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 57 (Eutrophic) and was determined using satellite water clarity observations data. For a Shallow Headwater lake, this is considered Good. Shallow lakes are those that do not stratify during the summer months, so the water near the surface may be impacted by resuspension of sediments. If a lake's watershed is less than 4 square miles, the lake is classified as a Headwater Lake.
