A soft water drainage lake having slightly alkaline light brown water of moderate transparency. Muck is the principal littoral material (55 percent) with sand (25 percent) and some gravel, rubble and boulders present. The shoreline is predominantly upland (80 percent) with a bog and meadow wetland bordering a portion of the lake basin. Floating and submergent vegetation are dense in parts of the lake basin. Fish species found in this lake are muskellunge, northern pike, walleye, largemouth bass perch, bluegill, crappie, pumpkinseeds and bullheads. Public access with parking is available. Two resorts and three dwellings are located on the shoreline. Black duck use this lake as a nesting site. Puddle ducks and diving ducks utilize this lake on their fall migration. At the time of survey an active beaver dam was located on the outlet.

Little Bearskin Lake (WBIC 1523500) was placed on the impaired waters list for total phosphorus in 2016. This lake was assessed during the 2018 listing cycle; new chlorophyll sample data were clearly below 2018 WisCALM listing thresholds for the Recreation use and the Fish and Aquatic Life use. Total Phosphorus sample data nearly exceeded the thresholds. Based on the most updated information, no change in the existing impaired waters listing was needed.

Little Bearskin Lake (1523500) was assessed during the 2016 listing cycle; total phosphorus sample data exceed 2016 WisCALM listing thresholds for the Recreation use, however, chlorophyll data do not exceed REC thresholds. Total phosphorus and chlorophyll data do not exceed Fish and Aquatic Life thresholds.

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.

This determination is based on one year (2017) with higher than average chlorophyll for the lake. This is not clear in any other year between 2009 and 2018.
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.

Little Bearskin Lake is located in the Middle Tomahawk River watershed which is 233.30 mi². Land use in the watershed is primarily forest (64.60%), wetland (26.90%) and a mix of open (7%) and other uses (1.50%). This watershed has 191.49 stream miles, 4,575.90 lake acres and 42,061.39 wetland acres.
Nonpoint Source Characteristics
This watershed is ranked Not Ranked for runoff impacts on streams, Low for runoff impacts on lakes and Low for runoff impacts on groundwater and therefore has an overall rank of Low. 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.
