Box Canyon Dam is a concrete gravity dam on the Upper Sacramento River impounding Lake Siskiyou reservoir, in Siskiyou County, northern California. [1] [2]
The dam and reservoir are located in Box Canyon of the eastern Trinity Mountains and within the Shasta–Trinity National Forest, southwest of the town of Mount Shasta and Mount Shasta peak.
Box Canyon Dam is 1,100 feet (340 m) long and 209 feet (64 m) high. The dam is owned and operated by Siskiyou County's Flood Control & Water Conservation District and Siskiyou Power Authority, and was completed in 1965 to provide flood control. [3] In 1965, a powerhouse was installed to provide hydroelectric power. [4]
Beginning in April 1959, the State of California appropriated funding to study the feasibility of building the dam. [5]
The Box Canyon Trail begins on the north side of Box Canyon Dam, following the Upper Sacramento River down the narrow canyon to the outskirts of the town of Mount Shasta. [6] The Lake Siskiyou Trail encircles the lake, including a crossing atop the dam. [7] [8]
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 Shasta Cascade region of California is located in the northeastern and north-central sections of the state bordering Oregon and Nevada, including far northern parts of the Central Valley and the Sierra Nevada mountain range.
Shasta Dam is a concrete arch-gravity dam across the Sacramento River in Northern California in the United States. At 602 feet (183 m) high, it is the eighth-tallest dam in the United States. Located at the north end of the Sacramento Valley, Shasta Dam creates Shasta Lake for long-term water storage, flood control, hydroelectricity and protection against the intrusion of saline water. The largest reservoir in the state, Shasta Lake can hold about 4,500,000 acre-feet (5,600 GL).
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.
The McCloud River is a 77.1-mile (124.1 km) long river that flows east of and parallel to the upper Sacramento River, in Siskiyou County and Shasta County in northern California in the United States. Protected under California's Wild and Scenic Rivers Act (1972), it drains a scenic mountainous area of the Cascade Range, including part of Mount Shasta. It is a tributary of the Pit River, which in turn flows into the Sacramento River. The three rivers join in Shasta Lake, formed by Shasta Dam north of Redding.
The Shasta River is a tributary of the Klamath River, approximately 58 miles (93 km) long, in northern California in the United States. It drains the Shasta Valley on the west and north sides of Mount Shasta in the Cascade Range.
Shasta Lake, also popularly known as Lake Shasta, is a reservoir in Shasta County, California, United States. It began to store water in 1944 due to the impounding of the Sacramento River by Shasta Dam, the ninth tallest dam in the United States.
Clear Creek is a tributary of the upper Sacramento River in northern 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 Shasta–Trinity National Forest is a federally designated forest in northern California, United States. It is the largest National Forest in California and is managed by the U.S. Forest Service. The 2,210,485 acre forest encompasses five wilderness areas, hundreds of mountain lakes and 6,278 miles (10,103 km) of streams and rivers. Major features include Shasta Lake, the largest man-made lake in California and Mount Shasta, elevation 14,179 feet (4,322 m).
The Trinity Mountains are a subrange of the Klamath Mountains, one of the ranges within the California Coast Ranges and part the greater Pacific Coast Ranges, the coastal mountain system extending from Mexico to Alaska. The Trinity Mountains subrange rises in Siskiyou County and eastern Trinity County, Northern California.
Hell Hole Reservoir is an artificial, crescent-shaped lake in the Sierra Nevada mountain range 10 miles (16 km) west of Lake Tahoe in California, United States. The lake is about 3.5 miles (5.6 km) long when at full capacity.
Whiskeytown Lake is a reservoir in Shasta County in northwestern California, United States, about 8 miles (13 km) west of Redding. The lake is in the Whiskeytown Unit of the Whiskeytown-Shasta-Trinity National Recreation Area.
Lake Siskiyou is a reservoir formed by Box Canyon Dam on the Sacramento River, in far northern California, near the town of Mt. Shasta, California. It is the site of local recreation, as well as being used for watershed protection and flood control.
Lewiston Lake is a reservoir impounded by Lewiston Dam on the Trinity River, in Trinity County, California.
Spring Creek Debris Dam is an earthfill dam on Spring Creek, a tributary of the Sacramento River, in Shasta County in the U.S. state of California. Completed in 1963, the dam, maintained by the U.S. Bureau of Reclamation, serves primarily to collect severe acid mine drainage stemming from the Iron Mountain Mine. The dam forms the Spring Creek Reservoir, less than 1 mile (1.6 km) long. Spring Creek and South Fork Spring Creek flow into the reservoir from a 16-square-mile (41 km2) watershed. The dam is directly upstream from the city of Keswick, California and the Keswick Reservoir. The operation is part of the Trinity River Division of the Central Valley Project.
The American River is a 30-mile-long (50 km) river in California that runs from the Sierra Nevada mountain range to its confluence with the Sacramento River in downtown Sacramento. Via the Sacramento River, it is part of the San Francisco Bay watershed. This river is fed by the melting snowpack of the Sierra Nevada and its many headwaters and tributaries, including the North Fork American River, the Middle Fork American River, and the South Fork American River.
Keswick Dam is a concrete gravity dam on the Sacramento River about 2 miles (3.2 km) northwest of Redding, California. Part of the U.S. Bureau of Reclamation's Central Valley Project, the dam is 157 feet (48 m) high and impounds the Keswick Reservoir, which has a capacity of 23,800 acre⋅ft (29,400,000 m3). The dam's power plant has three turbines with a generating capacity of 117 megawatts (MW), which, in 1992, was uprated from its original 75 MW. The dam and reservoir serve as an afterbay to regulate peaking power releases from the Shasta Dam upstream.
Iron Canyon Dam is a dam in Shasta County, California, United States.
The Upper North Fork Feather River Project is a hydroelectric scheme in the Sierra Nevada of California, within Lassen and Plumas Counties. The project consists of three dams, five power plants, and multiple conduits and tunnels in the headwaters of the North Fork Feather River, a major tributary of the Feather—Sacramento River systems. The total installed capacity is 362.3 megawatts (MW), producing an annual average of 1,171.9 gigawatt hours (GWh). The project is also contracted for the delivery of irrigation water between March 31 and October 31 of each year. The project is owned and operated by Pacific Gas and Electric Company.
