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. It drains an extensive watershed of almost 16,000 square miles (41,000 km2) that stretches from the arid country of south-central Oregon to the temperate rainforest of the Pacific coast. Unlike most rivers, the Klamath begins in the high desert and flows toward the mountains – carving its way through the rugged Cascade Range and Klamath Mountains before reaching the sea. The upper basin, today used for farming and ranching, once contained vast freshwater marshes that provided habitat for abundant wildlife, including millions of migratory birds. Most of the lower basin remains wild, with much of it designated wilderness. The watershed is known for this peculiar geography, and the Klamath has been called "a river upside down" by National Geographic magazine.
The Pit River is a major river draining from northeastern California into the state's Central Valley. The Pit, the Klamath and the Columbia are the only three rivers in the U.S. that cross the Cascade Range.
Lost River begins and ends in a closed basin in northern California and southern Oregon in the United States. The river, 60 miles (97 km) long, flows in an arc from Clear Lake Reservoir in Modoc County, California, through Klamath County, Oregon, to Tule Lake in Siskiyou County, California. About 46 mi (74 km) of Lost River are in Oregon, and 14 miles (23 km) are in California.
Trinity Dam is an earthfill dam on the Trinity River located about 7 miles (11 km) northeast of Weaverville, California in the United States. The dam was completed in the early 1960s as part of the federal Central Valley Project to provide irrigation water to the arid San Joaquin Valley.
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.
Clear Lake Reservoir is a reservoir in the Klamath Basin and the Modoc National Forest, in northwestern Modoc County, California.
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.
Ah Pah Dam was a proposed dam on the Klamath River in the U.S. state of California proposed by the United States Bureau of Reclamation as part of its United Western Investigation study in 1951. It was to have been 813 feet (248 m) high and was to be located 12 miles (19 km) upstream of the river's mouth. It would stand almost as tall as the Transamerica Pyramid building in San Francisco, but would be much more massive. It would flood 40 miles (64 km) of the Trinity River, including the Yurok, Karuk and Hupa Indian Reservations, the lower Salmon River, and 70 miles (110 km) of the Klamath River, creating a reservoir with a volume of 15,000,000 acre-feet (19 km3) – two-thirds of the size of Lake Mead, and becoming the largest reservoir in California. The water would flow by gravity through a tunnel 60 miles (97 km) long to the Sacramento River just above Redding and onward to Southern California, in an extreme diversion plan known as the Klamath Diversion. The tunnel would have been located near the southernmost extent of the reservoir. It was named in the language of the Yurok people.
Bully Creek Reservoir is a reservoir in Malheur County of the U.S. state of Oregon. It is an impoundment of Bully Creek, a tributary of the Malheur River.
The Klamath Diversion was a federal water project proposed by the U.S. Bureau of Reclamation in the 1950s. It would have diverted the Klamath River in Northern California to the more arid central and southern parts of that state. It would relieve irrigation water demand and groundwater overdraft in the Central Valley and boost the water supply for Southern California. Through the latter it would allow for other Southwestern states—Arizona, Nevada, New Mexico and Utah—as well as Mexico to receive an increased share of the waters of the Colorado River.
The Klamath River is a river in southern Oregon and northern California in the United States. This article describes its course.
The Cascade Canal is a canal located in Klamath and Jackson counties, in the U.S. State of Oregon. It delivers water from Fourmile Lake in the Klamath River watershed over the Cascade Divide to Fish Lake in the Rogue River watershed. It diverts approximately 5,462 acre-feet (6,737,000 m3) annually into Fish Lake. About 33 percent of the water diverted from Fourmile Lake is lost or spilled on the way to Fish Lake.
Dickinson Dam is a dam in Stark County, North Dakota, one and a half miles west of the town of Dickinson.
Big Sandy Dam is a dam in Sweetwater County, Wyoming, about ten miles north of Farson.
Box Butte Dam is a dam in the arid northwestern panhandle area of Dawes County, Nebraska.
Bonny Dam is a dam in Yuma County, Colorado, in the eastern part of the state.
Ady is an unincorporated historic locale in Klamath County, Oregon, United States.
Miller Creek is a 7.6-mile-long (12.2 km) stream in western Klamath County, Oregon, United States. It originates above Gerber Reservoir and empties into irrigation canals within Langell Valley southeast of Bonanza and finally into the Lost River.
Gerber Reservoir is an irrigation impoundment created by Gerber Dam. It is located in southern Klamath County, Oregon, United States. The reservoir covers 3,815 acres (1,544 ha). The dam and reservoir are named in honor of Louis C. Gerber, an early pioneer who owned much of the land flooded by the reservoir. Today, the reservoir and surrounding property is owned by the United States Government. It is administered by the Bureau of Reclamation and the Bureau of Land Management. Gerber Reservoir is a popular outdoor recreation site with two campgrounds along its west shore.
