Historical Description
Source: 1971, Surface Water Resources of Calumet County Round Lake, T19N, R20E, Section 1(2), Area = 10.0 acres, Maximum Depth = 55 feet, Secchi Disk = 7 feet.
Round Lake is a landlocked seepage basin containing medium brown hard water. At 55 feet it is the deepest lake in Calumet County. Silt and muck are the predominant littoral bottom material present along with a lesser amount of sand. In 1959 the lake was treated with chemicals to eradicate the very marginal warm water fishery then present. After this highly successful project the lake was restocked with bluegills, largemouth bass, and rainbow trout. Today the lake supports an excellent base-- bluegill-- trout fishery. A thermo-chemical profile of Round Lake is shown in Figure 11. In addition to being excellent fishing waters, Round Lake supports a wide variety of wildlife species. Hooded merganser, blue-winged teal, mallard, and ringneck duck are but a few waterfowl species observed. Sora rails, other shorebirds, and muskrats are also present. Round Lake suffers from very rare partial winterkills (bluegills most affected) and receives pollution in the form of barnyard drainage. At times algae blooms are present. Most of the shoreline is either pasture or under cultivation. Developments consist of one farm and a town road around the north end of the lake. This road provides public access. Two boat launching areas and limited parking areas are available. Round Lake is the most valuable water from a recreational and ecological viewpoint in Calumet County and as such should be subjected to every effort to protect and enhance its natural attributes.

Impaired Waters
Round Lake (WBIC 68600) was listed for total phosphorus in 2016. The 2018 assessments showed continued impairment by phosphorus; new total phosphorus and chlorophyll-a sample data exceeded the 2018 WisCALM listing thresholds for the Recreation use and Fish and Aquatic Life use. Based on the most updated information, no change in the existing impaired waters listing was needed.

Condition
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.

Recommendations
Nutrient Budget Development
Calumet County proposes to quantify and compartmentalize nutrient budgets for the four lakes situated along the Calumet/Manitowoc County boarder which includes Round, Becker, Boot, and Long Lakes through in-lake, tributary, groundwater and watershed monitoring and modeling.
Management Goals
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
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.

Watershed Characteristics
Round Lake is located in the North Branch Manitowoc River watershed which is 76.97 mi². Land use in the watershed is primarily agricultural (61.80%), grassland (16%) and a mix of wetland (14.60%) and other uses (7.50%). This watershed has 129.77 stream miles, 292.80 lake acres and 7,389.45 wetland acres.
Nonpoint Source Characteristics
This watershed is ranked Not Ranked 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.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.
