Fish and Aquatic Life
The South Branch Oconto River joins the North Branch Oconto River near Suring to form the Oconto River. The watershed is primarily forested with limited agricultural activity. It has a total river length of 15 miles, with a surface area of 72.7 acres and an average width of 40 feet. The South Branch of the Oconto River Fishery Area was created in 1961 and to date
over 450 acres of land bordering the river has acquired by the Department of Natural Resources. The purpose of the fishery area is to perpetuate the native trout population, provide access for anglers and improve overall trout and wildlife habitat. Over 11 miles of the South Branch of the Oconto river flows through the fishery area.

The South Branch Oconto River was assessed during the 2018 listing cycle; new temperature sample data were clearly below 2018 WisCALM listing thresholds for the Fish and Aquatic Life use. This water is meeting this designated use and is 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.

South Branch Oconto River is located in the South Branch Oconto River watershed which is 219.27 mi². Land use in the watershed is primarily forest (56%), wetland (26%) and a mix of agricultural (8%) and other uses (10%). This watershed has 216.92 stream miles, 2,812.48 lake acres and 20,277.98 wetland acres.
Nonpoint Source Characteristics
This watershed is ranked Low for runoff impacts on streams, Not Ranked 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.
