The Michigan Clean Water Corps (MiCorps) was created in 2004 through Michigan Executive Order #2003-15 to assist the Michigan Department of Environment, Great Lakes, and Energy (EGLE) in collecting and sharing water quality data for use in water resources management and protection programs.
This report is a summary of the data that have been collected through the Cooperative Lakes Monitoring Program. The first page is a summary of the Trophic Status Indicators of your lake (Secchi Disk Transparency, Chlorophyll-a, Spring Total Phosphorus, and Summer Total Phosphorus). Where data are available, they have been summarized for the most recent field season, five years prior to the most recent field season, and since the first year your lake has been enrolled in the program.

Long Lake 2025 Aquatic Vegetation, Water Quality, and 2025 Management Recommendations
2024 saw an increase in Starry Stonewort, a particularly fast growing macroalgae that is difficult to manage. Curly-leaf Pondweed has increased in several areas, and Eurasian Milfoil appears to be under control. A few areas of nuisance natives and algae control were also addressed.
Water quality analysis reveals moderate nutrient levels, high water clarity, and concerns about phosphorus release from sediments due to low dissolved oxygen levels.
Algal blooms (floating balls of algae), are a nuisance. Unfortunately they can't be treated. They can be caused by high nutrient levels from rainfall runoff, warmer temperatures and water that isn't circulating.
If you do fertilize your lawn, consider creating a natural buffer between the shoreline and your lawn/yard. Anything you can do to minimize fertilizer runoff into the lake helps all of us.
Recommendations for 2025 include targeted herbicide treatments, selective removal of nuisance vegetation, and strategies to manage algal blooms. The report underscores the importance of ongoing monitoring and management to maintain the ecological health of Long Lake.
We remain committed to responsible lake management and appreciate the work RLS has continued to provide.
