Fish and Aquatic Life
Twin Hill Creek is a 6-mile long tributary to the Neshota River, located southeast of Green Bay. It flows through high intensity agricultural land, and very little information is known about the current condition of this stream. It currently has the default classification of a warm water sport fishery (WDNR 2001). Surveys in 2002 found a fish community dominated by dace, creek chub and white sucker. Stream flow was very low on the date of the survey, and the IBI ranking was fair. In West Twin River tributaries, cobble and gravel dominated the bottom substrate except at Twin Hill Creek where clay was common. Twin Hill Creeks shows a need for improved buffers due to bank erosion depositing silt or clay in the stream channel and degraded habitat.

Twin Hill Creek was evaluated for bug community health every two years between 2016 and 2020; bug community was found to be in fair health. In 2020 this creek was evaluated for phosphorus and levels were too high for sustained healthy aquatic communities. A phosphorus listing was added in 2020.

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.

Twin Hill Creek is located in the West Twin River watershed which is 180.11 mi². Land use in the watershed is primarily agricultural (54.30%), grassland (21.50%) and a mix of wetland (10.60%) and other uses (13.80%). This watershed has 360.91 stream miles, 1,898.59 lake acres and 10,189.53 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.
