Fond Du Lac
Fish and Aquatic Life
Deneveu Lake, in the Lake Winnebago - East Watershed, is a 79.94 acre lake that falls in Fond du Lac County. This lake is managed for fishing and swimming and is currently not considered impaired.

This natural lake is the fourth largest and the deepest lake in Fond du Lac County. The lake exhibits low productivity, a characteristic not common to a lake of this size and depth in this section of the state. The shoreline is intensively developed for homesites. Recent information concerning the fish population is lacking since there is no public access to the lake. The last surveys showed largemouth bass to be the primary game fish, with bluegills and perch and as the primary panfish. A minor population of walleyes is present. Trout were privately stocked in 1958, but apparently failed to provide a fishery.

Deneveu Lake (139300) was assessed during the 2016 listing cycle; total phosphorus and chlorophyll sample data were clearly below 2016 WisCALM listing thresholds for the Recreation use and Fish and Aquatic Life use. This water is meeting these designated uses and is not considered impaired.

Deneveu Lake was recently evaluated during the ten-year period of 2009 through 2018 for results that were reported to the USEPA for the 2020 Clean Water Act condition report. The waterbody is considered impaired, or in poor condition for designated uses which include the quality of fish and aquatic life, recreational use, and public health and welfare (fish consumption and related). Pollutants or problems encountered during sampling (impairments) are determined based on water quality standards outlined in Wisconsin 2020 Consolidated Assessment and Listing Methodology (WisCALM). Assessment results show water conditions that are potentially harmful for Aquatic Life and Recreation uses due to values for total phosphorus that fall into the range expected for an aquatic community in poor health, therefore this water is listed as impaired.
Assessment results during the 2020 listing cycle show impairment by total phosphorus. Chlorophyll levels were also assessed and found to be appropriate for Aquatic Life use and may be appropriate for Recreation use based on 2020 WisCALM standards. Based on the most updated information, this lake was proposed for the impaired waters list in 2020.

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.

DeNeveu Lake is located in the Lake Winnebago - East watershed which is 99.40 mi². Land use in the watershed is primarily agricultural (51.20%), grassland (19.40%) and a mix of suburban (11.60%) and other uses (17.80%). This watershed has 177.39 stream miles, 252.07 lake acres and 1,539.57 wetland acres.
Nonpoint Source Characteristics
This watershed is ranked High for runoff impacts on streams, Not Available 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.
