Fish and Aquatic Life
Leggett Creek is a tributary to the Platte River in central Grant County. Seven miles of the creek are considered to be a class II trout stream (WDNR, 1980). Its uses are impaired by nonpoint source pollution. This stream is very flashy and water levels can rise very quickly during runoff events. Therefore, streambank erosion is a problem as well as cropland runoff. Intense grazing next to the stream also adds to the erosion problem. A headwaters reach of Leggett Creek was added to the state’s impaired streams list in 1998 due to problems resulting from nonpoint source pollution. Leggett was one of the southwest Wisconsin streams monitored as part of an intensive rotational grazing study (Lyons, et.al., 2000). There is landowner support for streambank stabilization and improvement projects on Leggett Creek. A species listed on the state’s threatened and endangered species list is found in Leggett Creek (Lyons, 2000).

A spring-fed stream beginning on the south slope of the Military Ridge two miles east of Fennimore and flowing southeast to enter the headwaters of the Platte River six miles west of Livingston. This stream is sometimes referred to as "Schuppner Branch." The upper section of this stream is quite narrow with very few pools and little instream cover. About one mile of the central portion near the mouth of Newell Creek is considered brown trout water. A very good population of smallmouth bass is found in the wide, sluggish pools in the lower reaches. A beaver dam impounds the stream one mile above the mouth. Muskrat, mink, and migratory waterfowl are frequently seen. Pollution from the Preston cheese factory has entered the stream by way of Newell Creek in the past. Improvement of the soil and water control practices in the area could greatly benefit this stream's warm and cold water fishery. Public access is provided by the Platte River and four bridge crossings. Two dwellings adjoin the stream.

Leggett Creek (WBIC 953900) was assessed during the 2018 listing cycle; new biological (macroinvertebrate and 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 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.

Leggett Creek is located in the Platte River watershed which is 197.74 mi². Land use in the watershed is primarily grassland (43.30%), agricultural (30.70%) and a mix of forest (19%) and other uses (7.00%). This watershed has 455.07 stream miles, 21.45 lake acres and 1,303.48 wetland acres.
Nonpoint Source Characteristics
This watershed is ranked Medium for runoff impacts on streams, Not Available 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.This water is ranked High Stream for individual Rivers based on runoff problems and the likelihood of success from project implementation.
