Nebraska has more miles of rivers than any other state in the nation. Four major rivers exist in Nebraska, in addition to smaller ones. The Platte, the Niobrara, the Missouri and the Republican all drain many square miles of land.
The Platte River, which starts at the city of North Platte, is formed from the North Platte River and the South Platte River and eventually empties into the Missouri River. The Platte flows through the center of the state from west to east. The Niobrara River also crosses the state from west to east, but it goes through the northern part of the state and flows into the Missouri River. The Republican River crosses the southern portion of the state.
