About the Wabash River
The Wabash River is the state river of Indiana. It runs 503 miles from its origin near the western Ohio border to its confluence with the Ohio River at the southwest tip of Indiana. The Wabash includes the longest stretch of undammed river east of the Mississippi, flowing freely from a dam near Huntington, Indiana to its confluence with the Ohio. The river's watershed drains two-thirds of Indiana and a sizeable portion of eastern Illinois. Approximately 6,200 square miles of the river's watershed drains through the Lafayette-West Lafayette riverfront.
The Wabash River's watershed is home to nearly 60% of Indiana's population. The larger cities along the river include Lafayette, Terre Haute, Vincennes, Logansport, and Huntington. Its largest tributary, the White River, runs through Indianapolis, Muncie, and Anderson. The economy of the watershed comes mostly from agriculture along with high levels of manufacturing. Land use in the watershed is primarily agricultural with large tracts of forest and wetlands.
The Wabash River is home to 150 species of fish including the Paddlefish, the oldest surviving animal species in North America. Its watershed provides habitat for Osprey, Bald Eagles, River Otters, and over 100 endangered, threatened, or rare plants and animals.
