Features
Caldron Falls Flowage was created in 1923 when the Wisconsin Public Service Corporation (WPS) constructed the Caldron Falls Dam across the Peshtigo River. Most of the shoreline remains in a wilderness state and is owned by WPS and the state of Wisconsin. Peshtigo River State Forest and Governor Thompson State Park make up the shoreline owned by the state of Wisconsin.
The abundance of forage provides good angling opportunities for a variety of species. Most fish exhibit healthy body conditions. The lake is noted for its muskie fishery, but also provides exciting action for smallmouth bass, largemouth bass, northern pike, panfish and walleye.
Anglers should be aware that many of the shallow rock bars, stump fields and sandbars are unmarked and can pose navigation hazards.
Forage
Juvenile perch, bluegill and crappie are the primary forage for walleye, largemouth bass and northern pike. An abundant white sucker population is heavily utilized by muskie. Golden shiner and various minnows species provide additional forage.
Seasonal Movements
Walleye move into the Peshtigo River during late winter and early spring. The tailwaters below Caldron Falls Dam attract walleye during early spring.
