Soldier Creek Dam is an earthen dam on the Strawberry River, located within the Uinta National Forest in southern Wasatch County, Utah, United States.
The dam forms Strawberry Reservoir and is a principal feature of the Strawberry Valley Project, part of the Bonneville Unit of the Central Utah Project. The dam and reservoir were built and operated by the United States Bureau of Reclamation (USBR). [3]
Constructed between 1970 and 1974, the dam replaced the earlier Strawberry Dam, built slightly upstream of the current site from 1911 to 1913. The new dam increased the storage capacity of Strawberry Reservoir from 283,000 acre-feet (0.349 km3) to more than 1,120,000 acre-feet (1.38 km3). [4] The primary purpose of the dam is to store flows from the upper Strawberry River, as well as water diverted from eight tributaries of the Duchesne River, for diversion through the Strawberry Tunnel to supplement water supplies in the Utah Valley. Water from the Strawberry Tunnel eventually outlets into Sixth Water Canyon, the Diamond Fork (stream) and finally the Spanish Fork (river) before flowing into Utah Lake. [3] [5]
Soldier Creek Dam is a zoned earthfill embankment 272 feet (83 m) high and 1,290 feet (390 m) long, with a structural volume of 3,206,000 cubic yards (2,451,000 m3). [1] Water releases from the dam are controlled by outlet works with a bypass capacity of 2,830 cu ft/s (80 m3/s). The dam controls runoff from a drainage area of 170 square miles (440 km2). [6]
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 Colorado–Big Thompson Project is a federal water diversion project in Colorado designed to collect West Slope mountain water from the headwaters of the Colorado River and divert it to Colorado's Front Range and plains. In Colorado, approximately 80% of the state's precipitation falls on the West Slope, in the Rocky Mountains, while around 80% of the state's growing population lives along the eastern slope, between the cities of Fort Collins and Pueblo.
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.
Flaming Gorge Dam is a concrete thin-arch dam on the Green River, a major tributary of the Colorado River, in northern Utah in the United States. Flaming Gorge Dam forms the Flaming Gorge Reservoir, which extends 91 miles (146 km) into southern Wyoming, submerging four distinct gorges of the Green River. The dam is a major component of the Colorado River Storage Project, which stores and distributes upper Colorado River Basin water.
Strawberry Reservoir is a large reservoir in the U.S. state of Utah. It is Utah's most popular fishery, receiving over 1.5 million angling hours annually and is part of the Blue Ribbon Fisheries program. Game fish in the reservoir include sterilized rainbow trout, bear lake cutthroat trout, kokanee salmon and crayfish. It is located 23 miles (37 km) southeast of Heber, Utah on U.S. Route 40. The reservoir is situated in Strawberry Valley. This valley is normally part of the Colorado River drainage. The dam was constructed to divert water into Utah Valley.
The Central Utah Project is a US federal water project that was authorized for construction under the Colorado River Storage Project Act of April 11, 1956, as a participating project. In general, the Central Utah Project develops a portion of Utah's share of the yield of the Colorado River, as set out in the Colorado River Compact of 1922.
In Section 203(a) of the Central Utah Project Completion Act, the United States Congress authorized a federally authorized and funded replacement project to replace the Uinta and Upalco Units of the Central Utah Project (CUP) which were not constructed. The replacement project is the Uinta Basin Replacement Project (UBRP). The UBRP will provide: 2,500 acre-feet (3,100,000 m3) of irrigation water; 3,000 acre-feet (3,700,000 m3) of municipal and industrial water; reduced wilderness impacts; increased instream flows; and improved recreation. Design work began in 2002. Construction began in 2004 and is anticipated to be completed in 2011. The Central Utah Water Conservancy District is responsible for construction. The United States Department of the Interior oversees funding and compliance with law and environmental regulation.
The Colorado River Storage Project is a United States Bureau of Reclamation project designed to oversee the development of the upper basin of the Colorado River. The project provides hydroelectric power, flood control and water storage for participating states along the upper portion of the Colorado River and its major tributaries.
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.
Whiskeytown Dam is an earthfill dam on Clear Creek, a tributary of the Sacramento River of northern California in the United States.
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 Duchesne River, located in the Uintah Basin region of Utah in the western United States, is a tributary of the Green River. The watershed of the river covers the Northeastern corner of Utah. The Duchesne River is 115 miles (185 km) long, and drains a total land area of 3,790 square miles (9,800 km2).
The Minidoka Project is a series of public works by the U.S. Bureau of Reclamation to control the flow of the Snake River in Wyoming and Idaho, supplying irrigation water to farmlands in Idaho. One of the oldest Bureau of Reclamation projects in the United States, the project involves a series of dams and canals intended to store, regulate and distribute the waters of the Snake, with electric power generation as a byproduct. The water irrigates more than a million acres (4,000 km²) of otherwise arid land, producing much of Idaho's potato crop. Other crops include alfalfa, fruit and sugar beets. The primary irrigation district lies between Ashton in eastern Idaho and Bliss in the southwestern corner of the state. Five main reservoirs collect water, distributing it through 1,600 miles (2,600 km) of canals and 4,000 miles (6,400 km) of lateral distribution ditches.
The Middle Fork American River is one of three forks that form the American River in Northern California. It drains a large watershed in the high Sierra Nevada west of Lake Tahoe and northeast of Sacramento in Placer and El Dorado Counties, between the watersheds of the North Fork American River and South Fork American River. The Middle Fork joins with the North Fork near Auburn and they continue downstream to Folsom Lake as the North Fork, even though the Middle Fork carries a larger volume of water.
Lake Sherburne Dam is a 107-foot (33 m) high compacted earthfill dam built between 1914 and 1921 built just outside the boundary of Glacier National Park, Montana, its reservoir extending into the park. The dam impounds Swiftcurrent Creek as it flows out of the park. Water stored in Lake Sherburne is released to flow down Swiftcurrent Creek to the St. Mary River, from which it is diverted to the Milk River, flowing through Canada for 216 miles (348 km) before returning to the United States. Use of these waters is governed by the Boundary Waters Treaty of 1909. Water from the Milk River is used for irrigation in north central Montana.
The San Juan–Chama Project is a U.S. Bureau of Reclamation interbasin water transfer project located in the states of New Mexico and Colorado in the United States. The project consists of a series of tunnels and diversions that take water from the drainage basin of the San Juan River – a tributary of the Colorado River – to supplement water resources in the Rio Grande watershed. The project furnishes water for irrigation and municipal water supply to cities along the Rio Grande including Albuquerque and Santa Fe.
The Spanish Fork is a river in southeastern Utah County, Utah, United States.
