About the umatilla river
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.
