Fish and Aquatic Life
Beaver Creek is a tributary to Dell Creek in Sauk County. The creek is classified as a Class II
trout stream and exceptional resource water (ERW). Agriculture, wetlands, woodlands and
residential sub-developments dominate land use along the creek. The WDNR owns about 380
acres of stream corridor near the confluence with Dell Creek. A survey conducted in 1995
found very low numbers of trout. The stream has problems with sediment and nutrient
loading from agriculture, development pressure, and lack of in-stream habitat. The stream has
limited in-stream habitat, which has an impact on the stream's potential to support more trout.
The stream, however, has high value for other wildlife including ruffed grouse, woodcock and

The Beaver Creek was assessed during the 2018 listing cycle; temperature data did not exceed the 2018 WisCALM listing thresholds for the Fish and Aquatic Life use. This water was meeting this designated use and not considered impaired. It was proposed that this water be identified as a new Category 2 water.

Beaver Creek (WBIC 1297300) was assessed during the 2018 listing cycle; new temperature 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.

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.

Beaver Creek is located in the Dell Creek watershed which is 133.73 mi². Land use in the watershed is primarily forest (43%), agricultural (36%) and a mix of suburban (9%) and other uses (12%). This watershed has 231.97 stream miles, 193.10 lake acres and 4,715.88 wetland acres.
Nonpoint Source Characteristics
This watershed is ranked High for runoff impacts on streams, Medium 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.
