Fish and Aquatic Life
Primrose Branch is a tributary to the West Branch Sugar River. Approximately 2.0 miles of its 5.0 mile length as classified as Class II trout waters. The remaining portion is classified as warm water sport fishery. The stream was surveyed in 1997 and 2002. Self-sustaining populations of brook trout were found in the stream. The stream would benefit from some habitat rehabilitation.

Primrose Branch -T5N, R7E, Sec. 14, Surface acres = 1.8, Length = 5 miles, Stream order = II, Gradient = 19.4 ft/mile, Base discharge = 2.8 cfs,
Primrose Branch drains 3 square miles of fertile cropland, pasture land, and upland and swamp hardwoods in Primrose Township. Its flow is augmented by at least 5 springs on its way to joining the West Branch of the Sugar River. Primrose Branch is a Class II trout stream supporting a wild trout population in its middle portion. Brown and brook trout are stocked. Five road crossings provide public access. Fish species: brown, brook, and rainbow trout, white sucker, and brook stickleback.

Primrose Branch was assessed during the 2018 listing cycle; new biological (fish Index of Biotic Integrity (IBI) scores) and 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.

Primrose Br is located in the West Branch Sugar River - Mt. Vernon Cre watershed which is 66.74 mi². Land use in the watershed is primarily agricultural (70%), forest (19%) and a mix of suburban (6%) and other uses (4%). This watershed has 156.64 stream miles, 9.41 lake acres and 1,131.91 wetland acres.
Nonpoint Source Characteristics
This watershed is ranked High for runoff impacts on streams, Not Ranked 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.
