Water Quality

One measure of a lakes health is the trophic state, which relates to the amount of algae in the water. The average summer trophic state for the last 5 years was 42 (Mesotrophic) and was determined using satellite water clarity observations data. For a Two-Story lake, this is considered Excellent.

Reports and graphs featuring data collected by volunteers, DNR staff and others can be viewed below.
