Length: 800 kilometres (500 miles). The Wabash, a tributary of the Ohio/Mississippi, is a river in north Central United States. It is the largest north bank tributary of the Ohio. Its source is in Grand Lake, western Ohio. It then flows west to the south of Fort Wayne, then southwestward to the western border of Indiana, before flowing south and forming the boundary between Indiana and Illinois. It finally enters the Ohio west of Evansville. Its main tributaries are the Tippecanoe, Eel and Mississinewa rivers in the northern part of Indiana, and the White and the Patoka in the south. The tributaries of the upper Wabash, west of Fort Wayne, have been dammed and used for water supply reservoirs and are also used as State Recreation Areas. The Wabash is not a navigable river for commercial craft and so has not attracted much settlement. Crossing points of the Wabash were important during the westward migration and a number of State Historic Sites are found along the border between Illinois and Indiana. |
