Fish and Aquatic Life
A medium hard water drainage lake having slightly alkaline, medium brown water of low transparency. Transparency at the time of survey on July 29, 1964 was affected by an algal bloom. There are seven inlet streams, none of which afford any practical boating use, and the outlet stream, which is navigable, and is tributary to Little Oxbow Lake and part of the Turtle River drainage. Sand is the predominant littoral material (50 percent) with gravel (35 percent), muck (10 percent) and some rubble. Upland shoreline is predominant (90 percent) with the balance being wetland of the shrub type and also some conifer. Muskellunge, northern pike, walleye, largemouth bass, smallmouth bass, perch, bluegill, black crappie, rock bass, pumpkinseed, bullhead, white sucker, and redhorse inhabit this lake. Black duck use this lake as a nesting site. Waterfowl use this lake on their spring and fall migrations. Muskrat and beaver are present. Floating and submergent vegetation varies from moderate to dense in the extreme upper portion of the lake basin. In the littoral areas floating and emergent vegetation is common. Approximately a half dozen islands within the lake basin add to the lake's aesthetic qualities. There are 72 dwellings and three resorts located on the shoreline. Public access with parking from an unimproved landing is available on the outlet stream just below the lake. Shallowness of the stream at this point limits use to relatively small craft. Access without parking from a county highway is also available. A temperature profile on July 29, 1964 revealed a surface temperature of 74 degrees Fahrenheit and a bottom temperature of 70 degrees Fahrenheit. Thermal stratification apparently does not occur.

Long Lake (2303500) was placed on the impaired waters list due to Mercury in fish tissue in 1998. This water is impaired for Fish Consumption use; a special consumption advisory is in effect for Long Lake. This water was assessed during the 2016 listing cycle; total phosphorus sample data were clearly below 2016 WisCALM listing thresholds for Recreation use and Fish and Aquatic Life use. Chlorophyll sample data were clearly below FAL use listing thresholds and did not exceed REC listing thresholds. This water is considered to be meeting both Recreation and Fish and Aquatic Life uses.

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.
Monitor Fish Tissue
Long Lake - Monitor for fish tissue.
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.

Long Lake is located in the Flambeau Flowage watershed which is 247.18 mi². Land use in the watershed is primarily forest (56.80%), wetland (28.20%) and a mix of open (14.10%) and other uses (0.90%). This watershed has 190.98 stream miles, 10,199.06 lake acres and 43,978.35 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.
