Fish and Aquatic Life
Lea Flowage (Lea Lake), in the Thornapple River Watershed, is a 221.53 acre lake that falls in Rusk County. This lake is managed for fishing and swimming and is currently not considered impaired.

A soft water drainage impoundment on the Little Thornapple River. There is an eight-foot head concrete drop log dam at the outlet. The normal outlet flow is approximately 1.0 cfs. Northern pike, bluegills, pumpkinseed, black crappie, white suckers, and black bullheads are all present. The lake is subject to occasional partial winterkill. Upland there are areas of brush swamp at the outlet and there are areas of brush swamp at the outlet and on the east shore. There is also a marsh by the inlet. Sand, gravel, and boulders are the hard bottom types present, but the littoral zone is about 50 percent muck. Game value includes some nesting ducks and the presence of muskrats. There is no private development as the entire lake is in Rusk County Forest land. There is a public access near the dam on the southeast corner of the lake and on the west shore near the outlet.

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.

Lea Flowage (Lea Lake) is located in the Thornapple River watershed which is 229.97 mi². Land use in the watershed is primarily forest (58.10%), wetland (36.50%) and a mix of grassland (2.80%) and other uses (2.60%). This watershed has 244.30 stream miles, 193.31 lake acres and 38,871.25 wetland acres.
Nonpoint Source Characteristics
This watershed is ranked Low for runoff impacts on streams, Low 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.
