Historical Description
Source: 1969, Surface Water Resources of Sawyer County Mason Lake, T38, 39N, R3W, Section 35,36 Surface Acres = 190.0, Maximum Depth = 39 feet, M.P.A. = 65 ppm, Secchi Disk = 9 feet.
A hard water drainage lake, it has an outlet flow of an estimated 2.4 cfs. flowing into Mason Creek. There are inlet streams from Evergreen Lake and Swamp Lake, both warm water fish habitats. The fish population of Mason Lake consists of muskellunge, walleyes, largemouth bass, and panfish. Extensive spruce swamps and bogs are located on the northeast shore and at the inlet streams. Ducks and loon commonly nest here, and muskrats are common. An access is located at the town road crossing the outlet. It has no other public frontage. Private development consists of one resort and boat rental place and eight cottages and homes.

Condition
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.

Management Goals
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
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.

Watershed Characteristics
Mason Lake is located in the Lower North Fork Flambeau River watershed which is 153.97 miĀ². Land use in the watershed is primarily forest (71%), wetland (25.20%) and a mix of open (2.90%) and other uses (0.90%). This watershed has 171.97 stream miles, 2,087.44 lake acres and 20,811.87 wetland acres.
Nonpoint Source Characteristics
This watershed is ranked Not Ranked 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.
