Fish and Aquatic Life
Birch Island Lake, in the Lower Namekagon River Watershed, is a 768.03 acre lake that falls in Burnett County. This lake is managed for fishing and swimming and is currently not considered impaired.

A landlocked, soft water, seepage lake which is subject to periodic winterkills, the last one occurring during the winter of 1964- 1965. Fish species present are northern pike, largemouth bass, bluegill, black crappie, perch, pumpkinseed, bullhead and bowfin. It is an excellent waterfowl lake and has high use by migratory scaup, mallards, ring-necked ducks, widgeon, coots and occasional goldeneyes and geese. The 420 acres of adjoining wetlands provide habitat for nesting mallards, blue-winged teal, wood ducks, ring-necked ducks and loons. Eighty percent of the littoral zone is sand bottomed and there is a moderate amount ofaquatic vegetation. About 20 percent of the predominantly upland shoreline is pastured. Private development consists of 46 cabins. The only public frontage is 0.82 miles around the state-owned island. There is no public access.

Birch Island Lake (2453500) was assessed during the 2016 listing cycle; total phosphorus and chlorophyll sample data were clearly below 2016 WisCALM listing thresholds for the Recreation use and Fish and Aquatic Life use. This water is meeting these designated uses and is not considered impaired.

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.

Birch Island Lake is located in the Lower Namekagon River watershed which is 239.34 mi². Land use in the watershed is primarily forest (73.10%), wetland (15.20%) and a mix of open (7.40%) and other uses (4.40%). This watershed has 172.53 stream miles, 12,590.30 lake acres and 21,781.64 wetland acres.
Nonpoint Source Characteristics
This watershed is ranked Not Ranked for runoff impacts on streams, Not Ranked 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.
