river, c.310 mi (500 km) long, formed by the confluence of the North Platte (680 mi/1,090 km long) and South Platte (430 m/690 km) rivers at North Platte, Neb. It flows generally E across S Nebraska to join the Missouri River at Plattsmouth, Neb. The river is too flood-prone in spring and too shallow and braided the rest of the year for navigation.

Large congregrations of sandhill cranes rest along the river in central S Nebraska during their migration. The Platte valley was an important route to the West in the 19th cent.; the Mormon Trail followed the north bank, and the Oregon Trail followed the south bank.
