Fish and Aquatic Life
Hidden Lake, in the Lower North Branch Oconto River Watershed, is a 34.42 acre lake that falls in Oconto County. This lake is managed for fishing and swimming and is currently not considered impaired.

A medium hard water drainage lake having slightly alkaline, light brown water of moderate transparency. The outlet flows to the North Branch of the Oconto River. The shoreline is 60 percent wetland, of hardwood swamp, and 40 percent upland, consisting primarily of hardwoods. Littoral materials consist of sand (50 percent), muck (45 percent) and gravel (5 percent). Waterfowl make limited use of this lake. Submergent and floating vegetation are moderate in density in most of the littoral zone. The known fish population consists of largemouth bass, perch, bluegill and bullhead. There is no public access. One dwelling is located on the shoreline.

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 Town of Lakewood proposes to conduct a county-wide lake classification and ordinance study. The project will be used as a component in the larger land use planning process to create a set of recommended ordinances, or recommended amendments to existing ordinances for better protection of county lake resources.
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.

Hidden Lake is located in the Lower North Branch Oconto River watershed which is 389.28 mi². Land use in the watershed is primarily forest (68.90%), wetland (22.60%) and a mix of agricultural (2.90%) and other uses (5.70%). This watershed has 410.78 stream miles, 5,377.75 lake acres and 51,397.21 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.
