Miami (mī̇-äm′ĭ), a river in the western part of Ohio, flows south for 150 miles and empties into the Ohio 20 miles west of Cincinnati. Miami Canal runs beside it for 70 miles, and together they furnish extensive water-power for manufactures. It is sometimes called the Great Miami to distinguish it from the Little Miami, which runs for 100 miles in the same direction, and flows into the Ohio, six miles east of Cincinnati.
