Fish and Aquatic Life
Caldron Falls Reservoir (Imp), in the Middle Peshtigo and Thunder Rivers and Upper Peshtigo River Watersheds, is a 1,062.75 acre impoundment that falls in Marinette and Oconto Counties. This impoundment is an outstanding/exceptional resource water under NR102 under the Fisheries Program. This impoundment is managed for fishing and swimming and is currently considered impaired.

A hard water drainage lake (impoundment), on the Peshtigo River, having slightly alkaline, clear water of high transparency. The littoral zone is 60 percent sand, 15 percent gravel, 15 percent muck and 10 percent rubble. The shoreline is primarily upland consisting of mixed hardwoods and conifers with limited areas of coniferous bog wetland. The fish population consists of muskellunge, northern pike, walleye, largemouth bass, smallmouth bass and panfish. During their spring and fall migrations, waterfowl make moderate use of this flowage. There is no public shoreline. The flowage offers a unique recreational area, as the entire shoreline belongs to the Wisconsin Public Service Corporation and is undeveloped. Navigable water access is available, and five boat landings with parking are maintained for public use by the power company.

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.

Caldron Falls Reservoir* is located in the Upper Peshtigo River watershed which is 338.33 mi². Land use in the watershed is primarily forest (62.80%), wetland (31.20%) and a mix of grassland (3.60%) and other uses (2.40%). This watershed has 342.45 stream miles, 1,184.80 lake acres and 48,481.09 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.
