Rapids
Rapids are sections of a river where the river bed has a relatively steep stream gradient, gradient, causing an increase in water velocity and turbulence. Flow, gradient, constriction, and obstacles are four factors that are needed for a rapid to be created. Physical factors Rapids are hydrology, hydrological features between a ''run'' (a smoothly flowing part of a stream) and a ''waterfall#Types, cascade''. Rapids are characterized by the river becoming shallower with some Rock (geology), rocks exposed above the flow surface. As flowing water splashes over and around the rocks, air bubbles become mixed in with it and portions of the surface acquire a white color, forming what is called "whitewater". Rapids occur where the stream bed, bed material is highly resistant to the erosive power of the stream in comparison with the bed downstream of the rapids. Very young streams flowing across solid rock may be rapids for much of their length. Rapids cause water aeration of the stream ...

Lake Celilo
Lake Celilo is a long reservoir on the Columbia River in the United States, between the U.S. states of Washington and Oregon. It was created in 1957 with the construction of The Dalles Dam near The Dalles, Oregon, and stretches upstream to the John Day Dam. Its filling drowned the former site of Celilo Falls and the neighboring fishing and trade village sites. Celilo Village, a small, unincorporated community of Native Americans, still exists today, though it is no longer the thriving cultural and economic center it once was. by Jean Johnson, ''Indian Country Today'', 2004-08-24 The reservoir lies in parts of Wasco and |
Lake Wallula
Lake Wallula is a reservoir on the Columbia River in the United States, between the U.S. states of Washington and Oregon. It was created in 1954 with the construction of McNary Dam.

McNary Dam
McNary Dam is a 1.4-mile (2.2-km) long concrete gravity run-of-the-river dam which spans the Columbia River. It joins Umatilla County, Oregon with Benton County, Washington, 292 miles (470 km) upriver from the mouth of the Columbia. It is operated by the U.S. Army Corps of Engineers' McNary Lock and Dam office. The dam is located a mile (2 km) east of the town of Umatilla, Oregon, and 8 miles (13 km) north of Hermiston, Oregon. The dam was originally planned to be named Umatilla Dam, but the Flood Control Act of 1945 renamed the dam in honor of Senator Charles L. McNary of Oregon, who had died in February 1944. The dam provides for slackwater navigation, hydroelectric power generation, recreation, wildlife habitat, and incidental irrigation. Bills for the construction of a dam were introduced in the United States Congress as early as 1931. The United States House of Representatives rivers and harbors committee initially approved the project in April 1941; nav ...

John Day River
The John Day River is a tributary of the Columbia River, approximately long, in northeastern Oregon in the United States. It is known as the Mah-Hah River by the Cayuse people. Undammed along its entire length, the river is the fourth 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."John Day Subbasin Plan", p. 31 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 Pacific Fur Company's overland expedition to the mouth of the Columbia River that left Missouri in 1810. Day struggled through eastern Oregon during the winter of 1811–12. While descending the Columbia River in April 1812, he and Ramsay Crooks were robbed and stripped naked by Native Americans at t ...

Wishram Village
Wishram Village, referred to as nixlúidix by its residents, was a summer and winter village on the Columbia River, Washington, United States occupied by Upper Chinook people. It is considered the largest prehistoric Chinook village site. The site is now part of Columbia Hills State Park.

The village was a common trading site for Indians in the surrounding areas, acting as a link between tribes from the Pacific Coast, and the interior Northwest. The site was visited by nearby Yakamas, as well as those from as far away as the Nez Perce, who would come to trade fish, berries, skins, buffalo, amongst many other items. The village was visited during the westward journey by Lewis and Clark, and again on their eastward return journey, though by the time of the second visit, the village was at a site about d ...
