Washburn County, 267 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 46 (Mesotrophic) and was determined using satellite water clarity observations data. For a Shallow Seepage lake, this is considered Good. Shallow Seepage lakes do not stratify, or form separate layers of water, during the summer months and have no inlet or outlet.
Matthews Lake has been monitored by volunteers since 1997. 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 Aquatic Invasive Species Grants. Reports and graphs featuring data collected by volunteers, DNR staff and others can be viewed below.
