Fish and Aquatic Life
Coon Valley Creek is a spring-fed tributary to Fennimore Fork that supports some natural reproduction of brook trout. The lower 2.3 miles of the creek are considered Class II trout waters while the one mile above Homer Road is a Class I trout fishery. Nonpoint source pollution from streambank erosion and pasturing is a severe threat.

From: Smith, Tom D., and Ball, Joseph R., Lake and Stream Classification Project. Surface Water Resources of Grant County, Department of Natural Resources, 1972.Surface Area = 2.20 acres, Length = 3.3 miles, Gradient = 37 ft./mile, Flow = 2.1 c.f.s.
A spring-fed tributary of Fennimore Fork entering from the west fqur miles above the junction with the Blue River. The upper portions of this stream are badly eroded and siltation is heavy in the lower half.
Trout water stretches three miles upstream from the mouth. Brown trout provide the major fishery with rainbows being present. Mayfly, caddis fly, freshwater shrimp, and crayfish are common to abundant. A dry structure is planned on the upper reaches as part of the Blue River P.L. 566 Watershed Project. This structure will positively lessen the erosion and siltation problems which are detrimental to the fishery. Upland game species are found in the surrounding hills while muskrats inhabit the stream. Access is possible from one bridge crossing, Fennimore Fork, and a road paralleling the stream along most of its length. Four farm dwellings are found along the banks.

Coon Valley creek (1211700), from the mouth to Homer Rd., was assessed during the 2018 listing cycle; new biological (fish Index of Biotic Integrity (IBI) scores) sample data were clearly below the 2018 WisCALM listing thresholds for the Fish and Aquatic Life use. This water was meeting this designated use and was 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 2016 . See also 'monitoring' and 'projects'.
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 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.

Coon Valley Creek is located in the Blue River watershed which is 216.19 mi². Land use in the watershed is primarily agricultural (51%), forest (37%) and a mix of suburban (5%) and other uses (6%). This watershed has 513.46 stream miles, 416.83 lake acres and 5,825.06 wetland acres.
Nonpoint Source Characteristics
This watershed is ranked High 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.
