Fish and Aquatic Life
Smith Hollow Creek is a Class I trout stream tributary to Willow Creek. It is also classified as an exceptional resource water (ERW). Water quality is considered to be very good and the stream supports some natural reproduction of brook and brown trout. Nearly three fourths of the watershed has been cleared for agriculture and intensive grazing causes streambank erosion. In the early 1990Ã½s, fisheries management noted a decline in trout population in the stream, with nonpoint source water pollution being the suspected cause.

Smith Hollow Creek is a Class I trout stream (WDNR, 1980) tributary to Willow Creek.
It is also classified ERW. Water quality is considered to be very good (Eagan, 1985').
Intensive grazing causes streambank erosion (Eagan, 1985, WDNR, 19912.7). Fisheries
Management has noted a decline in trout population in the stream, with nonpoint source
water pollution being the suspected cause (WDNR, 1991).
Author Surface Water Inventory Of Wisconsin
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 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.

Smith Hollow Creek is located in the Willow Creek watershed which is 153.08 mi². Land use in the watershed is primarily agricultural (46%), forest (44%) and a mix of suburban (5%) and other uses (4%). This watershed has 339.41 stream miles, 64.58 lake acres and 3,605.43 wetland acres.
Nonpoint Source Characteristics
This watershed is ranked High 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.
