Marquette County, 341 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 48 (Mesotrophic) and was determined using satellite water clarity observations data. For a Reservoir lake, this is considered Excellent.
Lake Montello was monitored by volunteers between 1988 and 1990. 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 Lake Grants. Reports and graphs featuring data collected by volunteers, DNR staff and others can be viewed below.
