Fish and Aquatic Life
The headwaters of Trimbelle River originate near Martell in Pierce County and flow for 25 miles before discharging into the Mississppi at the Trenton Slough. From a mile and a half above the mouth of the river to its headwaters Trimbelle River is considered an Exceptional Resource Water (ERW) and a Class II Trout water, as well.

The entirety of the Trimbelle River is classified as an Exceptional Resource Water and a Class II Trout water. This water was assessed during the 2018 listing cycle. The portion from the mouth to Little Trimbelle Creek was assessed during the 2018 listing cycle; new total phosphorus and biological (macroinvertebrate Index of Biotic Integrity (IBI) scores) sample data were clearly below 2018 WisCALM listing thresholds for the Fish and Aquatic Life use. The portions from Little Trimbelle Creek to to CTH W 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'.
The nonpoint source priority watershed selection committee should consider the Trimbelle River and Isabelle
Creek Watershed a high priority for selection as a priority watershed project under the Wisconsin Nonpoint Source
Water Pollution Abatement Program.
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 or implementation of a Total Maximum Daily Load analysis, a Nine Key Element Plan, or other restoration work, education and outreach and more. If specific recommendations exist for this water, they will be displayed below online.
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.

Trimbelle River is located in the Trimbelle River and Isabelle Creek watershed which is 221.40 mi². Land use in the watershed is primarily agricultural (40.70%), forest (26.30%) and a mix of grassland (22.90%) and other uses (10.10%). This watershed has 467.20 stream miles, 1,912.55 lake acres and 3,854.20 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.
