Fish and Aquatic Life
Pywaosit Lake, in the Lower Oconto River Watershed, is a 122.21 acre lake that falls in Menominee County. This lake is managed for fishing and swimming and is currently not considered impaired.

A medium hard water drainage lake having alkaline water of high transparency. Littoral materials consist chiefly of sand and some muck. Adjoining shore line is primarily an oak-pine upland. Wetland areas are located in the vicinity of the inlet and outlet streams and a limited area on.the southwest shore. Fishery resource is northern pike, largemouth bass and pan fish. Preservation of marsh weeds, particularly those bordering the inlet and outlet streams, is essential to the preservation of northern pike. Good development of the common aquatic plants both emergent and submergent. Considerable area lies in the 40-50 foot depth zone. Both the inlet and outlet streams can be traversed by small watercraft and afford access to lakes in the Pestigo-Moshawquit chain. Three dwellings are located on the shore line. Tertiary company roads adjoin the lake at several locations. Moderate utilization by waterfowl during the fall migration.

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.

Pywaosit Lake is located in the Lower Oconto River watershed which is 196.48 mi². Land use in the watershed is primarily forest (33.70%), agricultural (25.80%) and a mix of wetland (23.90%) and other uses (16.60%). This watershed has 314.34 stream miles, 3,972.16 lake acres and 24,684.40 wetland acres.
Nonpoint Source Characteristics
This watershed is ranked Low for runoff impacts on streams, Not Ranked 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.
