A medium hard water drainage lake (impoundment) on the Menominee River, having neutral, light brown water of moderate transparency. Littoral materials consist of sand (70 percent), rubble (15 percent), boulders (10 percent) and gravel. The shoreline is entirely upland consisting of mixed conifers and hardwoods. A diversified fish population exists consisting of northern pike, walleye, largemouth bass, smallmouth bass, perch, bluegill, black crappie, rock bass, pumpkinseed, white sucker, burbot and forage species. Waterfowl make moderate use of this impoundment. Public access is restricted to navigable water via the Menominee River, however, an access site and campground is maintained by the Wisconsin-Michigan Power Company for public use. There are also 2 resorts and 5 dwellings on the shoreline.

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.

Twin Falls Flowage is located in the Pine River watershed which is 342.57 mi². Land use in the watershed is primarily forest (69.50%), wetland (24.80%) and a mix of open (3.20%) and other uses (2.60%). This watershed has 348.02 stream miles, 6,893.46 lake acres and 35,145.32 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.
