Fish and Aquatic Life
Jambo Creek is the largest tributary to the East Twin River. It is a nine-mile long stream with fair to poor water quality (WDNR, 1982). The first three miles upstream from its mouth are Class II brown trout waters. Fisheries managers feel this reach is not meeting its potential due to pollution from agricultural runoff.

Jambo Creek (miles 0-3.91) was assessed during the 2018 listing cycle; new biological (fish Index of Biotic Integrity (IBI) scores) 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.

Jambo Creek is a nine mile long, low gradient stream that flows southward through agricultural and forested land before joining with the East Twin River. The first three miles of Jambo Creek above it’s confluence with the East Twin River are considered to be Class II brown trout waters (WDNR 1995). However, biologists believe that because of agricultural runoff this section of river is not meeting its full potential use. The upper 6 miles are considered to be a limited forage fishery or limited aquatic life stream because of low flows and warm summer temperatures. Habitat evaluations from areas of the stream classified as trout waters in 1994, ranged from fair to excellent, with invertebrate HBI scores indicating excellent water quality (Gansberg 1995). Habitat scores in upper sections of the river (non-trout waters) were fair.

The 2018 assessments of Jambo Creek showed impairment by phosphorus; new total phosphorus sample data exceeded the 2018 WisCALM listing criteria for the Fish and Aquatic Life use. Available biological data did not indicate impairment (i.e. no macroinvertebrate or fish Index of Biotic Integrity (IBI) scored in the "poor" condition category). Based on the most updated information, this water was proposed for the impaired waters list.

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 2018. See also the 'monitoring and projects' tab.

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.

Jambo Creek is located in the East Twin River watershed which is 183.58 mi². Land use in the watershed is primarily agricultural (57.30%), grassland (16.50%) and a mix of wetland (14.70%) and other uses (11.50%). This watershed has 314.70 stream miles, 12,446.75 lake acres and 14,181.41 wetland acres.
Nonpoint Source Characteristics
This watershed is ranked High for runoff impacts on streams, High 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.
