Course


The Grande Ronde River rises in the Blue Mountains near the Anthony Lakes recreation area in the Wallowa–Whitman National Forest in southwestern Union County approximately 20 miles (32 km) south of La Grande. It flows generally north along the east side of the Blue Mountains, then east, past La Grande, then generally northeast through the Grande Ronde Valley in a meandering course between the Blue Mountains and the Wallowa Mountains, receiving Catherine Creek east of La Grande.

Approximately 10 miles (16 km) northwest of Minam it receives the Wallowa River from the southeast, then receives the Wenaha River at Troy just south of the Washington border. Approximately 35 miles (56 km) miles upstream from its mouth on the Snake river, it crosses into southeastern Washington. It traverses the extreme southeast corner of the state. It receives Joseph Creek from the south 2 miles (3.2 km) upstream from its mouth on the Snake at Rogersburg Washington. Its mouth on the Snake is approximately 5 miles (8 km) north of the Oregon border, and is 15 miles (24 km) downstream from the mouth of the Salmon River on the Snake River.

The mouth of the Grande Ronde River is at river mile 169 of the Snake River, and is 493 miles (793 km) from the Pacific Ocean.[3]


River modifications


A diversion channel approximately 5 miles (8 km) long in the Grande Ronde Valley east of La Grande allows the river to bypass a long meandering loop, providing access to its water for irrigation.


History

The Grande Ronde River at Elgin, Oregon

In the early 19th century, the valley of the river was inhabited by Nez Perce, Umatilla, Walla Walla, and Cayuse tribes of Native Americans. Numerous archaeological sites are on the public land around the river.

The Grande Ronde River was given its name sometime before 1821 by French Canadian voyageurs working for the Montreal-based fur trading North West Company.[7] Grande Ronde is a French name meaning "great round".[8]

A portion Grande Ronde and its valley were part of the Oregon Trail. It was first used by settlers in 1844 when Moses "Black" Harris led his party to the river from Fort Hall and then turned northwest to cross the Blue Mountains. Harris' navigation would be subsequently repeated, becoming a regular part of the Oregon Trail.[9] The river was called the "Grand Round River" by at least one English-speaking traveler.[10]

In 1988, the United States Congress designated about 44 miles (71 km) of the river, from its confluence with the Wallowa River to the Oregon–Washington border, as the Grande Ronde Wild and Scenic River, as part of the National Wild and Scenic Rivers System.

The river today is a popular destination for hunting, especially for game animals such as mule deer, elk, black bear, cougar, and bighorn sheep. Fishing, rafting and hiking are also popular along the designated Wild and Scenic portion of the river. Most of the middle reaches of the river are inaccessible to motor vehicles.


Fish


The Grande Ronde River supports populations of spring chinook salmon, summer steelhead, bull trout, mountain whitefish, as well as other species. The river has a sport steelhead fishery and has some tribal fishing for spring chinook.
