Fish and Aquatic Life
This hard water, drainage lake is one of a group known collectively as the Trempealeau lakes. It receives water from First Lake and water from its outlet flows into Third Lake. The water is alkaline, clear (though often turbid), and it has a low transparency. The lake is within the Mississippi River floodplain and as a result, sometimes contain many of the fish species present in the river. Normally, its basic fishery consists of northern pike, largemouth bass, perch, bluegill, crappie, rock bass, pumpkinseed, and bullhead. Carp have been abundant and they are commercially fished under state contract. Public access is present. Game values include muskrat, beaver, nesting teal, mallard, and wood duck, and migrant coot, puddle ducks, and diving ducks.

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.

Second Lake is located in the Lower Black River watershed which is 189.82 mi². Land use in the watershed is primarily forest (42%), agricultural (20.30%) and a mix of wetland (13.80%) and other uses (23.70%). This watershed has 383.70 stream miles, 1,042.10 lake acres and 17,676.19 wetland acres.
Nonpoint Source Characteristics
This watershed is ranked Not Available for runoff impacts on streams, Not Available 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.
