Furthermore, by creating a constant flow and consistent depth along the river channel, the series of locks and dams have allowed for Lewiston, Idaho, to become the furthest inland seaport on the west coast of the United States. Dams are listed in order from headwater (near Castle Mountain, Beaverfoot Range, BC) to mouth (Columbia River, BC). Dam was initially completed in 1961 with three generators online. It is fish and the dams’ impact on them, especially salmon, that triggered the meeting—one of 15 the agencies held throughout the Columbia River Basin. The Columbia River Basin is North America's fourth largest, draining about 250,000 square miles and extending throughout the Pacific Northwest and into Canada. As can be seen in the lists, these dams provide many tens of gigawatts of power. Dams are listed in order from headwater (Timpanogas Lake, OR) to mouth (Willamette River, OR). Initially constructed by Greater Shoshone and Twin Falls Water Power Company in 1910, bought by Idaho Power in 1916 and updated in 1949. The dams are listed in the order as they are found from source to terminus. Many of the dams in the Columbia River watershed were not created for … For website corrections, write to cenwd-pa@usace.army.mil. Grand Coulee Dam is the largest producer of hydroelectric power in the United States,[1] generating 6,809 megawatts, over one-sixth of all power in the basin. Beginning in 1892, dams were constructed at the mouth of Lake Chelan. Averaging a major dam every 72 miles (116 km), the rivers in the Columbia watershed combine to generate over 36,000 megawatts of power, with the majority coming on the main stem. Home Page > Washington State Maps > Map of the Columbia River basin with dams highlighted.

Dam and units one to four completed in 1959, unit five completed in 1980.

Additional dams were built at the north and south ends of Grand Coulee, the dry canyon south of Grand Coulee Dam, allowing the coulee to be filled with water pumped up from the Columbia River. The US Army Corps of Engineers operates nine of 10 major federal projects on the Columbia and Snake rivers, and Dworshak Dam on the Clearwater River, Libby Dam on the Kootenai River, and Albeni Falls Dam on the Pend Oreille River. Dams are listed in order from headwater (Columbia Lake, BC) to mouth (Pacific Ocean, OR/WA). Major dam construction began in the early 20th century and picked up the pace after the Columbia River Treaty in the 1960s, by the mid 1980s all the big dams were finished. Powerhouse units four through six were later added and online in 1976. Dams are listed in order from headwaters (near Mount Daniel, WA) to mouth (Yakima River, WA). The organization of the following lists begins with the Columbia River dams and is followed by dams on its tributaries (in order of length) and their respective watersheds. Use this interactive map to learn about the Columbia River system including Columbia River Treaty dams, reservoirs and pre-dam water levels. Kootenay Canal Generating Station is located at the end of a canal created by the Corra Linn Dam. A new power plant was built in the 1990s; this one was decommissioned and turned into a historical display. Original dam was completed in 1927. There are more than 250 reservoirs and around 150 hydroelectric projects in the basin, including 18 mainstem dams on the Columbia and its main tributary, the Snake River. Altogether, a total of 11 dams have been built on the river in the United States as it winds its way from the Canadian border toward the Pacific Ocean; Grand Coulee Dam is the keystone of the Columbia River system dams. This map allows you to explore the Columbia River Basin and changes that have occurred since construction of Columbia River Treaty Dams. There are more than 250 reservoirs and around 150 hydroelectric projects in the basin, including 18 mainstem dams on the Columbia and its main tributary, the Snake River. [n 19], Dams are listed in order from headwater (Confluence of North Fork and Middle Fork Flathead River) to mouth (Clark Fork River). Dams are listed in order from headwaters (confluence of North Santiam and South Santiam rivers) to mouth (Willamette River, OR).

Dam and first three powerhouses were completed in 1975. Dams are listed in order from headwater (Confluence of Big River and Garoutte Creek, OR) to mouth (Willamette River). In addition to providing ample power for the people of the Pacific Northwest, the reservoirs created by the dams have created numerous recreational opportunities, including fishing, boating, and windsurfing. Many of the dams in the Columbia River watershed were not created for the specific purposes of water storage or flood protection. The Corps operates a series of eight dams on the lower Columbia and Snake rivers that affect the habitat and migration of anadromous salmon and steelhead species.

Tributaries of the Columbia River and their dammed tributaries, as well as the main stem itself, each have their own list below.

Dam was initially completed in 1941; third power plant was begun in 1967 and completed in 1974. Although these rivers are not one, for the simplification of this list they will be listed together, as they are only separated by Lake Pend Oreille.

Altogether, a total of 11 dams have been built on the river in the United States as it winds its way from the Canadian border toward the Pacific Ocean; Grand Coulee Dam is the keystone of the Columbia River system dams. 1. [n 21]. The federal projects are a major source of power in the region, and provide flood damage reduction, navigation, recreation, fish and wildlife, municipal and industrial water supply, and irrigation benefits. After the aggregate was found to be of poor quality, a new concrete, thin arch dam was completed in 1969, doubling the size of the reservoir.

[2] Despite the numerous benefits to humans that the dams have provided, a number of environmental consequences have manifested as a result of the dams, including a negative impact on salmonid populations of the basin.[3].

Zoom in and out to see more or less detail. All forks of Flathead River are treated as being on main stem, as there is only one dam on any of the forks.
