Historical Description
Source: 1977, Surface Water Resources of Oconto County Maiden Lake, T32N, R16E, Section 7
A hard water drainage lake having slightly alkaline, clear water of very high transparency. The shoreline is primarily upland, consisting of mixed hardwoods and conifers, with small areas of swamp conifer wetland. The littoral zone is composed of gravel (30 percent), sand (20 percent), rubble (20 percent), marl (15 percent), muck (10 percent), and boulders (5 percent). Waterfowl make limited use of this lake on their spring and fall migrations. The fish population consists of walleye, largemouth bass, smallmouth bass, bluegill, pumpkinseed, green sunfish, perch and white sucker. The Town of Riverview provides public access without parking. One hundred eleven dwellings and two resorts are located on the shoreline.

Impaired Waters
Maiden Lake (487500) was placed on the impaired waters list for Mercury in fish tissue in 1998. This water 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 lake is considered impaired for Fish Consumption use and meeting REC and FAL uses.

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
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
Maiden Lake is located in the South Branch Oconto River watershed which is 219.27 mi². Land use in the watershed is primarily forest (75.10%), wetland (14.70%) and a mix of agricultural (6.10%) and other uses (4.00%). This watershed has 216.92 stream miles, 2,812.48 lake acres and 20,277.98 wetland acres.
Nonpoint Source Characteristics
This watershed is ranked Low for runoff impacts on streams, Not Ranked for runoff impacts on lakes and Low for runoff impacts on groundwater and therefore has an overall rank of Low. 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.
