Fish and Aquatic Life
Perch Lake, in the Shell Lake and Upper Yellow River Watershed, is a 17.43 acre lake that falls in Washburn County. This lake is managed for fishing and swimming and is currently not considered impaired.

Its fishery includes numerous slow-growing largemouth bass along with perch, bluegills, pumpkinseeds, and bullheads. A ten-acre wetland is located off the southeast shore and is made up of a fringe of cattails beyond which is a tamarack-leatherleaf bog. A narrow ridge along the southwest shore separates the lake from a tag alder swamp. The remaining shore is pine plantation and hardwood-covered upland with steeply sloping shore. Another smaller tag alder swamp lies in the northwest corner. Aquatic vegetation growth is abundant along shore. The littoral bottom is sand along the upland shore and muck off the wetlands. The lake water is dark brown stained. Forbearer use is small but mallards, teal and occasionally wood ducks nest here. Additional northern duck use is made of the lake in spring and fall. There is no private development on the immediate lakeshore and there is no public access or public frontage.
Author Surface Water Inventory Of Wisconsin
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.

Perch Lake is located in the Shell Lake and Upper Yellow River watershed which is 166.67 mi². Land use in the watershed is primarily forest (56.10%), agricultural (12.10%) and a mix of grassland (11%) and other uses (20.70%). This watershed has 118.54 stream miles, 5,764.04 lake acres and 9,834.60 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.
