Fish and Aquatic Life
Jennings Creek is a tributary to Duck Creek. The stream supports a Class II trout fishery. Although the creek is fairly well protected by wetlands, there are still in-stream habitat and water quality issues. Straightening of the stream has resulted in poor in-stream habitat in some locations. In addition, a campground diverts a portion of the stream flow to form a lake. The lake acts to warm the water and once the water is discharged back to the stream, it has an increased temperature and can cause water quality and habitat problems.

Jennings Creek T12N, R11E, Section 20,Surface Acres = 13.24, Miles = 9.1, Gradient = 13.18 feet per mile.
A small spring-fed stream tributary to the Middle Branch, Duck Creek.
The stream has good water quality but has unfortunately been bracketed by private
fish hatchery development. The Conservation Department owns 410 acres with
3.0 miles of stream managed as public hunting and fishing grounds. Brook trout
are common and there is a long history of stocking of this species. Nearly all
lands adjoining state property are posted against trespass at present. Over
212 acres of wetland adjoin the stream. Waterfowl provide fair shooting and
muskrats are present in significant numbers.

Jennings Creek was assessed during the 2018 listing cycle; new biological (macroinvertebrate Index of Biotic Integrity (IBI) scores) 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.

Jennings Creek is located in the Duck Creek and Rocky Run watershed which is 140.89 mi². Land use in the watershed is primarily agricultural (53%), forest (19%) and a mix of wetland (15%) and other uses (10%). This watershed has 232.25 stream miles, 1,895.92 lake acres and 16,023.66 wetland acres.
Nonpoint Source Characteristics
This watershed is ranked Medium for runoff impacts on streams, Low 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.
