Fish and Aquatic Life
Sedimentation from past and present surrounding landuse and possible extirpation of native cold water species. The dam that forms Rock Falls Pond acts as a barrier that would prevent salmonid species from migrating upstream. Fish management recommended declassifying this segment as trout water due to warm temperatures. Temperature data from 2000 suggests cold water is found upstream from this reach.

Rock Creek (miles 0-2.54) 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.

Sedimentation from past and present surrounding landuse and possible extirpation of native cold water species. The dam that forms Rock Falls Pond acts as a barrier that would prevent salmonid species from migrating upstream. Fish management recommended declassifying this segment as trout water due to warm temperatures. Temperature data from 2000 suggests cold water is found upstream from this reach. Fish and habitat surveys were completed at six stations and continuous temperature monitoring was completed at four stations in 2000 throughout Rock Creek Cold water IBI scores were poor to very poor and habitat ratings were fair to good. Continuous monitoring indicated that temperatures were adequate for cold water species, especially in the mid to upper reaches. Fish surveys were completed in 2006 at three sites above the Rock Falls Pond. One brown trout was found at the station just above the pond and no other cold water species were collected at the remaining sites.

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'.
This water, from the mouth to STH 85 (2.4 miles) is a Class II Troutwatwer; and the portion in Eau Claire County is a Class III. (4.0 miles).

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.

Rock Creek is located in the Lowes and Rock Creeks watershed which is 219.17 mi². Land use in the watershed is primarily agricultural (38.80%), forest (34.30%) and a mix of grassland (13.50%) and other uses (13.40%). This watershed has 372.30 stream miles, 317.07 lake acres and 12,231.21 wetland acres.
Nonpoint Source Characteristics
This watershed is ranked Low 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.
