Rocky Run, in the South Fork Eau Claire River Watershed, is a 7.97 mile river that falls in Clark County. This river is managed for fishing and swimming and is currently not considered impaired.

Rocky Run T27N, R3 W, S26, Surface Acres 9.0, Miles = 6.2.
A clear, medium hard water stream that flows south and then west into the south
fork of the Eau Claire River. It appears to have a high gradient. Smallmouth bass
and panfish comprise the sport fishery. Of the total watershed area, about
73 percent of the land has been cleared. There are no public lands adjoining
the creek. Access is possible from five road crossings.

The 2018 assessments of Rocky Run showed impairment by phosphorus; new total phosphorus sample data exceeded the 2018 WisCALM listing criteria for the Fish and Aquatic Life use. However, available biological data did not indicate impairment (i.e. no macroinvertebrate Index of Biotic Integrity (IBI) scored in the "poor" condition category). Based on the most updated information, this water was proposed for the impaired waters list.

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.

Rocky Run is located in the South Fork Eau Claire River watershed which is 229.49 mi². Land use in the watershed is primarily forest (56%), agricultural (22.80%) and a mix of wetland (12%) and other uses (9.20%). This watershed has 421.59 stream miles, 307.67 lake acres and 23,719.61 wetland acres.
Nonpoint Source Characteristics
This watershed is ranked Low for runoff impacts on streams, High for runoff impacts on lakes and Medium for runoff impacts on groundwater and therefore has an overall rank of Medium. 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.
Rocky Run is considered a Cool-Cold Headwater, Macroinvertebrate under the state's Natural Community Determinations.
Natural communities (stream and lake natural communities) represent model resultsand DNR staff valiation processes that confirm or update predicted conditions based on flow and temperature modeling from historic and current landscape features and related variables. Predicated flow and temperatures for waters are associated predicated fish assemblages (communities). Biologists evaluate the model results against current survey data to determine if the modeled results are corect and whether biological indicators show water quaity degradation. This analysis is a core component of the state's resource management framework. Wisconsin's Riverine Natural Communities.
Cool (Cold-Transition) Headwaters are small, usually perennial streams with cold to cool summer temperatures. Coldwater fishes are common to uncommon (<10 per 100 m), transitional fishes are abundant to common, and warm water fishes are uncommon to absent. Headwater species are abundant to common, mainstem species are common to absent, and river species are absent.
