The Sacramento River is the principal river of Northern California in the United States and is the largest river in California. Rising in the Klamath Mountains, the river flows south for 400 miles (640 km) before reaching the Sacramento–San Joaquin River Delta and San Francisco Bay. The river drains about 26,500 square miles (69,000 km2) in 19 California counties, mostly within the fertile agricultural region bounded by the Coast Ranges and Sierra Nevada known as the Sacramento Valley, but also extending as far as the volcanic plateaus of Northeastern California. Historically, its watershed has reached as far north as south-central Oregon where the now, primarily, endorheic (closed) Goose Lake rarely experiences southerly outflow into the Pit River, the most northerly tributary of the Sacramento.
The Klamath River flows 257 miles (414 km) through Oregon and northern California in the United States, emptying into the Pacific Ocean. By average discharge, the Klamath is the second largest river in California after the Sacramento River. Its nearly 16,000-square-mile (41,000 km2) watershed stretches from the high desert of south-central Oregon to the temperate rainforest of the North Coast. Unlike most rivers, the Klamath begins in a desert region and flows through the rugged Cascade Range and Klamath Mountains before reaching the ocean; National Geographic magazine has called the Klamath "a river upside down".
The Rogue River in southwestern Oregon in the United States flows about 215 miles (346 km) in a generally westward direction from the Cascade Range to the Pacific Ocean. Known for its salmon runs, whitewater rafting, and rugged scenery, it was one of the original eight rivers named in the Wild and Scenic Rivers Act of 1968. Beginning near Crater Lake, which occupies the caldera left by the explosive volcanic eruption and collapse of Mount Mazama, the river flows through the geologically young High Cascades and the older Western Cascades, another volcanic province. Further west, the river passes through multiple exotic terranes of the more ancient Klamath Mountains. In the Kalmiopsis Wilderness section of the Rogue basin are some of the world's best examples of rocks that form the Earth's mantle. Near the mouth of the river, the only dinosaur fragments ever discovered in Oregon were found in the Otter Point Formation, along the coast of Curry County.
The Chinook salmon is the largest and most valuable species of Pacific salmon. 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).
Lake Oroville is a reservoir formed by the Oroville Dam impounding the Feather River, located in Butte County, northern California. The lake is situated 5 miles (8 km) northeast of the city of Oroville, within the Lake Oroville State Recreation Area, in the western foothills of the Sierra Nevada. Known as the second-largest reservoir in California, Lake Oroville is treated as a keystone facility within the California State Water Project by storing water, providing flood control, recreation, freshwater releases to assist in controlling the salinity intrusion into the Sacramento-San Joaquin Delta and protecting fish and wildlife.
The Link River Dam is a concrete gravity dam on the Link River in the city of Klamath Falls, Oregon, United States. It was built in 1921 by the California Oregon Power Company (COPCO), the predecessor of PacifiCorp, which continues to operate the dam. The dam is owned by the U.S. Bureau of Reclamation.
The Klamath Project is a water-management project developed by the United States Bureau of Reclamation to supply farmers with irrigation water and farmland in the Klamath Basin. The project also supplies water to the Tule Lake National Wildlife Refuge, and the Lower Klamath National Wildlife Refuge. The project was one of the first to be developed by the Reclamation Service, which later became the Bureau of Reclamation.
Condit Hydroelectric Project was a development on the White Salmon River in the U.S. state of Washington. It was completed in 1913 to provide electrical power for local industry, and is listed in the National Register of Historic Places as an engineering and architecture landmark.
The Klamath Basin is the region in the U.S. states of Oregon and California drained by the Klamath River. It contains most of Klamath County and parts of Lake and Jackson counties in Oregon, and parts of Del Norte, Humboldt, Modoc, Siskiyou, and Trinity counties in California. The 15,751-square-mile (40,790 km2) drainage basin is 35% in Oregon and 65% in California. In Oregon, the watershed typically lies east of the Cascade Range, while California contains most of the river's segment that passes through the mountains. In the Oregon-far northern California segment of the river, the watershed is semi-desert at lower elevations and dry alpine in the upper elevations. In the western part of the basin, in California, however, the climate is more of temperate rainforest, and the Trinity River watershed consists of a more typical alpine climate.
The Elwha Ecosystem Restoration Project is a 21st-century project of the U.S. National Park Service to remove two dams on the Elwha River on the Olympic Peninsula in Washington state, and restore the river to a natural state. It is the largest dam removal project in history and the second largest ecosystem restoration project in the history of the National Park Service, after the Restoration of the Everglades. The controversial project, costing about $351.4 million, has been contested and periodically blocked for decades. It has been supported by a major collaboration among the Lower Elwha Klallam Tribe, and federal and state agencies.
The John C. Boyle Dam was a hydroelectric dam located in southern Oregon, United States. It is on the upper Klamath River, south (downstream) of Keno, and about 12 miles (19 km) north of the California border. Originally developed and known as Big Bend, the John C. Boyle dam and powerhouse complex was re-dedicated to honor the pioneer hydroelectric engineer who was responsible for the design of virtually all of the Klamath Hydroelectric Project.
The Klamath River is a river in southern Oregon and northern California in the United States. This article describes its course.
The 2002 Klamath River fish kill occurred on the Klamath River in California in September 2002. According to the official estimate of mortality, about 34,000 fish died. Though some counts may estimate over 70,000 adult chinook salmon were killed when returning to the river to spawn, making it the largest salmon kill in the history of the Western United States. Besides the chinook salmon, other fish that perished include: steelhead, coho salmon, sculpins, speckled dace, and Klamath smallscale sucker.
Copco Lake was an artificial lake on the Klamath River in Siskiyou County, California, near the Oregon border. The lake's waters were impounded by the Copco Number 1 Dam, which was completed in 1922 as part of the Klamath River Hydroelectric Project.
John C. Boyle Reservoir is an artificial impoundment behind John C. Boyle Dam on the Klamath River in the U.S. state of Oregon. The lake is 16 miles (26 km) west-southwest of Klamath Falls along Oregon Route 66.
The Klamath Basin Restoration Agreement (KBRA) is an American multi-party legal agreement determining river usage and water rights involving the Klamath River and Klamath Basin in the states of California and Oregon. Discussion of the KBRA began in 2005. Congress failed to pass legislation that would implement the KBRA by the January 1, 2016 deadline.
The Klamath River Hydroelectric Project was a series of hydroelectric dams and other facilities on the mainstem of the Klamath River, in a watershed on both sides of the California-Oregon border.
The Klamathon Fire was a wildfire in Siskiyou County south of Hornbrook, California in the United States. The fire was reported on July 5, 2018 and was contained on July 21, after burning 38,008 acres (154 km2). The fire threatened private timber lands along the California-Oregon border; public lands in the Klamath National Forest; Rogue River-Siskiyou National Forest; Jackson County, Oregon; communities of Hornbrook and Hilt, California; and Colestin, Oregon. It destroyed 82 structures, damaged 12 structures, injured three firefighters, and killed one civilian.
Un-Dam the Klamath (#UnDamtheKlamath) is a social movement in the United States to remove the dams on the Klamath River primarily because they obstruct salmon, steelhead, and other species of fish from accessing the upper basin which provides hundreds of miles of spawning habitat. The dams have also significantly harmed Native American communities such as the Hupa, Karuk, Klamath, and Yurok. Four hydroelectric dams on the Klamath River in California and Oregon are being advocated for removal.
