Fish and Aquatic Life
Harmon Lake, in the Brill and Red Cedar Rivers Watershed, is a 100.16 acre lake that falls in Washburn County. This lake is managed for fishing and swimming and is currently considered impaired.

A soft water, seepage lake, it is landlocked and is subject to infrequent
but complete winter-kills. Its average depth is eight feet and in
years of low water levels the lake is prone to freeze-out. The
last fish kill occurred in 1964-65. The present fishery is made up of
northern pike, largemouth bass, bluegills and a few smallmouth bass. The
lake is irregularly shaped with
a large, shallow bog off the west shore. The littoral bottom is
predominantly boulder, with lesser amounts of muck in the west bay, and
unsorted sand and gravel. The lake has clear water
but a scarcity of vegetation except in the west bay. The entire
lakeshore is upland with mixed hardwoods. There are few furbearers
here in the absence of wetlands. Nesting ducks include mallards,
teal, and wood ducks. A few other diving ducks are present here in
spring and fall migration periods. The entire lakeshore is in public
frontage as part of the Washburn County Forest, hence has no private
development. A county campground was constructed on the lake's
north shore and provides swimming, picnicking, camping and public access.
Author Surface Water Inventory Of Wisconsin
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.

Harmon Lake is located in the Brill and Red Cedar Rivers watershed which is 297.68 mi². Land use in the watershed is primarily forest (49.40%), agricultural (20.30%) and a mix of grassland (10.70%) and other uses (19.60%). This watershed has 264.90 stream miles, 6,282.34 lake acres and 15,832.05 wetland acres.
Nonpoint Source Characteristics
This watershed is ranked Medium for runoff impacts on streams, Medium 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.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.
