Fish and Aquatic Life
Kruson Slough is a seepage and spring fed oxbow lake in the flood plain of the Wisconsin River 1.5 miles northwest of Lone Rock. Smith Lake adjoins the upper end of Cruson Slough. An earthen dike constructed in 1968 controls the low water level for waterfowl management and enhances the sport fishery. During high vater the Wisconsin River inundates the lake and brings in both rough and game fish. The principal sport fishery includes good populations of largemouth bass, bluegills and northern pike. Crappies, yellow perch, pumpkinseeds, bullheads and probably a few channel catfish are also available. Carp, buffalo and white suckers are abundant but do not appear to create a severe use problem. Brook silversides and other forage species are abundant. Carp were seined commercially until about 1947. Largemouth bass and warmouth bass fingerlings were stocked by the Wisconsin Conservation Department in 1947 and 1948.
The entire lake lies within the Lone Rock Public Hunting and Fishing Area, which is popular with waterfowl and deer hunters, and fishermen. A total of 182 acres of deep marsh and shrub swamp wetland adjoins the south shore. Scrub oak grow on the high sand banks adjoining the north and southwest shores. Game assets include muskrats, mink, beaver, otter, migratory and nesting waterfowl, deer, and ruffed grouse. Access is provided by a trail following the northshore, and a gravel launching ramp for small boats is located at the dike.

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.

Cruson Slough is located in the Bear Creek watershed which is 136.54 mi². Land use in the watershed is primarily forest (46.40%), agricultural (24.60%) and a mix of grassland (15.20%) and other uses (13.80%). This watershed has 236.07 stream miles, 119.46 lake acres and 6,798.61 wetland acres.
Nonpoint Source Characteristics
This watershed is ranked Medium for runoff impacts on streams, Not Ranked 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.
