Fish and Aquatic Life
Mud lake is a 62.3-acre landlocked seepage lake, with a maximum depth of 3 feet. The 1.7 miles of
shoreline has no public access. This lake drains a 1 square mile basin. There are 47 acres of non-woody
wetlands surrounding the lake. Consistent winterkill precludes a sport fishery. WDNR lacks sufficient
data to make further recommendations for Mud Lake. Monitoring would provide basic trophic state
information so that management decisions can be made to enhance lake health.

A small, landlocked, seepage lake in end moraine. This lake has light brown, alkaline water and a muck bottom. Consistent winterkill prevents the establishment of a fishery. There are no shoreline developments or public access. About 47 acres of non- woody wetland surround the lake providing mallards and blue-wing teal with nesting habitat. Hunting is permitted and a moderate number of both diving and puddle ducks are visitors during the spring and fall migrations. This may be considered a wilderness lake.
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.
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.

Mud Lake is located in the South Branch Manitowoc River watershed which is 189.10 mi². Land use in the watershed is primarily agricultural (60.30%), wetland (17.60%) and a mix of grassland (14.10%) and other uses (8.10%). This watershed has 228.03 stream miles, 86.31 lake acres and 21,287.68 wetland acres.
Nonpoint Source Characteristics
This watershed is ranked High 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.
