Round 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 41 (Mesotrophic) and was determined using Secchi data. For a Shallow Seepage lake, this is considered Excellent. Shallow Seepage lakes do not stratify, or form separate layers of water, during the summer months and have no inlet or outlet.
Round Lake was monitored by volunteers between 2001 and 2020. 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. Reports and graphs featuring data collected by volunteers, DNR staff and others can be viewed below.
