Fish and Aquatic Life
The Cornell Flowage, about four miles downstream of Holcombe Flowage, exhibits weak
stratification. Moderate algae blooms were present in August, 1989. Anoxic bottom conditions have
not been found on any observation dates. The Trophic State Index value of 56-58 indicates poor
water quality conditions OJVDNR Oct. 1993). Brunet Island State Park is located w i t h the Cornell
Flowage at the mouth of the Fisher River.

main stem section of ths plan.

A soft water, drainage impoundment on the Chippewa River. It has a 39-foot public utility dam (Northern States Power Co.) on its outlet. Its most common fish species are walleyes, black crappies and redhorse. Other fish species present in this flowage include northern pike, muskellunge, largemouth and smallmouth bass, Perch, bluegills, rock bass, pumpkinseeds, channel catfish, brown bullheads, rock sturgeon, burbot, white suckers and quillback. A problem in the management of this flowage is the fluctuating water levels. Over 150 acres of wetlands provide habitat for muskrat, beaver, nesting mallards, teal, wood ducks and mergansers. Additional numbers of migratory puddle and diving ducks and coots use the flowage as a resting place, in the spring and fall. Public frontage on the Cornell Flowage amounts to 5.18 miles of state-owned frontage. Brunet Island State Park (222 acres) is located on the flowage and offers camping facilities, swimming beaches, and access roads. Another access to the flowage is located in its upper part one-half mile south of the Holcombe Dam off the town road. Private development consists of five cottages and a boat rental place. A small feeder stream flowinginto Cornell Flowage that is not mentioned elsewhere in the summary is located in Section 31. Its fish species are limited to forage minnows.

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 Flowage 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.
