This article is about the John Day River in eastern Oregon. There is also the John Day River in northwestern Oregon.

The John Day River is a tributary of the Columbia River, approximately 284 miles (457 km) long, in northeastern Oregon in the United States. Undammed along its entire length, the river is the third longest free-flowing river in the contiguous United States. There is extensive use of its waters for irrigation. Its course furnishes habitat for diverse species, including wild steelhead and Chinook salmon runs.[4][7] However, the steelhead populations are under federal Endangered Species Act (ESA) protections, and the Chinook salmon have been proposed for such protection.

The river was named for John Day, a member of the Astor Expedition, an overland expedition to the mouth of the Columbia River that left from St. Louis, Missouri, in 1810. Day wandered lost through this part of Oregon in the winter of 1811–1812.[1]

The absence of dams on the river causes its flow to greatly fluctuate throughout the year depending on snowpack and rainfall within the watershed.[8] The highest flow recorded at a gauge on the lower John Day was 43,300 cubic feet per second (1,230 m3/s) on January 2, 1997. The lowest flow was no flow at all, which occurred on September 2, 1966; from August 15 to September 16, 1973; and on nine days in August 1977. The average flow at the gauge is 2,075 cubic feet per second (58.8 m3/s).[6]

Drainage basin

Through its tributaries, the river drains much of the western side of the paleontological sites along its banks.[5][9] Elevations within the watershed range from 268 feet (82 m) at the river's mouth to more than 9,000 feet (2,700 m) in the Strawberry Mountains.[2][10]

The main branch of the John Day River rises in the Strawberry Mountains in eastern John Day Fossil Beds National Monument.

At Kimberly in northwestern Grant County, it is joined from the east by the North Fork John Day River (which had already joined with the Middle Fork John Day River above Monument, Grant County, Oregon). The river then flows west across Wheeler County. At the county line with Jefferson County it flows north, past the Clarno Unit of the John Day Fossil Beds National Monument. As it approaches the Columbia River in north-central Oregon it flows in an increasingly meandering course, forming the boundary between Sherman County to the west and Gilliam County to the east.

The John Day River joins the Columbia from the southeast approximately 16 miles (26 km) northeast of Biggs. The mouth of the river is on the narrow Lake Umatilla reservoir, formed on the Columbia by the John Day Dam, approximately 2 miles (3.2 km) downstream from the mouth of the John Day.

Recreation and ecosystem

The John Day is navigable by rafts and other small river craft by boaters who obtain permits provided by the BLM.[10] Its lower course is used for irrigation of cropland and ranching.[4] In 1988, the United States Congress designated 147.5 miles (237.4 km) of the river from Service Creek to Tumwater Falls as Wild and Scenic for its recreational opportunities. The segment of the river is a popular destination for anadromous steelhead and warm water bass fishing, as well as whitewater rafting.[13]

In addition to wild spring chinook salmon and bass, the river furnishes habitat for Columbia River redband trout, bull trout, and westslope cutthroat trout.[7][14] There are no hatchery salmon or steelhead released in the John Day River.
