Washington County, 45 Acres
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 56 (Eutrophic) and was determined using satellite water clarity observations data. For a Deep Headwater lake, this is considered Fair. Deep Headwater lakes stratify, or form separate layers of water, during the summer months and have a watershed area less than 4 square miles.
