Otter Lake is a drainage lake of moderate fertility with clear water of low transparency. The bottom materials consist mostly of sand and muck, with some gravel and rock. Both the inlet and the outlet streams are considered freely navigable as this lake is part of the Eagle Chain. The principal fish species present are muskellunge, northern pike, largemouth bass and pan fish. The abundant crayfish population is considered a problem. There is access to the lake by means of a city park area, which is located on the channel between Otter and Eagle Lake, so perhaps the best description of the access situation would be that of navigable water. Three resorts are located on the shore line with boat rental facilities at each. There are 62 cottages located on or about the shore.

Insufficient TP data to make assessment. Further monitoring recommended.
Lake Management Plan Implementation
The Town of Washington is sponsoring a project on Anvil Lake, Vilas County. The project will focus on studying water quality and developing an Anvil Lake Management Plan (LMP). Project activities include: 1) Develop water and P budget; 2) Water quality evaluation and groundwater assessment; 3) WiLMS simulation modeling; 4) Stakeholder participation; 5) Collect sediment cores for historical and future lake water quality assessment; 6) Implementation of County sewage ordinance and association shoreline restoration project; 7) Develop annual reports, a scientific investigations report and LMP.
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.

Otter Lake is located in the Eagle River watershed which is 181.70 mi². Land use in the watershed is primarily forest (55.60%), wetland (28%) and a mix of open (12.90%) and other uses (3.50%). This watershed has 146.13 stream miles, 15,720.03 lake acres and 32,094.84 wetland acres.
Nonpoint Source Characteristics
This watershed is ranked Not Ranked for runoff impacts on streams, High 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.
