Fish and Aquatic Life
Halfmoon Lake, in the Woodboro Watershed, is a 102.49 acre lake that falls in Lincoln County. This lake is managed for fishing and swimming and is currently not considered impaired.

A very soft water seepage lake having slightly alkaline, clear water of high transparency. The shoreline is 60 percent upland consisting of mixed conifers and hardwoods and 40 percent wetland of the coniferous bog type. The littoral zone is 50 percent sand, 40 percent muck, and 10 percent gravel. Fifty percent of the lake is less than 3 feet deep. Moderate densities of submergent and emergent vegetation occur in 80 percent of the lake. Fish species include northern pike, perch, largemouth bass, bluegill, black crappie, pumpkinseed, black bullhead, brown bullhead, common shiner, and golden shiner. Conditions suggest possible use by spring and fall migratory waterfowl. There is no public access. There are 40 dwellings, 5 resorts and 1 organizational camp on the lakeshore.
Surface Acres = 106.4, Maximum Depth = 14 feet, Secchi Disc = 12 feet

Halfmoon Lake was evaluated every two years between 2016 and 2020 for phosphorus, algae, and chloride levels and was found to be in good condition. This lake is on the healthy waters list.

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.

Halfmoon Lake is located in the Woodboro watershed which is 61.99 mi². Land use in the watershed is primarily forest (60.60%), wetland (16.10%) and a mix of open (8.50%) and other uses (14.80%). This watershed has 37.71 stream miles, 2,840.53 lake acres and 5,403.17 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.
