Fish and Aquatic Life
Upper Phantom Lake is a small irregular lake in outwash deposits augmented in acreage by a dam with about an 8-foot head on the outlet to Lower Phantom Lake. A church camp and a YMCA camp occupy parts of the shore line. The fishery consists of pan fish, northern pike and largemouth bass. In 1961, algae, weed, and snail control was necessitated on the beaches. Access is available for boat launching, however, parking is prohibited. There are no adjoining wetlands of consequence.

Phantom Lake (WBIC 766000) was placed on the impaired waters list for total phosphorus in 2016. This lake was assessed during the 2018 listing cycle; new chlorophyll-a sample data were clearly below the 2018 WisCALM listing thresholds for the Recreation use and the Fish and Aquatic Life use. Total phosphorus sample data nearly exceeded the listing thresholds. Based on the most updated information, no change in existing impaired waters listing was needed.

This water was assessed during the 2016 listing cycle; total phosphorus sample data exceed 2016 WisCALM listing thresholds for the Recreation use, however, chlorophyll data do not exceed REC thresholds. Total phosphorus and chlorophyll data do not exceed Fish and Aquatic Life thresholds.

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.

Phantom Lake is located in the Mukwonago River watershed which is 86.21 mi². Land use in the watershed is primarily forest (28.40%), agricultural (22.80%) and a mix of suburban (16.90%) and other uses (31.90%). This watershed has 63.38 stream miles, 2,340.41 lake acres and 4,822.44 wetland acres.
Nonpoint Source Characteristics
This watershed is ranked Medium for runoff impacts on streams, High for runoff impacts on lakes and High for runoff impacts on groundwater and therefore has an overall rank of High. This value can be used in ranking the watershed or individual waterbodies for grant funding under state and county programs.This water is ranked High Lake for individual Lakes based on runoff problems and the likelihood of success from project implementation.
