Fish and Aquatic Life
Perch Lake, Bass, in the Soft Maple and Hay Creeks Watershed, is a 18.16 acre lake that falls in Rusk County. This lake is managed for fishing and swimming and is currently considered impaired.

A soft water, drainage lake on a feeder to Devils Creek. The normal flow at the outlet is estimated at 0.7 cfs. The lake contains rainbow trout, largemouth bass, yellow perch, pumpkinseed, white suckers, and black bullheads. The shoreline is about evenly divided between upland hardwood and fresh meadow. The littoral bottom is about 95 percent muck with the remainder being mixed sand and gravel. Game is limited mainly to a few nesting ducks. There is no private development, as the entire lake is in Rusk County Forest land. There is one public access with limited parking on the east end of the lake, and a campground and picnicking area has recently been developed here by the county.

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 Soft Maple and Hay Creeks watershed which is 176.75 mi². Land use in the watershed is primarily forest (56.70%), wetland (19.20%) and a mix of agricultural (11.40%) and other uses (12.70%). This watershed has 266.14 stream miles, 1,050.89 lake acres and 14,185.57 wetland acres.
Nonpoint Source Characteristics
This watershed is ranked High for runoff impacts on streams, Low 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.
