The Omo is an important river of southern Ethiopia.
This river rises in the Shoan highlands and is a perennial river with many affluents. In its course of some 370 miles (600 km) it has a total fall of about 6000 ft (2,000 m) (from 7600 ft at its source to 1600 ft at lake-level), and is consequently a very rapid stream, being broken by the Kokobi and other falls, and navigable only for a short distance above where it empties into Lake Turkana, one of the lakes of the Great Rift Valley.
Its most important tributary is the Gibe River ; smaller tributaries include the Wabi and Gojeb Rivers.
