Fish and Aquatic Life
Knapp Creek, located in north central Vernon County, flows in a south westerly direction for 4.0 miles before reaching the West Fork of the Kickapoo River north of Bloomingdale. This stream has a gradient of 34 feet per mile and drains forested hillsides and agricultural valleys and an agricultural headwater plateau. Knapp Creek is a Class III trout stream for its entire length.

Knapp Creek, T14N, R3W, Section 30. Surface Acres = 4.1, Miles = 4.0, Gradient = 34.2 feet per mile.
A clear, hard water stream that flows in a southwesterly direction and is a tributary of the West Fork Kickapoo River. It is Class III brown trout water. Forage fish include white suckers, creek chubs, hog suckers and redside dace. Though rubble is the dominant bottom type, there is considerable sand, and small amounts of silt and gravel. One road crossing provides access. Muskrat are significant and beaver are present. Wood ducks nest along the stream and migrant dabbler ducks use the water.

Knapp Creek was assessed during the 2018 listing cycle; new biological (fish Index of Biotic Integrity (IBI) scores) sample data were clearly below 2018 WisCALM listing thresholds for the Fish and Aquatic Life use. 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 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.

Knapp Creek is located in the West Fork Kickapoo River watershed which is 118.04 mi². Land use in the watershed is primarily agricultural (56%), forest (37%) and a mix of suburban (5%) and other uses (1%). This watershed has 283.75 stream miles, 49.18 lake acres and 672.36 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.
