Overview
Grant Lake is a soft water drainage lake having slightly acid, medium brown water of low transparency. There is an inlet stream from North Grant Lake and the outlet is tributary to the Flambeau Flowage. Sand is the predominant littoral material (45 percent) with muck (35 percent), rubble (10 percent) and some gravel and boulders. The shoreline is predominantly upland (70 percent) with the balance being wetland of the bog and coniferous type with same meadow and shrub. Muskellunge, northern pike, walleye, largemouth bass, perch, bluegill, black crappie, pumpkinseed, black bullhead, white sucker, and redhorse are fish inhabiting this lake. Waterfowl use this lake on their spring and fall migrations and probably for nesting, particularly mallard and black duck. Emergent and submergent vegetation are moderate in density in one-quarter of the lake basin with floating vegetation sparse. Beaver are present. There are 11 dwellings and one resort located on the shoreline. There is no public access. At the time of survey, beaver had effectively dammed both the inlet and outlet streams, causing little or no flow to occur.

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
Grant Lake is located in the Flambeau Flowage watershed which is 247.18 mi². Land use in the watershed is primarily forest (56.80%), wetland (28.20%) and a mix of open (14.10%) and other uses (0.90%). This watershed has 190.98 stream miles, 10,199.06 lake acres and 43,978.35 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.
