Fish and Aquatic Life
This trout stream has a number of sources of polluted runoff that degrade the aquatic habitat. A
1994 stream survey indicated that improvement of the in-stream habitat of Thompson Valley Creek
would benefit the trout by providing cover and increase winter survival of stocked trout (Kurz).
Bush Bros. operates a spray irrigation field on land adjacent to the creek. At similar sites, slime and
iron precipitates have been observed in the streambed due to sub-surface movement of the waste
into the stream. In recognition of past problems, a visual examination of the stream is necessary to
determine if there are signs of excessive loading (LaLiberte 1994)

The Thompson Valley Creek (From mouth to CTH R on west side of S6, T25N, R6W) 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). Temperature data did not exceed thresholds. This water was not meeting this designated use and is considered impaired. No listing change was needed to this already impaired water.

Thompson Valley Creek (WBIC 2131100) from headwaters to second crossing of Hwy R was listed for total phosphorus and elevated water temperature in 2014. This water was assessed during the 2018 listing cycle; new biological (fish Index of Biotic Integrity (IBI) scores) sample data were clearly below 2018 WisCALM listing thresholds for the Fish and Aquatic Life use. The 2018 assessments showed continued impairment by temperature; new temperature sample data exceeded 2018 WisCALM listing criteria for the Fish and Aquatic Life use. Based on the most updated information, no change in the existing impaired waters listing was needed.

Thompson Valley Creek (2131100) from headwaters to second crossing of Hwy R was assessed during the 2016 listing cycle; temperature data exceeded 2016 WisCALM listing thresholds for the Fish and Aquatic Life use.

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'.
Citizen-Based Stream Monitoring
Collect chemical, physical, and/or biological water quality data to assess the current overall stream health. The data can inform management decisions and may be used to identify impaired waters for biennial lists.
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.

Thompson Valley Creek is located in the Lower Eau Claire River watershed which is 216.31 mi². Land use in the watershed is primarily agricultural (47%), forest (37%) and a mix of suburban (6%) and other uses (10%). This watershed has 414.24 stream miles, 937.46 lake acres and 10,770.45 wetland acres.
Nonpoint Source Characteristics
This watershed is ranked Not Available 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.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.
