The Umatilla River is a tributary of the Columbia River, located in northeastern Oregon. The river was historically home to the Umatilla Native American tribe, who fished and hunted along the river. The river runs for 89 miles, beginning in the Blue Mountains and flowing through the Umatilla National Forest. The river's hydrology has been impacted by the construction of several dams, including the McKay and Wildhorse Reservoirs. These dams provide irrigation water for agriculture and hydroelectric power. The river is also used for recreational activities such as fishing, boating, and camping. The Umatilla River supports populations of Chinook salmon, steelhead, and other fish species. Agricultural uses include the growing of wheat, hay, and fruit trees.

Historical River Levels

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 the North Fork Umatilla River and the South Fork Umatilla River, then 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.
