Fish and Aquatic Life
Bahr Lake is a hard water seepage lake having alkaline, clear water of moderate transparency. The littoral zone is composed of muck. Approximately 90 percent of the shoreline is wetland consisting of hardwoods, conifers and shrub with the balance being cleared upland. Fish species found in this lake are northern pike, largemouth bass, bluegill, black bullhead, rainbow trout, and forage species. Present management of this lake is for trout. Information on wildlife values is lacking; however, limited use by waterfowl can be anticipated.
The only means of public access is by navigating the channel between Bahr and Korth Lakes. An intermittent outlet, Creek 8-11 (T27N, R17E), can be found on the southwest shore which flows to Duchess Creek. There is one dwelling located on the shoreline. This lake has been chemically treated twice to eradicate the warmwater fish population, however, reinfestation or incomplete kills have occurred.

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.

Bahr Lake is located in the Shawano Lake watershed which is 71.16 mi². Land use in the watershed is primarily forest (28.60%), agricultural (22%) and a mix of wetland (19.50%) and other uses (29.90%). This watershed has 76.28 stream miles, 7,438.74 lake acres and 7,573.91 wetland acres.
Nonpoint Source Characteristics
This watershed is ranked Not Ranked 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.
