Fish and Aquatic Life
Leota Lake, in the Allen Creek and Middle Sugar River Watershed, is a 35.65 acre lake that falls in Rock County. This lake is managed for fishing and swimming and is currently not considered impaired.

Source: 1970, Surface Water Resources of Rock County Leota Lake, T4N, R10E, Section 22, 27, Surface Acres = 41, S.D.F. = 1.97, Maximum Depth = 15 feet A shallow, hardwater lake created by an 8-foot dam on Allen Creek. Most of the shoreline is within the Evansville City Park where public access is available. Picnic tables and beach facilities are provided. In 1961, the lake was drawn down preliminary to chemical treatment. A high rough fish and stunted panfish population was present and sport fishing had deteriorated. Repairs to the dike and dam, and beach improvements were made at that time. During the summer of 1962 the fish in the lake and watershed were chemically eradicated, and in 1963 northern pike and largemouth bass were restocked. Fish species now present include bluegills, largemouth bass, bullheads, northern pike and crappies. Algae becomes a problem each year but is successfully treated by the city. Approximately 223 acres of wetland adjoins the northwest side of the lake along Allen Creek. Migratory and nesting waterfowl are common and hunting is allowed.

Leota Lake (WBIC 884700) was placed on the impaired waters list for total phosphorus in 2016. The 2018 assessments showed continued impairment by phosphorus; new total phosphorus sample data overwhelmingly 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, and nearly exceeded the FAL use thresholds. Based on the most updated information, no change in the existing impaired waters listing was needed.

Leota Lake (WBIC 884700) was assessed during the 2016 listing cycle; total phosphorus and chlorophyll sample data exceeded 2016 WisCALM listing thresholds for the Recreation use, but did 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.
Monitor Water Quality or Sediment
Take another year of total phosphorus and chlorophyll-a samples for further support of 2016 listing. Recommended by Sue Graham "We may want an additional year of monitoring chl due to data quality issues in 2014."
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.

Leota Lake is located in the Allen Creek and Middle Sugar River watershed which is 154.01 mi². Land use in the watershed is primarily agricultural (61.50%), grassland (17.30%) and a mix of forest (9.30%) and other uses (11.80%). This watershed has 263.25 stream miles, 96.10 lake acres and 5,963.23 wetland acres.
Nonpoint Source Characteristics
This watershed is ranked Medium for runoff impacts on streams, Not Ranked 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.
