Sea, Ocean. [32] The floods' periodic inundation of the lower Columbia River Plateau deposited rich sediments; 21st-century farmers in the Willamette Valley "plow fields of fertile Montana soil and clays from Washington's Palouse". There are also high levels of mollusk endemism. [28] The modern Cascade Range began to uplift 5 to 4 million years ago. Four mainstem dams and four lower Snake River dams contain navigation locks to allow ship and barge passage from the ocean as far as Lewiston, Idaho. During the Missoula Floods 10,000 to 15,000 years ago, much of the floodwater took a more direct route south, forming the ancient river bed known as the Grand Coulee. [79], On May 12, 1792, Gray returned south and crossed the Columbia Bar, becoming the first known explorer of European descent to enter the river.

The Columbia and its tributaries have been central to the region's culture and economy for thousands of years. [115] Canada agreed to build dams and provide reservoir storage, and the United States agreed to deliver to Canada one-half of the increase in US downstream power benefits as estimated five years in advance. Paper charts for navigation. In 1891 the Columbia was dredged to enhance shipping. The Willamette River channel is 43 feet deep up to approximately river mile 2, from that point the controlling [81] Gray's discovery of the Columbia River was later used by the United States to support its claim to the Oregon Country, which was also claimed by Russia, Great Britain, Spain and other nations. [194] This divide meets the Continental Divide at Snow Dome (also known as Dome), near the northernmost bend of the Columbia River. Grand Teton National Park lies in the watershed, as well as parts of Yellowstone National Park, Glacier National Park, Mount Rainier National Park, and North Cascades National Park. Snake River. It is also the source of irrigation water for central and SE Washington where many crops are grown. Fishing Charter on the Columbia river from Tri cities Washington to Portland Oregon. . [83][84], Because the Columbia was at the same latitude as the headwaters of the Missouri River, there was some speculation that Gray and Vancouver had discovered the long-sought Northwest Passage. By 1957, the eight plutonium production reactors at Hanford dumped a daily average of 50,000 curies of radioactive material into the Columbia. The ecoregion includes the mainstem Columbia north of the Snake River and tributaries such as the Yakima, Okanagan, Pend Oreille, Clark Fork, and Kootenay rivers. The Northwest Forest Plan, a piece of federal legislation from 1994, mandated that timber companies consider the environmental impacts of their practices on rivers like the Columbia. In comparison, the Mississippi drops less than 0.65 feet per mile (12.3 cm/km). [12] The river turns south after the Okanogan River confluence, then southeasterly near the confluence with the Wenatchee River in central Washington. Rounding the northern end of the Selkirk Mountains, the river turns sharply south through a region known as the Big Bend Country, passing through Revelstoke Lake and the Arrow Lakes. Many different Native Americans and First Nations peoples have a historical and continuing presence on the Columbia. Prior to contact with westerners, villages along this 9-mile (14 km) stretch may have at times had a population as great as 10,000. [54] From the earliest contact with westerners, the natives of the mid- and lower Columbia were not tribal, but instead congregated in social units no larger than a village, and more often at a family level; these units would shift with the season as people moved about, following the salmon catch up and down the river's tributaries.[55]. [72] The Yakama were slower to do so, organizing a formal government in 1944. Fish were central to the culture of the region's natives, both as sustenance and as part of their religious beliefs. At one time, the Columbia was one of the top salmon-producing river systems in the world. It is not known how long it took the river to break through the barrier; estimates range from several months to several years. Included Area. For many the final leg of the journey involved travel down the lower Columbia River to Fort Vancouver. A reduced -scale NOAA nautical chart for small boaters When possible, use the full -size NOAA chart for navigation. Click to hide station-specific text Additional Data and Information.--Station data inventory, and annual data report. Celilo Falls, located east of the modern city of The Dalles, was a vital hub for trade and the interaction of different cultural groups,[55] being used for fishing and trading for 11,000 years. No other rivers except for the Klamath and Pit River completely breach the Cascades—the other rivers that flow through the range also originate in or very near the mountains. [199], River in the Pacific Northwest of North America, Columbia River from Rowena Crest Viewpoint with. In many upstream areas cut off from the ocean by dams, sturgeon simply live upstream of the dam. [198] To the north, mostly in British Columbia, the Columbia watershed borders the Fraser River watershed. NOTE: Use the official, full scale NOAA nautical chart for real navigation whenever possible. European and American vessels explored the coastal area around the mouth of the river in the late 18th century, trading with local natives. Vegetation varies widely, ranging from western hemlock and western redcedar in the moist regions to sagebrush in the arid regions. There are so many kinds of fish that anglers chase here. Check reviews and discounted rates for AAA/AARP members, seniors, extended stays & government. [106] In early 2006, the Corps spilled 50 US gallons (190 L) of hydraulic oil into the Columbia, drawing further criticism from environmental organizations. It marks the southern and eastern borders of the Colville Indian Reservation and the western border of the Spokane Indian Reservation. [147], Salmon populations declined dramatically after the establishment of canneries in 1867. [57] As years progressed, the right of natives to fish along the Columbia became the central issue of contention with the states, commercial fishers, and private property owners. The Columbia River is the largest river in the Pacific Northwest, flowing a total of 1,243 miles from British Columbia to the Pacific Ocean. [120] Canada's obligation was met by building three dams (two on the Columbia, and one on the Duncan River), the last of which was completed in 1973. The Mississippi and Nelson watersheds are separated by the Laurentian Divide, which meets the Continental Divide at Triple Divide Peak near the headwaters of the Columbia's Flathead River tributary. Date 1892. USGS 12514400 COLUMBIA RIVER BELOW HWY 395 BRIDGE AT PASCO, WA. [20] A navigation channel reaching to Lewiston, Idaho, along the Columbia and Snake rivers, was completed in 1975. The Deschutes River joins the Columbia near The Dalles. Royal Navy commander George Vancouver sailed past the mouth in April 1792 and observed a change in the water's color, but he accepted Meares' report and continued on his journey northward. By 1980, the summer proportion had been lowered to about 50 percent, essentially eliminating the seasonal pattern. The most recent and significant is known as the Bonneville Slide, which formed a massive earthen dam, filling 3.5 miles (5.6 km) of the river's length. Until 2000, the Northwestern United States produced up to 17 percent of the world's aluminum and 40 percent of the aluminum produced in the United States. [124], The installation of dams dramatically altered the landscape and ecosystem of the river. [129], Many farmers in central Washington build dams on their property for irrigation and to control frost on their crops. In the late 18th century, a private American ship became the first non-indigenous vessel to enter the river; it was followed by a British explorer, who navigated past the Oregon Coast Range into the Willamette Valley. [46] Later that month, Vancouver encountered the American captain Robert Gray at the Strait of Juan de Fuca. Sparked by the 1848 Whitman Massacre, a number of violent battles were fought between American settlers and the region's natives. Along the upper Snake River and Salmon River, the Shoshone Bannock tribes are present. This chart display or derived product can be used as a planning or analysis tool and may not be used as a navigational aid. [160] The Northwest Power Planning Council approved a plan that provided more water for fish and less for electricity, irrigation, and transportation. The central Oregon county of Deschutes is the fastest-growing in the state. [53] From 1805 to 1807, the Lewis and Clark Expedition entered the Oregon Country along the Clearwater and Snake rivers, and encountered numerous small settlements of natives. [52][53] Along with horses came aspects of the emerging plains culture, such as equestrian and horse training skills, greatly increased mobility, hunting efficiency, trade over long distances, intensified warfare, the linking of wealth and prestige to horses and war, and the rise of large and powerful tribal confederacies. Chief Factor John McLoughlin, a physician who had been in the fur trade since 1804, was appointed superintendent of the Columbia District. Posted on Sep 12, 2020. Oral histories describe the formation and destruction of the Bridge of the Gods, a land bridge that connected the Oregon and Washington sides of the river in the Columbia River Gorge. Water quality is also an important factor in the survival of other wildlife and plants that grow in the Columbia River drainage basin. [14], The Deschutes River joins the Columbia near The Dalles. Below the Arrow Lakes, the Columbia passes the cities of Castlegar, located at the Columbia's confluence with the Kootenay River, and Trail, two major population centers of the West Kootenay region. An extensive system of locks allowed ships and barges to pass easily from one reservoir to the next. [130], The Columbia's heavy flow and large elevation drop over a short distance, 2.16 feet per mile (40.9 cm/km), give it tremendous capacity for hydroelectricity generation. In the 1840s a mass migration of American settlers undermined British control. Opening at 8:00 AM. The Columbia River flows through many major cities including Revelstoke, Tri-Cities, Portland [photo below], Vancouver (WA), Longview, and Astoria. As of 2016, the Columbia ranked third, behind the Mississippi and Paraná rivers, among the world's largest export corridors for grain. Era 1881-1920 (Industrialization and Progressive Reform) Record Type Map. The mouth of is the Columbia River at Lake Wallula. The trench is a broad, deep, and long glacial valley between the Canadian Rockies and the Columbia Mountains in BC. Chart 18521 Date of experience: May 2016.

Many ships in the area, especially those under Spanish and British command, searched the northwest coast for a large river that might connect to Hudson Bay or the Missouri River. [10] The river rises in the Rocky Mountains of British Columbia, Canada. [47] The river is known as swah'netk'qhu by the Sinixt people, who live in the area of the Arrow Lakes in the river's upper reaches in Canada. [146] White sturgeon, which take 15 to 25 years to mature, typically migrate between the ocean and the upstream habitat several times during their lives. [76], In 1825, the Hudson's Bay Company (HBC) established Fort Vancouver on the bank of the Columbia, in what is now Vancouver, Washington, as the headquarters of the company's Columbia District, which encompassed everything west of the Rocky Mountains. [166], In southeastern Washington, a 50-mile (80 km) stretch of the river passes through the Hanford Site, established in 1943 as part of the Manhattan Project. They also noted brass teakettles, a British musket, and other artifacts that had been obtained in trade with coastal tribes. NOTE: Use the official, full scale NOAA nautical chart for real navigation whenever possible. [97] Jetties, first constructed in 1886,[92] extend the river's channel into the ocean. Salmon and steelhead return to the streams in which they were born to spawn; where dams prevent their return, entire populations of salmon die. The highest population densities are found west of the Cascade Mountains along the I-5 corridor, especially in the Portland-Vancouver urban area. Hells Canyon, the deepest gorge in North America,[186] and the Columbia Gorge are in the watershed. There are 35 species of fish, of which four are endemic. [65] The annual catch by natives has been estimated at 42 million pounds (19,000 t). Available data for this site . Funding for this site is provided by the cooperators / programs below: US Army Corps of Engineers, Walla Walla District; Station Notes. High elevations have cold winters and short cool summers; interior regions are subject to great temperature variability and severe droughts. 2 of Grant County Final Application for New License, Exhibit B: Project Operation and Resource Utilization", "Treaty Relating to Cooperative Development of the Water Resources of the Columbia River Basin (with Annexes)", "Dams of the Columbia Basin & Their Effects on the Native Fishery", "Celilo Falls and The Dalles Dam Historic Viewer", "Tree-Ring Data Reveals Multiyear Droughts Unlike Any in Recent Memory", "The Columbia River Basin Provides More Than 40% of Total U.S. Hydroelectric Generation", "Three Gorges Dam: The World's Largest Hydroelectric Plant", "BPA Chief to Detail Strategy for Troubled Power Broker", "Hiding in Plain Sight, Google Seeks More Power", "Behold the Server Farm! The Canadian part of the Okanagan subbasin is also growing rapidly. Atmospheric conditions block the flow of moisture in summer, which is generally dry except for occasional thunderstorms in the interior. [66] The most important and productive native fishing site was located at Celilo Falls, which was perhaps the most productive inland fishing site in North America. [78], What happened next would form the basis for decades of both cooperation and dispute between British and American exploration of, and ownership claim to, the region. The Columbia River is magnificent! The depth map made for Washington State only. [22] The lowest flow recorded at The Dalles was 12,100 cubic feet per second (340 m3/s) on April 16, 1968, and was caused by the initial closure of the John Day Dam, 28 miles (45 km) upstream. Instructions: Click icons in the table of contents. Other peoples acquired horses and aspects of the plains culture unevenly. The Columbia Glaciated ecoregion, making up about a third of the total watershed, lies in the north and was covered with ice sheets during the Pleistocene. Absolutely suggested for any visit to the Tri-Cities. [56] The subsequent Indian Wars, especially the Yakima War, decimated the native population and removed much land from native control. The Pend Oreille River system (including its main tributaries, the Clark Fork and Flathead rivers) is also similar in size to the Columbia at their confluence. [186], The World Wide Fund for Nature (WWF) divides the waters of the Columbia and its tributaries into three freshwater ecoregions, naming them Columbia Glaciated, Columbia Unglaciated, and Upper Snake. [77] He named Cape Disappointment for the non-existent river, not realizing the cape marks the northern edge of the river's mouth. This prompted agencies to conduct the first formal financial analysis of hydroelectric development; the reports produced by various agencies were presented in House Document 308. Amazing indoor pool, water slide. [66], In 1957 Celilo Falls was submerged by the construction of The Dalles Dam, and the native fishing community was displaced. [183] The Columbia River estuary exports high rates of nutrients into the Pacific Ocean;[184] with the exception of nitrogen, which is delivered into the estuary by ocean upwelling sources. By that time local communities had become wary of federal hydroelectric projects, and sought local control of new developments; a public utility district in Grant County, Washington, ultimately began construction of the dam at Priest Rapids. [24] The general outline of the Columbia Basin was not complete until between 60 and 40 million years ago, but it lay under a large inland sea later subject to uplift. Individual appropriators must apply for rights to use the reserved waters. [50][51], Horses, originally acquired from Spanish New Mexico, spread widely via native trade networks, reaching the Shoshone of the Snake River Plain by 1700. USGS 12514500 COLUMBIA RIVER ON CLOVER ISLAND AT KENNEWICK, WA. [185], Most of the Columbia's drainage basin (which, at 258,000 square miles or 670,000 square kilometres, is about the size of France)[186] lies roughly between the Rocky Mountains on the east and the Cascade Mountains on the west. The Grand Coulee Dam was the project's central component; upon completion, it pumped water up from the Columbia to fill the formerly dry Grand Coulee, forming Banks Lake. After the floods, the river found its present course, and the Grand Coulee was left dry. The states, Indian tribes, and federal government are all engaged in efforts to restore and improve the water, land, and air quality of the Columbia River drainage basin and have committed to work together to enhance and accomplish critical ecosystem restoration efforts. Major anthropogenic impacts to nutrients in the basin are due to fertilizers from agriculture, sewage systems, logging, and the construction of dams. [36] It has been suggested that if the later dates are accurate there may be a link with the 1700 Cascadia earthquake. [114] With the onset of World War II, the focus of dam construction shifted to production of hydroelectricity. [161] Environmental advocates have called for the removal of certain dams in the Columbia system in the years since. The Columbia River (Upper Chinook: Wimahl or Wimal; Sahaptin: Nch’i-Wàna or Nchi wana; Sinixt dialect swah'netk'qhu) is the largest river in the Pacific Northwest region of North America. Office of Coast Survey . Its watershed of 108,000 square miles (280,000 km2) is larger than the state of Idaho. Colonization schemes were attempted, but failed to match the scale of American settlement. [69] The affected tribes received a $26.8 million settlement for the loss of Celilo and other fishing sites submerged by The Dalles Dam. The Columbia begins its 1,243-mile (2,000 km) journey in the southern Rocky Mountain Trench in British Columbia (BC). The Columbia makes a sharp bend to the west at the Washington–Oregon border. [107] The project includes measures to mitigate environmental damage; for instance, the US Army Corps of Engineers must restore 12 times the area of wetland damaged by the project. [125] Previously active fishing sites, such as Celilo Falls in the eastern Columbia River Gorge, have exhibited a sharp decline in fishing along the Columbia in the last century, and salmon populations have been dramatically reduced. The Columbia River became much of the border between the U.S. territories of Oregon and Washington. Since the late 19th century, public and private sectors have heavily developed the river. [23], When the rifting of Pangaea, due to the process of plate tectonics, pushed North America away from Europe and Africa and into the Panthalassic Ocean (ancestor to the modern Pacific Ocean), the Pacific Northwest was not part of the continent. Columbia River depth map (nautical chart) The marine chart shows water depth and hydrology on an interactive map. The Nez Perce, Cayuse, and Flathead people acquired their first horses around 1730. A can weighing 1 pound (0.45 kg) could be sold for 8d or 9d. [163] Historically, the Snake produced over 1.5 million spring and summer Chinook salmon, a number that has dwindled to several thousand in recent years. [188], Climate varies greatly from place to place within the watershed. Projections for the coming decades assume growth throughout the watershed, including the interior. Available data for this site . [139][140][141] Downriver of Grand Coulee, each dam's reservoir is closely regulated by the Bonneville Power Administration (BPA), the U.S. Army Corps of Engineers, and various Washington public utility districts to ensure flow, flood control, and power generation objectives are met. [180][181], Nutrients dynamics vary in the river basin from the headwaters to the main river and dams, to finally reaching the Columbia River estuary and ocean. [76][80] Gray spent nine days trading near the mouth of the Columbia, then left without having gone beyond 13 miles (21 km) upstream. The Chief Joseph Dam and several dams on the Columbia's tributaries entirely block migration, and there are no migrating fish on the river above these dams. Columbia River, operations for these purposes should also assure that adequate water is available for other water uses. The Columbia receives more than 60 significant tributaries. In that sense, it is reliable. [35][36] Various studies have placed the date of the Bonneville Slide anywhere between 1060 and 1760 AD; the idea that the landslide debris present today was formed by more than one slide is relatively recent and may explain the large range of estimates. E. 1,360,000 acre-feet per year are reserved for projected additional irrigation development of 340,000 acres. Portland-based Northwest Environmental Advocates brought a lawsuit against the Army Corps of Engineers, but it was rejected by the Ninth U.S. The Columbia, Colorado, and Mississippi watersheds meet at Three Waters Mountain in the Wind River Range of Wyoming. [131] In 2012, the river and its tributaries accounted for 29 GW of hydroelectric generating capacity, contributing 44 percent of the total hydroelectric generation in the nation. To the northeast, mostly along the southern border between British Columbia and Alberta, the Continental Divide separates the Columbia watershed from the Nelson-Lake Winnipeg-Saskatchewan watershed, which empties into Hudson Bay. [136] The commoditization of power in the early 21st century, coupled with drought that reduced the generation capacity of the river, damaged the industry and by 2001, Columbia River aluminum producers had idled 80 percent of its production capacity. [191] Annual precipitation varies from more than 100 inches (250 cm) a year in the Cascades to less than 8 inches (20 cm) in the interior. Much of the watershed gets less than 12 inches (30 cm) a year. Chart of the Lower Columbia River. In comparison, the largest run since 1938 was in 1986, with 3.2 million fish entering the Columbia. PROVISIONAL DATA SUBJECT TO REVISION . Columbia River Nautical Charts by NOAA. 18524 - Columbia River Crims Island to Saint Helens 18525 - Columbia River Saint Helens to Vancouver 18526 - Port of Portland, Including Vancouver;Multnomah Channel-southern part Longer-lived isotopes were not affected by this retention, and several terabecquerels entered the river every day. [73] In the 21st century, the Yakama, Nez Perce, Umatilla, and Warm Springs tribes all have treaty fishing rights along the Columbia and its tributaries. [192] Great Basin watersheds that share a border with the Columbia watershed include Harney Basin, Humboldt River, and Great Salt Lake. Irrigation efforts resumed after the war. [22] Flow rates on the Columbia are affected by many large upstream reservoirs, many diversions for irrigation, and, on the lower stretches, reverse flow from the tides of the Pacific Ocean. [29] The exact number of floods is unknown, but geologists have documented at least 40; evidence suggests that they occurred between about 19,000 and 13,000 years ago. Activities at Hanford produced significant quantities of waste containing hazardous chemicals and radioactive materials. The Columbia River is the biggest river in the American West. [165] Other Columbia Basin dams that have been removed include Condit Dam on Washington's White Salmon River, and the Milltown Dam on the Clark Fork in Montana. The Columbia is a cold, powerful river that has claimed lives. The development was accompanied by extensive negotiations between natives and US government agencies.
