Fish and Aquatic Life
Cornell Lake is a clear water lake with a diverse plant community. An aquatic plant survey would
assess the current state and condition of the plants in this lake, which would be valuable in
documenting the in-lake fisheries habitat and the existence of any introduced species that have

A hard water, seepage lake, with a small outlet stream flowing to O'Neil Creek. A one-foot high water control structure on the outlet is operated by Godfrey Robilard. Managed for bass and pan fish. Its fish population consists of northern pike, walleyes, perch, largemouth bass, bluegills, black crappies, rock bass, pumpkinseed, black bullheads, white suckers and redhorse. Carp are also common here and are considered a management problem. Over 190 acres of wetlands provide habitat for muskrat and nesting mallards and blue-winged teal. Public access consists of a one-acre town park on the west side of the lake and an additional access on a point adjacent to the park. There is also one
undeveloped platted access on the lake. Total public frontage amounts to .13 miles. There are two resorts, two boat rental places, 31 cottages and dwellings and a convalescent home on the lake shore.

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.

Cornell Lake is located in the McCann Creek and Fisher River watershed which is 311.06 mi². Land use in the watershed is primarily forest (39.20%), agricultural (22.90%) and a mix of wetland (22.10%) and other uses (15.80%). This watershed has 385.14 stream miles, 3,485.11 lake acres and 33,345.65 wetland acres.
Nonpoint Source Characteristics
This watershed is ranked Not Ranked for runoff impacts on streams, Not Ranked 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.
