Upper Nashotah Lake
Waukesha County, 131 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 40 (Oligotrophic) and was determined using satellite water clarity observations data. For a Two-Story lake, this is considered Excellent.
Upper Nashotah Lake was monitored by volunteers between 1988 and 1989. 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.
