Historical Description
Source: 1969, Surface Water Resources of Sawyer County Black Dan Lake, T39, 40, R5W, Section 36, 1
A hard water, drainage lake on the headwaters of Island Creek. The estimated outlet flow is 0.5 cfs. Fish species include walleyes, muskellunge, largemouth bass and panfish. About 60 percent of the lakeshore is steep, sloped and much of the remaining lake edge is spruce bog. The wetland area provides some nesting for ducks and muskrat are common here. The lakeshore, not bordered by wetlands, is mostly coarse gravel. There is a public access with limited parking near the outlet and public frontage amounts to 0.02 miles of Dept. of Natural Resources island frontage. Private development on the lake includes two resorts and boat rentals and 21 cottages.

General Condition
Black Dan Lake (Mcdonald) (2381900) 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.

Condition
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.

Management Goals
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
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.

Watershed Characteristics
Black Dan Lake is located in the Weirgor Creek and Brunet River watershed which is 324.00 mi². Land use in the watershed is primarily forest (64.80%), wetland (24.80%) and a mix of agricultural (4.10%) and other uses (6.40%). This watershed has 407.41 stream miles, 2,240.99 lake acres and 39,377.08 wetland acres.
Nonpoint Source Characteristics
This watershed is ranked Low 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.
