White Ash 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 65 (Eutrophic) and was determined using chlorophyll data. For a Shallow Lowland lake, this is considered Fair. Shallow Lowland lakes do not stratify, or form separate layers of water, during the summer months and have watersheds greater than 4 square miles in area.

White Ash Lake was monitored by volunteers between 1993 and 2022. 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. Reports and graphs featuring data collected by volunteers, DNR staff and others can be viewed below.
