Fond Du Lac
Fish and Aquatic Life
Buttermilk Lake, in the East and West Branches Milwaukee River Watershed, is a 13.24 acre lake that falls in Fond du Lac County. This lake is managed for fishing and swimming and is currently not considered impaired.

A small hard water seepage lake which has an intermittent marshy connection with neighboring Spring Lake. Its shallow depth and abundance of aquatic vegetation probably cause annual winterkill conditions, and limits the fishery primarily to bullheads and minnows. The lake has a predominantly muck bottom and most of the shoreline is wooded. No dwellings are located on or near the shoreline. An unimproved access is provided by the 0.13 miles of public frontage on its east shore which lies within the present boundary of the northern unit of the Kettle Moraine State Forest.
Mallard ducks have been observed to raise broods here and other waterfowl visit the lake during seasonal migrations. The wild setting and clear water of this lake during seasonal migrations. The wild setting and clear water of this lake qualifies its classification as a wilderness type lake, and efforts should be made to preserve it as such.

Wisconsin has over 84,000 miles of streams, 15,000 lakes and milllions of acres of wetlands. Assessing the condition of this vast amount of water is challenging. The state's water monitoring program uses a media-based, cross-program approach to analyze water condition. An updated monitoring strategy (2015-2020) is now available. Compliance with Clean Water Act fishable, swimmable standards are located in the Executive Summary of Water Condition in 2018. See also the 'monitoring and projects' tab.
Wisconsin's Water Quality Standards provide qualitative and quantitative goals for waters that are protective of Fishable, Swimmable conditions [Learn more]. Waters that do not meet water quality standards are considered impaired and restoration actions are planned and carried out until the water is once again fishable and swimmable
Management goals can include creation or implementation of a Total Maximum Daily Load analysis, a Nine Key Element Plan, or other restoration work, education and outreach and more. If specific recommendations exist for this water, they will be displayed below online.
Monitoring the condition of a river, stream, or lake includes gathering physical, chemical, biological, and habitat data. Comprehensive studies often gather all these parameters in great detail, while lighter assessment events will involve sampling physical, chemical and biological data such as macroinvertebrates. Aquatic macroinvertebrates and fish communities integrate watershed or catchment condition, providing great insight into overall ecosystem health. Chemical and habitat parameters tell researchers more about human induced problems including contaminated runoff, point source dischargers, or habitat issues that foster or limit the potential of aquatic communities to thrive in a given area. Wisconsin's Water Monitoring Strategy was recenty updated.

Buttermilk Lake is located in the East and West Branches Milwaukee River watershed which is 266.00 mi². Land use in the watershed is primarily agricultural (35.50%), wetland (19.20%) and a mix of forest (17.90%) and other uses (27.40%). This watershed has 312.44 stream miles, 2,023.13 lake acres and 32,107.47 wetland acres.
Nonpoint Source Characteristics
This watershed is ranked High for runoff impacts on streams, High for runoff impacts on lakes and High for runoff impacts on groundwater and therefore has an overall rank of High. This value can be used in ranking the watershed or individual waterbodies for grant funding under state and county programs.However, all waters are affected by diffuse pollutant sources regardless of initial water quality. Applications for specific runoff projects under state or county grant programs may be pursued. For more information, go to surface water program grants.
