The Peshtigo River is a 136-mile waterway originating in Forest County and flowing southeasterly through Marinette County before emptying into Green Bay. Known for its diverse aquatic environments ranging from swift rapids to calm pools, the river features several flowages created by dams along its course. The Peshtigo offers excellent fishing opportunities throughout the year, with different sections of the river providing habitat for various fish species. The river is also historically significant as it provided refuge for survivors of the devastating Peshtigo Fire of 1871, which claimed at least 1,200 lives and remains the deadliest fire in U.S. history.
