Historical Description
Source: 1963, Surface Water Resources of Vilas County Anderson Lake, T-40-N, R-8-E, Section 12,
A seepage lake, Anderson Lake has medium brown acid water of very low fertility and very low transparency. Bottom materials are mostly muck. Considered a bass-pan fish lake, largemouth bass are rated as abundant and walleyes are known to be present. Public access is available over state land but is difficult. Aesthetic values of the lake are good. Beaver are present on the lake.
Area = 35 Acres, Maximum Depth = 25 feet,

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.

Recommendations
County Land and Water Management Plan
Town of St. Germain proposes an extensive land and water resource protection program that includes the areas in and around Big and Little St. Germain, Lost Lake and other area water resources. This project will be a broad based long term cooperative planning effort involving the St. Germain Planning Committee, town officials, UW-Extension office and concerned citizens.
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
Shannon 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.
