Fish and Aquatic Life
Moose Lake, in the West Fork Chippewa River Watershed, is a 1,558.98 acre lake that falls in Sawyer County. This lake is managed for fishing and swimming and is currently considered impaired.

A soft water, drainage impoundment on the West Fork of the Chippewa River. The Big and Little Moose Rivers also flow into this flowage. The fish population consists of muskellunge, walleye, largemouth bass, smallmouth bass, and panfish. The Moose Lake dam is owned by the Chippewa and Flambeau Improvement Company. Originally constructed in 1875 to facilitate log driving, it has subsequently been used for reservoir purposes to impound water during periods of surplus flow for release during periods of low flow. Its normal estimated flow is 147 cfs. Draw down occurs in October and its maximum allowable decrease is seven feet. Thisshallow flowage has an extensive cover of rooted aquatic and log debris. Both nesting and migratory ducks as well as muskrats are common. Private development consists of 11 resorts and boat rental places, and 80 cottages. Two public accesses provide boat launching at a site near the dam and on the north shore. Of the 27.45 miles of shoreline, 4.44 miles are part of the Chequamegon National Forest. All the named and unnamed feeder streams to Moose Lake have warm water fish habitat.

Moose Lake (WBIC 2420600) was placed on the impaired waters list in 1998 for Mercury and for Total Phosphorus in 2016. The 2018 assessments showed continued impairment by phosphorus; new total phosphorus sample data exceeded the 2018 WisCALM listing thresholds for the Recreation use and Fish and Aquatic Life use. Chlorophyll-a sample data clearly met both of the use thresholds. Based on the most updated information, no change in the 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.
Information and Education
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.

Moose Lake is located in the West Fork Chippewa River watershed which is 284.78 mi². Land use in the watershed is primarily forest (62%), wetland (33.60%) and a mix of open (4.30%) and other uses (0%). This watershed has 256.71 stream miles, 6,208.10 lake acres and 60,035.54 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.
