Overview

Big Bass Lake is a medium hard water seepage lake having slightly alkaline, light brown water of low transparency. The immediate shoreline is predominantly upland (80 percent), of hardwood and conifer, with the remainder being wetland (20 percent), of bog, meadow, shrub, conifer, and marsh. The littoral materials are composed of silt (65 percent), sand (38 percent), and gravel (7 percent). The growth of floating, emergent, and submergent aquatic vegetation is sparse. Fish species present include northern pike, largemouth bass, yellow perch, bluegill, pumpkinseed, black bullhead, brown bullhead and white sucker. An unimproved public boat landing is located on the east shore. Thirteen dwellings are located on the shoreline. An intermittent outlet flows to the Plover River.

Impaired Waters

Big Bass Lake (1405200) was placed on the impaired waters list for Mercury in fish tissue in 2002. This water was assessed during the 2016 listing cycle; total phosphorus and chlorophyll sample data were clearly below 2016 WisCALM listing thresholds for the Recreation use and Fish and Aquatic Life use. This water was also assessed for chlorides and sample data were clearly below 2016 WisCALM chronic and acute listing criteria for the Fish and Aquatic Life use. This lake is considered impaired for Fish Consumption use and meeting REC and FAL uses.

Condition

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.

Management Goals

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

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.

Watershed Characteristics

Big Bass Lake is located in the Plover and Little Plover Rivers watershed which is 202.19 mi². Land use in the watershed is primarily forest (41.70%), agricultural (23.60%) and a mix of wetland (18%) and other uses (16.60%). This watershed has stream miles, lake acres and 22,761.70 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.
