Fish and Aquatic Life
This 80-acre drainage lake is no deeper than a foot, fed by Maple Creek and drained by Shivering Sands
Creek. More than 350 acres of wooded swampland border the lake and extend to the Lake Michigan
shore. Waterfowl frequent the area--a fall hunting "hot spot."

A shallow drainage lake in a swamp pocket occupying an area submerged by glacial Lake Nippissing. About 384 acres of primarily wooded swampland border the lake and extend to the Lake Michigan shore. The lake is drained by Shivering Sands Creek and is fed by Maple Creek. Winterkill occurs annually. Chief values are waterfowl production and scenic beauty. Public access is not available. The lake bottom is marl with much vegetable material. Numerous duck blinds attest the value of this area for fall hunting.
Author Surface Water Inventory Of Wisconsin
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.
The developed concept plan will identify and evaluate passive treatment technologies that can be implemented to reduce nutrient loads from the wastewater treatment lagoons. The plan will include planning level cost estimates and a summary of the operation and maintenance of the passive polishing cell system.
County Land and Water Management Plan
Door County Soil & Water Conservation Department proposes to conduct a phased approach to the development of protection strategies for its waters including lakes. This phase of the project will collect and analyze information regarding surface water resources in order to develop specific implementation recommendations for phase II indlucing upgrading regulatory programs. Project deliverables shall include a draft and final report containing: 1) an inventory and classification of county inland lakes; 2) appropriate supporting data and maps and; 3) recommendations specifying phase II implementation activities including proposed regulatory standards for shoreland and lake protection.
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.

Dunes Lake is located in the Upper Door County watershed which is 287.02 mi². Land use in the watershed is primarily forest (38%), grassland (22%) and a mix of agricultural (18.90%) and other uses (21.10%). This watershed has 102.85 stream miles, 254,855.32 lake acres and 24,541.39 wetland acres.
Nonpoint Source Characteristics
This watershed is ranked High 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.
