Fish and Aquatic Life
The South Branch Pigeon River has its origin in south central Shawano County. The river is dammed in Waupaca County, forming 20-acre Keller Lake. The watershed is principally wetland and forested above Keller Dam and agricultural below. The stream suffers habitat deterioration from streambank pasturing and cropland runoff, although the severity varies from year to year as crops are rotated.

South Branch Pigeon River (Mile 14.59 to 19.49) was assessed during the 2018 listing cycle; new total phosphorus, biological (macroinvertebrate and fish Index of Biotic Integrity (IBI) scores), and temperature sample data were clearly below 2018 WisCALM listing thresholds for the Fish and Aquatic Life use. This water was meeting this designated use and was not considered impaired. Based on the most recent total phosphorus and temperature data, this water was being proposed as a Category 2.

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.

South Branch Pigeon River is located in the Pigeon River watershed which is 116.32 mi². Land use in the watershed is primarily agricultural (47%), forest (27%) and a mix of wetland (17%) and other uses (9%). This watershed has 146.47 stream miles, 197.04 lake acres and 15,030.25 wetland acres.
Nonpoint Source Characteristics
This watershed is ranked Medium for runoff impacts on streams, High for runoff impacts on lakes and Low for runoff impacts on groundwater and therefore has an overall rank of Low. 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.
