Natural Community
Natural communities (stream and lake natural communities) represent model results that use predicted flow and temperature based on landscape features and related assumptions. Ranges of flow and temperature associated with specific aquatic life communities (fish, macroinvertebrates) help biologists identify appropriate resource management goals.

Trout Water 
Trout Waters are represented by Class I, Class II or Class III waters. These classes have specific ecological characteristics and management actions associated with them. For more information regarding Trout Classifications, see the Fisheries Trout Class Webpages.
No
Outstanding or Exceptional 
Wisconsin has designated many of the state's highest quality waters as Outstanding Resource Waters (ORWs) or Exceptional Resource Waters (ERWs). Waters designated as ORW or ERW are surface waters which provide outstanding recreational opportunities, support valuable fisheries and wildlife habitat, have good water quality, and are not significantly impacted by human activities. ORW and ERW status identifies waters that the State of Wisconsin has determined warrant additional protection from the effects of pollution. These designations are intended to meet federal Clean Water Act obligations requiring Wisconsin to adopt an 'antidegradation' policy that is designed to prevent any lowering of water quality - especially in those waters having significant ecological or cultural value.
No
Impaired Water 
A water is polluted or 'impaired' if it does not support full use by humans, wildlife, fish and other aquatic life and it is shown that one or more of the pollutant criteria are not met.
No

Current Use
The use the water currently supports. This is not a designation or classification; it is based on the current condition of the water. Information in this column is not designed for, and should not be used for, regulatory purposes.
Impounded Flowing Water
This classification includes waterbodies created by dams (mill ponds, reservoirs, flowages, and other impoundments) with a residence time of 14 days or more (under summer (June – Sept) mean low flow conditions with a 1 in 10 year recurrence interval (US EPA 2000)). Many natural lakes also have dams or water level control structures. However, to be included in the Impounded Flowing Waters category, the dam or water level control structure, must account for more than half of a waterbody’s maximum depth. Impoundments with a residence time of less than 14 days should be covered under the rivers and stream assessment methodology process.
Attainable Use
The use that the investigator believes the water could achieve through managing "controllable" sources. Beaver dams, hydroelectric dams, low gradient streams, and naturally occurring low flows are generally not considered controllable. The attainable use may be the same as the current use or it may be higher.
FAL
Fish and Aquatic Life - waters that do not have a specific use designation subcategory assigned but which are considered fishable, swimmable waters.
Designated Use
This is the water classification legally recognized by NR102 and NR104, Wis. Adm. Code. The classification determines water quality criteria and effluent limits. Waters obtain designated uses through classification procedures.
Default FAL
Fish and Aquatic Life - Default Waters do not have a specific use designation subcategory but are considered fishable, swimmable waters.

Overview

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.

Historical Description

Source: 1963, Surface Water Resources of Chippewa County Cornell Flowage T31, 32N, R6, 7W, Sections 6, 7, 18, 13, 12, 32, 29, and 28

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.

General Condition

Brunet Island State Park Beach was assessed for the 2018 listing cycle; E. coli data sample data were clearly below the 2018 WisCALM listing thresholds for the Recreation use. This beach was meeting this designated use and was not considered impaired.

Condition

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 2016 . See also 'monitoring' and 'projects'.

Management Goals

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 and implementation of a Total Maximum Daily Load Analysis, habitat restoration work, partnership education and outreach and more. If specific recommendations exist for this water, they will be displayed below.

Monitoring

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.

Watershed Characteristics

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%), agricultural (35%) and a mix of wetland (13%) and other uses (13%). 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.

Natural Community

Brunet Island State Park Beach is considered a Impounded Flowing Water under the state's Natural Community Determinations.
