Platte River (Missouri) - Tributaries

Tributaries

• Near its headwaters in Iowa the Platte collects minor branches known as the West Platte River, Middle Platte River, and East Platte River.
• In Buchanan County, Missouri, it collects the One Hundred and Two River and the Third Fork, which rises in Gentry County and flows southwardly through DeKalb County, past Union Star. The Third Fork collects the Little Third Fork, which flows southwardly through DeKalb and Buchanan Counties, past Clarksdale.
• In Platte County, Missouri, it collects the Little Platte River, which rises in DeKalb County and flows south-southwestwardly through Clinton and Clay Counties, past Plattsburg and Smithville. Near Smithville, a U.S. Army Corps of Engineers dam causes the Little Platte River to form Smithville Lake.
