Kathan Lake, T39N, R9E, Section 13
A soft water drainage lake having slightly acid, clear water of low transparency. The transparency at the time of survey was affected by the turbidity of the water. Sand is the principal littoral material (55 percent) with muck (35 percent) and some gravel present. The shoreline is mostly upland (55 percent) with a significant portion wetland of the shrub and coniferous type. Floating and submergent vegetation is moderate in density. Fish species inhabiting this lake are muskellunge, northern pike, walleye, largemouth bass, perch, bluegill, crappie, rock bass, pumpkinseed and sucker. There is no public access. Five resorts and eight dwellings are located on the shore.
Surface Acres = 189, S.D.F. = 1.87, Maximum Depth = 15 feet

Kathan Lake (1598300) was assessed during the 2016 listing cycle; total phosphorus sample data were clearly below 2016 WisCALM listing thresholds for Recreation use and Fish and Aquatic Life use. Chlorophyll sample data were clearly below FAL use listing thresholds and did not exceed REC listing thresholds. This water is meeting these designated uses and is not considered impaired.

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.

Kathan Lake is located in the Sugar Camp Creek watershed which is 187.99 mi². Land use in the watershed is primarily forest (58.50%), wetland (24.70%) and a mix of open (13.40%) and other uses (3.50%). This watershed has 123.61 stream miles, 11,669.73 lake acres and 30,139.17 wetland acres.
Nonpoint Source Characteristics
This watershed is ranked Not Ranked for runoff impacts on streams, Medium 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.
