Historical Description
Source: 1969, Surface Water Resources of Sawyer County Upper Holly Lake, T39N, R9W, Section 22
An acid bog lake with an outlet channel to the nearby Sand Lake rearing pond bypass ditch. The lake level is affected by the state operated dam on the bypass ditch. Fish common to the lake are muskellunge, largemouth bass, perch, black crappie, pumpkinseed, and bullheads. Other species present include northern pike, bluegill, rock bass, and white suckers. Thirty acres of spruce swamp and leatherleaf bog border all but parts of the east and west shore of the lake. Waterfowl nesting includes both ducks and loon. The only private development is a nearby farm dwelling. There is no public access or public frontage.

Impaired Waters
This water was assessed during the 2016 listing cycle; new fish tissue data indicates that this waterbody should be on the impaired waters list because of specific consumption advice for mercury.

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
Upper Holly Lake is located in the Couderay River watershed which is 212.25 mi². Land use in the watershed is primarily forest (64.90%), wetland (13.50%) and a mix of open (12.90%) and other uses (8.70%). This watershed has 211.96 stream miles, 18,300.76 lake acres and 14,697.69 wetland acres.
Nonpoint Source Characteristics
This watershed is ranked Low 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.
