Fish and Aquatic Life
Ditch 3 is an eight-mile tributary to Fourmile Creek and is classified as a class I and II trout stream. The classification of the lower reaches was unknown, however, surveys completed in 1997 suggest the stream supports a Class II trout fishery. Brook trout are found throughout the ditch with the highest densities in the upper reaches. In-stream habitat is limited by sedimentation primarily from wind erosion, lack of fish cover, ditching and elevated water temperatures at downstream reaches. The ditch was likely over-dredged in the past creating wide and deep channels with sluggish current velocity. Nitrate concentrations have been as high as 6 ppm.

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.

Ditch # 3 is located in the Fourmile and Fivemile Creek watershed which is 213.96 mi². Land use in the watershed is primarily agricultural (41.80%), forest (33.10%) and a mix of grassland (12.20%) and other uses (12.80%). This watershed has stream miles, lake acres and 13,528.97 wetland acres.
Nonpoint Source Characteristics
This watershed is ranked Medium 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.
