A soft water, drainage lake on the Couderay River. It has an estimated normal outlet flow of 27.0 cfs. The fish population consists of muskellunge, northern pike, walleye, largemouth and smallmouth bass, abundant panfish and cisco. Lake trout and brook trout are present in only small numbers. Rough fish and minnows found here include white suckers, redhorse, longnose gar, golden shiners, and creek chubs. Black spruce bog is found along 10 percent of the lakeshore and the remaining shore vegetation is upland hardwood and pine. The extensive stands of rooted and floating vegetation provides additional habitat for nesting ducks and a large number of other migratory waterfowl. Beaver and muskrat are also present. Private development consists of one resort and 21 cottages. It is accessible off the town road crossing the inlet from Lac Court Oreilles Lake and public frontage amounts to 0.07 miles of frontage at four undeveloped platted access sites. A small unnamed feeder stream flowing into the lake from the east is brook trout water.

Little Lac Courte Oreilles (2390500) was assessed during the 2016 listing cycle; total phosphorus and chlorophyll sample data were clearly below Fish and Aquatic Life use listing thresholds. This water is meeting this designated use 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.
Shoreland Monitoring, Assessment, Inventory
Courte Oreilles Lake Association is sponsoring a project to design and install shoreline buffer restorations on Lac Courte Oreilles and Little Lac Courte Oreilles Lakes. Project tasks include: 1) Shoreline buffer design/restoration on approximately 25 shoreline sites; 2) Modeling to estimate TSS and TP reductions from buffer restorations; 3) Develop and distribute shoreline buffer educational materials.
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.

Little Lac Courte Oreilles is located in the Couderay River watershed which is 212.25 mi². Land use in the watershed is primarily forest (64.90%), wetland (13.50%) and a mix of open (12.90%) and other uses (8.70%). This watershed has 211.96 stream miles, 18,300.76 lake acres and 14,697.69 wetland acres.
Nonpoint Source Characteristics
This watershed is ranked Low for runoff impacts on streams, High 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.
