Aquatic Ecosystem Research conducted a detailed water quality study of our lake between May and October of 2019. The bottom line is that our lake’s water quality is quite good and is actually improving.
Previous studies show a marked decline in water clarity and an increase in total phosphorus and alkalinity between 1934 and 1990. Most of that occurred between the 1970s and 1990s. Since then and particularly since we started biennial testing in 2015 phosphorus and nitrogen levels are generally trending down, water clarity is improving (as much as 20 feet last summer) and algae and cyanobacteria levels are low. One area that requires more attention is an increase in specific conductance. That indicates we may be getting too much storm water runoff containing salts and other deicing materials.
