Fish and Aquatic Life
Plum Lake, in the St. Germain River Watershed, is a 1,057.46 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 not considered impaired.

Plum Lake is a drainage lake of moderate fertility. It has slightly acid, clear water of high transparency. Bottom materials consist of sand, gravel and muck in about equal proportions with some rock also present. Both the inlet and the outlet streams areconsidered to be navigable. Principal fish species present in the lake are muskellunge, northern pike, walleye, large and smallmouth bass and pan fish. Public access is available by means of a WCD landing and a county highway; however, the county highway is without nearby parking. There is also navigable water access and difficult-or unimproved access available. Other public use facilities consisting of 15 resorts with three boat rental facilities, a WCD public campground and two youth camps. There are 61 cottages located on or about the shore. This lake provides excellent public use facilities.

Plum Lake (1592400) was assessed during the 2016 listing cycle; total phosphorus and chlorophyll sample data were clearly below 2016 WisCALM listing thresholds for the Recreation use and Fish and Aquatic Life use. This water is meeting these designated uses and is not considered impaired.

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.

Plum Lake is located in the St. Germain River watershed which is 70.11 mi². Land use in the watershed is primarily forest (74.60%), open (13.90%) and a mix of wetland (10.70%) and other uses (0.80%). This watershed has 39.57 stream miles, 3,101.31 lake acres and 5,357.65 wetland acres.
Nonpoint Source Characteristics
This watershed is ranked Not Ranked 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.
