Browns 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 46 (Mesotrophic) and was determined using chlorophyll data. For a Deep Headwater lake, this is considered Excellent. Deep Headwater lakes stratify, or form separate layers of water, during the summer months and have a watershed area less than 4 square miles.

Browns Lake was monitored by volunteers in 1996. Volunteers monitor water clarity with a black and white Secchi disk. Some also collect water samples, which are sent to the State Lab of Hygiene to be analyzed. Volunteers are the source of the majority of Wisconsin's lake water quality data, and their dedication is greatly appreciated. Browns Lake is also part of DNR's long term trend monitoring project. 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.
