Fish and Aquatic Life
Lyndon Creek is an 8-mile tributary to the Wisconsin River. The lower 6 miles of the creek
are considered a marginal Class III trout stream. Walleye, northern pike, smallmouth bass
and some panfish find their way into the lower reached of the creek from the Wisconsin
River. Land cover in the area is agriculture and wetlands. Cropland and streambank erosion,
barnyard runoff and stormwater runoff from Lyndon Station impact Lyndon Creek. These
sources of pollution impact the habitat in the creek. Surveys conducted in 1995 found the
creek to have fair water quality. In-stream habitat is the major limiting factor to the fishery.
Dissolved oxygen monitoring in 2001 have shown no impact from the wastewater treatment

The Lyndon Creek (Mouth to tributary above Parchem Rd.) was assessed during the 2018 listing cycle; total phosphorus sample data clearly exceeded the 2018 WisCALM listing thresholds 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). This water was not meeting this designated use and was considered impaired. No listing change was needed to this already impaired water.

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.

Lyndon Creek is located in the Dell Creek watershed which is 133.73 mi². Land use in the watershed is primarily forest (43%), agricultural (36%) and a mix of suburban (9%) and other uses (12%). This watershed has 231.97 stream miles, 193.10 lake acres and 4,715.88 wetland acres.
Nonpoint Source Characteristics
This watershed is ranked High for runoff impacts on streams, Medium 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.
