Sawyer County, 3294 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 38 (Oligotrophic) and was determined using satellite water clarity observations data. For a Two-Story lake, this is considered Excellent.
Round Lake was monitored by volunteers between 1995 and 1998. 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.
