Fish and Aquatic Life
Twin Lakes, in the Tamarack Pioneer River Watershed, is a 627.71 acre lake that falls in Vilas County. This lake is an outstanding/exceptional resource water under NR102 under the Fisheries Program. This lake is managed for fishing and swimming and is currently considered impaired.

South Twin Lake is a drainage lake of moderate fertility, having clear water of moderate transparency. Bottom materials are composed principally of sand, with rock and gravel also present. The inlet and outlet streams are both considered navigable. principal fish species present are the muskellunge, walleye, largemouth bass, smallmouth bass and pan fish. The lake is also known to contain brook trout and cisco. Public access is possible by the means of a town road with nearby parking facilities and by navigating either the inlet or outlet streams. Public use facilities consist of eight resorts and two boat rental establishments. There are 62 cottages located on the shore line.

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.

This watershed has 183.22 stream miles, 14,006.68 lake acres and 23,826.05 wetland acres.
Nonpoint Source Characteristics
This watershed is ranked Low for runoff impacts on streams, Medium for runoff impacts on lakes and Low for runoff impacts on groundwater and therefore has an overall rank of Low. 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.
