The Umatilla River is an 89-mile (143 km) tributary of the Columbia River in the U.S. state of Oregon. Draining a basin of 2,450 square miles (6,300 km2), it enters the Columbia near the city of Umatilla in the northeastern part of the state. In downstream order, beginning at the headwaters, major tributaries of the Umatilla River are: North and South Forks of the Umatilla River, Meacham, McKay, Birch, and Butter creeks.
The name Umatilla is derived from the Native American name for the river, which was first recorded as Youmalolam in the journals of the Lewis and Clark Expedition and spelled in many other ways in early books about Oregon.
Famous quotes containing the word river:
“A reaction: a boat which is going against the current but which does not prevent the river from flowing on.”
—Victor Hugo (1802–1885)
