Fish and Aquatic Life
Spruce Lake, in the Manitowish River Watershed, is a 16.48 acre lake that falls in Vilas County. This lake is managed for fishing and swimming and is currently not considered impaired.

Spruce Lake is an infertile seepage lake, having medium brown, slightly acid water of moderate transparency. The bottom is composed chiefly of muck with a small amount of gravel present. The outlet is of an intermittent nature. The principal fish species present are the northern pike and largemouth bass. This lake has had a stunted pan fish problem. Recently, the lake was chemically treated with rotenone to eradicate the existing fish population which was composed chiefly of stunted perch. The present population of northern pike and largemouth bass wereintroduced to re-establish a sport fishery in this lake and evaluate chemical treatment in a lake of this type. Spruce Lake is one of the lakes under control of the Five Lakes Fishery Research Project and requires the obtaining of a free permit at the Escanaba Lake checking station. Access is difficult even though a graded road passes near the lake. Boat rental facilities are available to the public. This lake also provides aesthetic qualities, as there are no commercial or private developments located on the shore line.

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.

Spruce Lake is located in the Manitowish River watershed which is 268.60 mi². Land use in the watershed is primarily forest (66.90%), wetland (19.10%) and a mix of open (13.30%) and other uses (0.70%). This watershed has 212.08 stream miles, 22,943.16 lake acres and 33,727.48 wetland acres.
Nonpoint Source Characteristics
This watershed is ranked Low 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.
