a river of the United States of North America, is formed by the confluence of the St Joseph's and St Mary's Rivers at Fort Wayne, in the state of Indiana. It flows in a N.E. direction through that state and Ohio, till it falls into Maumee Bay, at the W. extremity of Lake Erie, after a course of 100 miles. It is navigable through all its extent for boats, and for steamers as far as Defiance, 60 miles up. The Wabash and Erie Canal extends along the banks through the whole course of the river.
