MERCER LAKE ASSOCIATION: LMI-Mercer Lake Water Quality,Hydrology, and Watershed Study

The Mercer Lake Association in cooperation with the Town of Mercer and the US Geological Service (USGS) will conduct a lake/watershed evaluation and develop a final lake/watershed management plan.

2. Work with Mercer lake Association to analyze & interpret USGS report.

3. Determine amount of suspended solids & phosphorus entering the lake from the downtown commercial area in the Town of Mercer.

4. Analyze alternatives to treat stormwater runoff from urban area.

5. Develop sub watershed action management plan for watershed planning area.
