Fish and Aquatic Life
Island Lake, in the Upper St. Croix and Eau Claire Rivers Watershed, is a 63.05 acre lake that falls in Bayfield County. This lake is managed for fishing and swimming and is currently not considered impaired.

This landlocked, soft water, seepage lake is populated by largemouth bass cisco, bluegill, black crappie, and pumpkinseed. The entire lake is surround by wooded upland, and the littoral bottom is 100 percent sand. Because of a lack of wetlands, wildlife values are limited. The entire lake shore is privately owned and lies within the Potawatomi Estates. All the land around the lake has been subdivided and is being sold as lots to private individuals. Three platted accesses have been provided on the lake with the one on the southwest corner of the lake the only one that is presently developed and useable. Private development consists of several storage buildings on the island peninsula and three cottages. The three platted accesses provide the only public frontage.

Island Lake (2470800) was assessed during the 2016 listing cycle; total phosphorus sample data were clearly below 2016 WisCALM listing thresholds for the Recreation use and Fish and Aquatic Life use. Chlorophyll data did not exceed REC or FAL listing thresholds. This water is meeting these designated uses and is 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.

Island Lake is located in the Upper St. Croix and Eau Claire Rivers watershed which is 277.89 mi². Land use in the watershed is primarily forest (83.90%), wetland (9.50%) and a mix of open (4.30%) and other uses (2.40%). This watershed has 153.93 stream miles, 7,654.41 lake acres and 13,694.48 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.
