Fish and Aquatic Life
Deep Lake, in the Brill and Red Cedar Rivers Watershed, is a 43.01 acre lake that falls in Washburn County. This lake is managed for fishing and swimming and is currently not considered impaired.

A soft water, seepage lake, it is landlocked and has a fishery that
includes walleyes, largemouth bass, and bluegills. It is an elongated,
single basin lake with a wooded island near the south end. The shoreline
is all upland with hardwood vegetation and slopes steeply in places. The
littoral bottom is hard materials of sand, gravel and boulder. A few
mallards and teal nest around thelake but furbearer use is insignificant.
A private campground is located on the north end. Private development
consists of three cottages. A public access is located midway along the
west shore and is the extent of the lake's public frontage.

Deep Lake (WBIC 1844000) was placed on the impaired waters list for total phosphorus in 2012. 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 exceeded the REC use thresholds, but clearly met the FAL use thresholds. Based on the most updated information, no change in the existing impaired waters listing was needed.

Deep Lake (1844000) was placed on the impaired waters list for total phosphorus in 2012. The 2016 assessments showed continued impairment by phosphorus; total phosphorus and chlorophyll sample data exceeded 2016 WisCALM listing thresholds for the Recreation use, but did not exceed Fish and Aquatic Life thresholds. Based on the most updated information, no change in existing impaired waters listing is needed.

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.

Deep 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.
