如果要问印地安那州最长的河流是什么？ 无疑是wabash river， 具体信息如下（来源于wikipedia）:

The Wabash River /ˈwɔːbæʃ/ is a 503-mile-long (810 km)[1] river in the Midwestern United States that flows southwest from northwest Ohio near Fort Recovery across northern Indiana to southern Illinois, where it forms the Illinois-Indiana border before draining into the Ohio River, of which it is the largest northern tributary. From the dam near Huntington, Indiana to its terminus at the Ohio River, the Wabash flows freely for 411 miles (661 km).  The Wabash is the state river of Indiana, and subject of the state song "On the Banks of the Wabash, Far Away" by Paul Dresser.
