The Columbia River is the largest river in volume flowing into the Pacific Ocean from North America. Its headwaters are located in the Canadian Rockies of British Columbia, and it flows through the east-central portion of Washington. The last 300 miles (480 km) form the Washington- Oregon state line. It flows into the Pacific Ocean at Astoria, Oregon.
Roll on, Columbia, roll on, roll on, Columbia, roll on
Your power is turning our darkness to dawn
Roll on, Columbia, roll on. -- Woody Guthrie
The Columbia is a source of hydroelectric power, hosting the Bonneville and Grand Coulee dams, among others. These dams, like so many others in the world, came with a price: at one time the river was thick with salmonThis article is about the fish. For the color, see salmon (color). Salmon is the common name for several species of fish of the Salmonidae family. Several other fishes in the family are called trout. Salmon live in both the Atlantic and Pacific Oceans., and the presence of the dams together with overfishing have been major factors in the reduction of populations of this fish. Fish ladderBonneville Dam on the Columbia River Fishways most commonly referred to as fish ladders but also known as fish passes are structures placed on or around man-made barriers (such as dams and weirs) to assist the natural migration of diadromous fishes. Mosts have been installed to help mitigate the harm to this fish, but there is still much discussion of breaching some of the smaller dams along the river in order to help the salmon runs return. Other benefits the dams provide, besides hydroelectric power, include navigation and floodA flood (in Old English flod a word common to Teutonic languages; compare German Flut Dutch vloed from the same root as is seen in flow, float is an overflow of water, an expanse of water submerging land, a deluge. In the sense of "flowing water", the wor control, two areas that the first settlers to the Northwest were forced to grapple with many times.
In addition, the dams provide water for the Columbia Basin Irrigation ProjectThe Columbia Basin Project is an irrigation project Central Washington State, USA. It provides water for over 600,000 acres (2,400 km˛) of agriculture. History The U. Bureau of Reclamation was created 1902 to aid development of dry western states. Central, one of the most extensive irrigationSahara Irrigation (in agriculture) is the replacement or supplementation of rainfall with water from another source in order to grow crops. In contrast, agriculture that relies only on direct rainfall is sometimes referred to as dryland farming. How it wo projects in the western United States. The project provides water to over 500,000 acres (2,000 km˛) of fertile but arid lands in central Washington state. Water from the project has transformed the region from a wasteland barely able to produce subsistance levels of dry-land wheat crops to a major agricultural center. Important crops include apples, potatoes, alfalfa, wheat, corn (maize), barley, hops, beans, and sugar beets.
There are also contaminants that have seeped into the Columbia River from the Hanford Nuclear Reservation. This Reservation was established in 1940s as part of the Manhattan Project, located along the river in south eastern Washington on 586 mile˛ (1,520 km˛) of some of the most fertile land in North America, but at the time of establishment the area was considered a wasteland. The site served as a plutonium production complex with nine nuclear reactors and related facilities. Most of the facilities were shutdown in the 1960s. The site is currently under control of the Department of Energy, and is currently a CERCLA, or superfund site. The superfund cleanup is expected to be completed in 2030.
In addition to irrigation and electricity, the river also provides entertainment to thousands in the region. The Columbia River Gorge is considered by many windsurfers as the best windsurfing place in the world. Water skiers also enjoy this wide river throughout the summer.
There are also many more major problems that the Columbia River has, from raw sewage dumpage, to hundreds of tons of slag dumped daily. Because of the pollution problems, some people would say the future health of the Columbia River does not look good. However, newspapers such as The Oregonian are calling attention to the problems of rivers. There is hope that humans, industries, and safe water can be made to co-exist.

On May 11, 1792, Captain Robert Gray became the first white man to see the Columbia River. Gray traveled to the Pacific Northwest to trade for fur in a privately-owned vessel named Columbia, and he named the river after the ship. Gray's discovery of the Columbia is thought to have established a stronger "right" of "American" presence in the territory (which had been claimed by Russians, British, and Spanish, among other nations). Lewis and Clark's overland expedition explored the vast, unmapped lands west of the Missouri River. They travelled down the Columbia River to the Pacific Ocean.
