlife
• Goose deterrent

Solutions:
If you have major algae blooms and loading, you may need:
Watershed actions (first)
First- watershed reductions in loads related to development, land-use, fertilization, impervious surfaces. “Infiltrate rather than runoff”
In-lake actions, if needed (once watershed is under control)
(include dredging, aeration, circulation, biomanipulation)
• P inactivation through use of chemicals
• “Anti-fertilizer” treatment – coagulates and binds phosphorus and many other contaminants – changes internal processes
• Most often applies aluminum compounds to lakes with strong internal recycling

Lessons Learned:
• Have clearly stated goals (once you know the issues)
• Involve all essential parties (and maybe the non-essential ones too) as early as possible in the planning stage
• Homeowners• Government (local and state, as needed)
• NRCS• Illinois Volunteer Lake Monitoring Program
• Recognize the boundaries of the target area, but also consider the influences from outside that area
• Focus on what you can control first, then talk to others outside
• Think in terms of altering processes to reach desired ends, not just altering some feature at some instant in time
• Evaluate expected results in terms of conditions over a decade to a century – and consider adaptive management
• Assess costs based on long term enhancement or maintenance

Illinois Volunteer Lake Management Program (IVLMP)
•Educational program and cost-effective method of gathering information on lake health and management

• Increase citizen knowledge and awareness of the factors that affect lake quality so they can understand the lake/watershed/ecosystem and make informed decisions.
• Encourage development and implementation of sound lake protection and management plans.
• Provide historic data to help document water quality impacts and support lake management decision-making.
• Provide a guide for the implementation of lake protection/restoration and a framework for technical assistance for cooperative lake and watershed management projects.
