One-mile Creek is a tributary to the Lemonweir below Mauston. About 9.5 miles of its length are trout waters, five miles of Class I, two miles of Class II, and 2.5 miles of Class III. The Class I portion is also considered an Exceptional Resource Water (ERW). Sedimentation is causing in-stream habitat problems in some reaches. Cattle grazing adjacent to the stream is a source of the problem. Sediment from tributaries is also thought to be contributing to the problem. One-mile Creek is considered a high priority for a small-scale nonpoint source pollution reduction project. The WDNR has purchased some easements along this stream.

Onemile Creek is a tributary to the Lemonweir below Mauston. About 9.5 miles of its
length are trout waters, five miles Class 1, two miles of Class II, and 2.5 miles of Class III
(WDNR, 1980). The Class I portion is also considered exceptional resource waters
under the state's antidegradation rules. Sedimentation is causing in-stream habitat
problems in some reaches. Cattle grazing adjacent to the stream are a source of the
problem (Ironside, 1991). Sediment from tributaries are also thought to be
contributing to the problem (WDNR, 1991).

The Onemile Creek (Mouth to US 12) was assessed during the 2018 listing cycle; total phosphorus sample data clearly exceeded the 2018 WisCALM listing thresholds for the Fish and Aquatic Life use. Available biological data did not indicate impairment (i.e. no macroinvertebrate or fish Index of Biotic Integrity (IBI) scored in the "poor" condition category). This water was not meeting this designated use and was considered impaired. No listing change was needed to this already impaired water.

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 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.

Onemile Creek is located in the Lower Lemonweir River watershed which is 209.62 mi². Land use in the watershed is primarily forest (36.20%), agricultural (31%) and a mix of wetland (22.30%) and other uses (10.60%). This watershed has 384.35 stream miles, 558.61 lake acres and 17,722.41 wetland acres.
Nonpoint Source Characteristics
This watershed is ranked Medium for runoff impacts on streams, Low 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.
