Overview
Slim Creek Flowage, in the Brill and Red Cedar Rivers Watershed, is a 105.84 acre lake that falls in Washburn County. This lake is managed for fishing and swimming and is currently not considered impaired.

Historical Description
A hard water, drainage impoundment on Slim Creek, two miles upstream from the creek's outlet to the north end of Long Lake. The Slim Creek dam has a head of 12 feet and was built in 1936 for Washburn County as a W.P.A. project. The estimated normal flow of the outlet is 1.6 cubic
feet per second. The fishery is made up of northern pike, largemouth bass, slow growing bluegills, pumpkinseeds, bullheads and a few walleyes. The latter species occasionally emigrate down from Slim Lake. The flowage is V-shape d with two arms pointing towards the outlet dam. Slim Creek
flows into the South arm. The north arm is deeper since a small, natural lake was flowed when the dam was installed. The Shoreline is almost entirely upland with mixed hardwood and pine cover. A small bog lies adjacent to the south arm near the outlet. Aquatic vegetation growth is abundant and varied in species composition. The bottom type is mostly sand, 65 percent, with 5 percent gravel and 30 percent muck, found in the large shallow bays of the north arm. Beaver are active here and muskrats are common as well as nesting puddle ducks and loon. There are four cottages on the west shore. Of the lake's 4.3 miles of shoreline, 3 miles of frontage is Washburn County Forest land. A public access and small picnic area is located near the dam.

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
Slim Creek Flowage is located in the Brill and Red Cedar Rivers watershed which is 297.68 mi². Land use in the watershed is primarily forest (49.40%), agricultural (20.30%) and a mix of grassland (10.70%) and other uses (19.60%). This watershed has 264.90 stream miles, 6,282.34 lake acres and 15,832.05 wetland acres.
Nonpoint Source Characteristics
This watershed is ranked Medium for runoff impacts on streams, Medium 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.
