Fish and Aquatic Life
Porcupine Lake, in the Brule River Watershed, is a 36.02 acre lake that falls in Florence County. This lake is managed for fishing and swimming and is currently not considered impaired.

A very soft water seepage lake having acid, clear water of moderate transparency. Littoral materials are composed of sand (50 percent) and muck (50 percent). The shoreline is 80 percent upland consisting of hardwoods, conifers and cleared land with the balance being bog and coniferous wetland. Fish species inhabiting this lake are largemouth bass, perch, bluegill and black crappie. Waterfowl make limited use of this lake. The wilderness type public access exists across U. S. Forest Service land from a road three-fourths of a mile east of the lake. Fourteen dwellings are located on the shoreline.

Porcupine Lake (WBIC 590800) was assessed during the 2018 listing cycle; new total phosphorus and chlorophyll-a sample data were clearly below the 2018 WisCALM listing thresholds for the Recreation use and the Fish and Aquatic Life use. This water was meeting these designated uses and was not considered impaired.

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.

Porcupine Lake is located in the Brule River watershed which is 194.73 mi². Land use in the watershed is primarily forest (76.50%), wetland (17.70%) and a mix of grassland (2.90%) and other uses (2.80%). This watershed has 192.50 stream miles, 2,169.69 lake acres and 13,322.90 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.
