Hanford Reach
The Hanford Reach is a free-flowing section of the Columbia River, around long, in eastern Washington state. It is named after a large northward bend in the river's otherwise southbound course. Hanford Reach is the only section of the Columbia in the United States that is not tidal nor part of a reservoir, excluding a short reach between the Canada–United States border and the upper end of Franklin D. Roosevelt Lake, the reservoir of Grand Coulee Dam. Much of the Hanford Reach flows through the Hanford Site, a nuclear production facility established during World War II. It is also the site of the Hanford Reach National Monument, created from the original protection area around the Hanford Site. Upstream of the Hanford Reach is Priest Rapids Dam and downstream is the McNary Dam, which also impounds the last stretch of the Snake River, the largest tributary of the Columbia. The Hanford Reach includes the still extant Coyote Rapids and supports over forty species of fish includi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hanford Reach National Monument
The Hanford Reach National Monument is a national monument in the U.S. state of Washington. It was created in 2000, mostly from the former security buffer surrounding the Hanford Nuclear Reservation. The area has been untouched by development or agriculture since 1943. Because of that it is considered an involuntary park. The monument is named after the Hanford Reach, the last non-tidal, free-flowing section of the Columbia River in the United States, and is one of eight National Monuments administered by the U. S. Fish and Wildlife Service; part of the monument within the Hanford Site is also managed by the Department of Energy. President Bill Clinton established the monument by presidential decree in 2000. In May 2017, the Interior Department announced that Hanford Reach was one of 27 National Monuments under review for possible rescinding of their designation.

Ringold Formation
The Ringold Formation is a geologic formation in Eastern Washington, United States. The formation consists of sediment laid down by the Columbia River following the flood basalt eruptions of the Columbia River Basalt Group, and reaches up to thick in places. It preserves fossils dating back to the Neogene period. Exposures of the Ringold Formation can be found from Hanford Reach National Monument north to the Moses Lake area. Large portions of the formation are buried by other sediment deposits, extending as far as Wallula Gap southeast of Kennewick. In recent years, irrigation water entering the groundwater system has destabilized some Ringold Formation slopes and cliffs, causing landslides. The formation was named in 1917 for a school of the same name that existed at the time. Ringold School was located on the Franklin County side of the Columbia River to the south of Savage Island. Geology During the flood basalt eruptions before the sediments were laid down, the Columbia R ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Locke Island
Locke Island is an island located in the Hanford Reach of the Columbia River in Washington, United States. The island is protected as part of the Hanford Reach National Monument, which was created out of lands surrounding the Hanford Site. The island is an important archeological site and is on the National Register of Historic Places. These cultural resources are being threatened by erosion resulting from a landslide changing the river's course. History Human habitation and use of Locke Island has varied significantly throughout time. Before the arrival of European settlers, Native Americans used the island and areas around it for fishing and other river-based activities. Use of the island largely ceased as Americans moved into the region and began to farm on both sides of the Columbia River, establishing the town of White Bluffs on the Benton County side of the river. This town, which was only a few miles south of Locke Island, was abandoned when the Hanford Site was construct ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chinook Salmon
The Chinook salmon (''Oncorhynchus tshawytscha'') is the largest and most valuable species of Pacific salmon in North America, as well as the largest in the genus ''Oncorhynchus''. Its common name is derived from the Chinookan peoples. Other vernacular names for the species include king salmon, Quinnat salmon, Tsumen, spring salmon, chrome hog, Blackmouth, and Tyee salmon. The scientific species name is based on the Russian common name ''chavycha'' (чавыча). Chinook are anadromous fish native to the North Pacific Ocean and the river systems of western North America, ranging from California to Alaska, as well as Asian rivers ranging from northern Japan to the Palyavaam River in the Arctic northeast Siberia. They have been introduced to other parts of the world, including New Zealand, thriving in Lake Michigan Great Lakes of North America and Michigan's western rivers, and Patagonia. A large Chinook is a prized and sought-after catch for a sporting angler. The flesh of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Rapids Of The Columbia River
This is a list of rapids of the Columbia River, listed in upriver order. The river flows through Canada and the United States. Almost all of these rapids are now submerged in the reservoirs of dams. The list is not exhaustive; there were numerous minor rapids and riffles, many of which were never named. Mouth to Snake River * Cascade Rapids (The Cascades, Grand Rapids, Cascade Falls, Cascades of the Columbia): Located at river mile 146.5 near today's Bonneville Dam in the Columbia River Gorge; at .

Snake River
The Snake River is a major river of the greater Pacific Northwest region in the United States. At long, it is the largest tributary of the Columbia River, in turn, the largest North American river that empties into the Pacific Ocean. The Snake River rises in western Wyoming, then flows through the Snake River Plain of southern Idaho, the rugged Hells Canyon on the Oregon–Idaho border and the rolling Palouse Hills of Washington (state), Washington, emptying into the Columbia River at the Tri-Cities, Washington, Tri-Cities in the Columbia Basin of Eastern Washington. The Snake River drainage basin encompasses parts of six U.S. states (Idaho, Washington, Oregon, Utah, Nevada, and Wyoming) and is known for its varied geologic history. The Snake River Plain was created by a volcanic hotspot (geology), hotspot which now lies underneath the Snake River headwaters in Yellowstone National Park.

Hanford Site
The Hanford Site is a decommissioned nuclear production complex operated by the United States federal government on the Columbia River in Benton County in the U.S. state of Washington. The site has been known by many names, including SiteW and the Hanford Nuclear Reservation. Established in 1943 as part of the Manhattan Project, the site was home to the Hanford Engineer Works and B Reactor, the first full-scale plutonium production reactor in the world. Plutonium manufactured at the site was used in the first atomic bomb, which was tested in the Trinity nuclear test, and in the Fat Man bomb that was used in the bombing of Nagasaki. During the Cold War, the project expanded to include nine nuclear reactors and five large plutonium processing complexes, which produced plutonium for most of the more than sixty thousand weapons built for the U.S. nuclear arsenal. Nuclear technology developed rapidly during this period, and Hanford scientists produced major technological ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Washington (state)
Washington (), officially the State of Washington, is a state in the Pacific Northwest region of the Western United States. Named for George Washington—the first U.S. president—the state was formed from the western part of the Washington Territory, which was ceded by the British Empire in 1846, by the Oregon Treaty in the settlement of the Oregon boundary dispute. The state is bordered on the west by the Pacific Ocean, Oregon to the south, Idaho to the east, and the Canadian province of British Columbia to the north. It was admitted to the Union as the 42nd state in 1889. Olympia is the state capital; the state's largest city is Seattle. Washington is often referred to as Washington state to distinguish it from the nation's capital, Washington, D.C. Washington is the 18th-largest state, with an area of , and the 13th-most populous state, with more than 7.7 million people. The majority of Washington's residents live in the Seattle metropolitan area, the center of trans ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grand Coulee Dam
Grand Coulee Dam is a concrete gravity dam on the Columbia River in the U.S. state of Washington, built to produce hydroelectric power and provide irrigation water. Constructed between 1933 and 1942, Grand Coulee originally had two powerhouses. The third powerhouse ("Nat"), completed in 1974 to increase energy production, makes Grand Coulee the largest power station in the United States by nameplate-capacity at 6,809 MW. The proposal to build the dam was the focus of a bitter debate during the 1920s between two groups. One group wanted to irrigate the ancient Grand Coulee with a gravity canal while the other pursued a high dam and pumping scheme. The dam supporters won in 1933, but, although they fully intended otherwise, the initial proposal by the Bureau of Reclamation was for a "low dam" tall which would generate electricity without supporting irrigation. That year, the U.S. Bureau of Reclamation and a consortium of three companies called MWAK (Mason-Walsh-Atkinson Kier ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
