Maple Lake

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 Secchi data. For a Shallow Headwater lake, this is considered Excellent. 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.

Maple Lake has been monitored by volunteers since 1991. Volunteers monitor water clarity with a black and white Secchi disk. Volunteers are the source of the majority of Wisconsin's lake water quality data, and their dedication is greatly appreciated. Additional monitoring has been done through projects funded in part by DNR Lake Grants and Aquatic Invasive Species Grants. Reports and graphs featuring data collected by volunteers, DNR staff and others can be viewed below.
