Fish and Aquatic Life
Elk Creek is a Class I trout stream for nearly 14 miles above Elk Creek Lake and Class 11 for 3.6
miles below the lake. The Class I portion of Elk Creek is listed as an outstanding resource water
(ORW) in NR 102, Water Quality Standards for Wisconsin Surface Waters. The state's
antidegradation policy prohibits new point source discharges to ORWs unless the effluent water
quality is better than background water quality found in the stream.
In Elk Creek, polluted runoff contributes to the degradation of critical trout habitat. Significant
streambank erosion was identified in 1978 above the lake at 19 sites in Dunn County and 35 sites in
Chlppewa County. About 80 percent of the sites in Dunn County were stabilized by a Trout
Unlimited project. Several barnyards located on the stream degrade water quality and fishery
habitat. Cropping close to the streambank is also a problem. Elk Creek has the potential to
improve as an excellent trout fishery if polluted runoff is controlled. As with Big Elk Creek, the
tributaries to Elk Creek contribute sediment, which could be controlled with best management
practices (Dwoznik, Holzer) .
The Chippewa County portion of Elk Creek is designated as a State Fishery Area. WDNR has
acquired strearnbank easements and fenced the stream to protect the bank from erosion (Holzer).
Control of sources of polluted runoff, such as cropping close to streams, would benefit the majority
of Elk Creek's reaches.

Elk Creek (from the outlet of Elk Creek Lake upstream to the last crossing of the Dunn/ EauClaire county border) was assessed during the 2018 listing cycle; new biological (macroinvertebrate or 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. It was proposed that this water be identified as a new Category 2 water.

Elk Creek (from Chippewa/EauClaire boundary upstream to headwaters)was assessed during the 2018 listing cycle; new biological (macroinvertebrate or fish Index of Biotic Integrity (IBI) scores) sample data were clearly below the 2018 WisCALM listing thresholds for the Fish and Aquatic Life use. Temperature data also did not exceed thresholds. This water was meeting this designated use and was not considered impaired.

The Elk Creek (from mouth upstream to inlet of Elk Creek Lake) was assessed during the 2018 listing cycle; total phosphorus sample data overwhelmingly 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.

Elk Creek (2120800) from its mouth upstream to inlet of Elk Creek Lake was placed on the impaired waters list for total phosphorus in 2012. The 2016 assessments showed continued impairment by phosphorus; total phosphorus sample data exceeded 2016 WisCALM listing criteria for the Fish and Aquatic Life use, however, available biological data did not indicate impairment (i.e. no macroinvertebrate or fish Index of Biotic Integrity (IBI) scored in the "poor" condition category). Based on the most updated information, no change in existing impaired waters listing is needed.

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.

Elk Creek is located in the Muddy and Elk Creeks watershed which is 237.94 mi². Land use in the watershed is primarily agricultural (60%), forest (19%) and a mix of suburban (8%) and other uses (12%). This watershed has 313.30 stream miles, 590.92 lake acres and 11,999.60 wetland acres.
Nonpoint Source Characteristics
This watershed is ranked Medium for runoff impacts on streams, High 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.
