List of tallest dams in the United States

Last updated

This is a list of the tallest dams in the United States . The main list includes all U.S. dams over 300 feet (91 m) tall, and a second list gives the tallest dams in each state. Dimensions given are for foundation height, not hydraulic height or head. Structures such as levees, dikes and tailings dams are not included in the lists. Decommissioned or failed dams, such as Teton Dam in Idaho, are included. Both lists are works in progress and will be updated periodically with new information. There are currently 75 entries on the main list.

Contents

Most of the U.S.'s taller dams are located in the west because of the steeper and more rugged topography. The tallest is Oroville Dam in northern California, a 770.5-foot (234.8 m) embankment dam completed in 1968. Five of the ten tallest dams in the U.S. are located in California. The Colorado, Columbia and SacramentoSan Joaquin river systems contain the greatest number of tall dams. In the eastern U.S., tall dams are less common because of the lesser vertical relief. The tallest dam in the eastern U.S. is 480-foot (150 m) Fontana Dam in North Carolina, which ranks 20th in height among all U.S. dams.

<span class="mw-page-title-main">Hoover Dam</span> Dam in Clark County, Nevada, and Mohave County, Arizona, US

Hoover Dam is a concrete arch-gravity dam in the Black Canyon of the Colorado River, on the border between the U.S. states of Nevada and Arizona. Constructed between 1931 and 1936, during the Great Depression, it was dedicated on September 30, 1935, by President Franklin D. Roosevelt. Its construction was the result of a massive effort involving thousands of workers, and cost over 100 lives. In bills passed by Congress during its construction, it was referred to as the Hoover Dam, after President Herbert Hoover, but was named the Boulder Dam by the Roosevelt administration. In 1947, the name Hoover Dam was restored by Congress.

<span class="mw-page-title-main">Colorado River</span> Major river in the western United States and Mexico

The Colorado River is one of the principal rivers in the Southwestern United States and in northern Mexico. The 1,450-mile-long (2,330 km) river, the 5th longest in the United States, drains an expansive, arid watershed that encompasses parts of seven U.S. states and two Mexican states. The name Colorado derives from the Spanish language for "colored reddish" due to its heavy silt load. Starting in the central Rocky Mountains of Colorado, it flows generally southwest across the Colorado Plateau and through the Grand Canyon before reaching Lake Mead on the Arizona–Nevada border, where it turns south toward the international border. After entering Mexico, the Colorado approaches the mostly dry Colorado River Delta at the tip of the Gulf of California between Baja California and Sonora.

<span class="mw-page-title-main">Glen Canyon Dam</span> Dam in Arizona, USA

Glen Canyon Dam is a concrete arch-gravity dam in the southwestern United States, located on the Colorado River in northern Arizona, near the city of Page. The 710-foot-high (220 m) dam was built by the Bureau of Reclamation (USBR) from 1956 to 1966 and forms Lake Powell, one of the largest man-made reservoirs in the U.S. with a capacity of more than 25 million acre-feet (31 km3). The dam is named for Glen Canyon, a series of deep sandstone gorges now flooded by the reservoir; Lake Powell is named for John Wesley Powell, who in 1869 led the first expedition to traverse the Colorado River's Grand Canyon by boat.

<span class="mw-page-title-main">Lake Mead</span> Reservoir on the Colorado River in Arizona and Nevada

Lake Mead is a reservoir formed by the Hoover Dam on the Colorado River in the Southwestern United States. It is located in the states of Nevada and Arizona, 24 mi (39 km) east of Las Vegas. It is the largest reservoir in the US in terms of water capacity. Lake Mead provides water to the states of Arizona, California, and Nevada as well as some of Mexico, providing sustenance to nearly 20 million people and large areas of farmland.

<span class="mw-page-title-main">United States Bureau of Reclamation</span> Government agency

The Bureau of Reclamation, formerly the United States Reclamation Service, is a federal agency under the U.S. Department of the Interior, which oversees water resource management, specifically as it applies to the oversight and operation of the diversion, delivery, and storage projects that it has built throughout the western United States for irrigation, water supply, and attendant hydroelectric power generation. It is currently the U.S.'s largest wholesaler of water, bringing water to more than 31 million people, and providing one in five Western farmers with irrigation water for 10 million acres of farmland, which produce 60% of the nation's vegetables and 25% of its fruits and nuts. The Bureau is also the second largest producer of hydroelectric power in the western U.S.

<span class="mw-page-title-main">Parker Dam</span> Colorado River dam between Arizona and California

Parker Dam is a concrete arch-gravity dam that crosses the Colorado River 155 miles (249 km) downstream of Hoover Dam. Built between 1934 and 1938 by the Bureau of Reclamation, it is 320 feet (98 m) high, 235 feet (72 m) of which are below the riverbed (the deep excavation was necessary in order to reach the bedrock on which the foundation of the dam was built), making it the deepest dam in the world. The portion of the dam above the foundation stands 85 feet (25.9 m) tall, making it the only dam in the world that stands more underground than above ground. The dam's primary functions are to create a reservoir, and to generate hydroelectric power. The reservoir behind the dam is called Lake Havasu and can store 647,000 acre⋅ft (798,000,000 m3; 2.11×1011 US gal; 1.76×1011 imp gal). The dam straddles the Arizona-California state border at the narrows the river passes through between the Whipple Mountains in San Bernardino County, California and the Buckskin Mountains in La Paz County, Arizona.

<span class="mw-page-title-main">Dworshak Dam</span> Dam in Idaho

Dworshak Dam is a concrete gravity dam in the western United States, on the North Fork of the Clearwater River in north central Idaho. In Clearwater County, the dam is located approximately four miles (6 km) northwest of Orofino and impounds the Dworshak Reservoir for flood control and hydroelectricity generation. By capacity, the reservoir is the largest in Idaho and fourth-largest in the Pacific Northwest.

<span class="mw-page-title-main">Trinity Dam</span> Dam in Trinity County, 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.

<span class="mw-page-title-main">Flaming Gorge Dam</span> Dam on the Green River in Utah, United States

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.

<span class="mw-page-title-main">Owyhee Dam</span> Dam in Malheur County, Oregon

Owyhee Dam is a concrete arch-gravity dam on the Owyhee River in Eastern Oregon near Adrian, Oregon, United States. Completed in 1932 during the Great Depression, the dam generates electricity and provides irrigation water for several irrigation districts in Oregon and neighboring Idaho. At the time of completion, it was the tallest dam of its type in the world. The dam is part of the Owyhee Dam Historic District, which is listed on the National Register of Historic Places.

<span class="mw-page-title-main">Risks to the Glen Canyon Dam</span> Aspect of dam construction

Glen Canyon Dam, a concrete arch dam on the Colorado River in the American state of Arizona, is viewed as carrying a large amount of risk, most notably due to siltation. The Colorado and San Juan rivers deposit large volumes of silt into Lake Powell, slowly decreasing its capacity. The sediment will eventually build up against the dam and could affect its safe operation and lead to its failure.

<span class="mw-page-title-main">Bridge Canyon Dam</span> Proposed dam in Mohave County, Arizona

Bridge Canyon Dam, also called Hualapai Dam, was a proposed dam in the lower Grand Canyon of the Colorado River, in northern Arizona in the United States. It would have been located near Bridge Canyon Rapids in an extremely rugged and isolated portion of the canyon, 235 miles (378 km) downstream of Lees Ferry and at the uppermost end of Lake Mead.

The Marble Canyon Dam, also known as the Redwall Dam, was a proposed dam on the Colorado River in Arizona, United States. The dam was intended to impound a relatively small reservoir in the central portion of Marble Canyon to develop hydroelectric power. Plans centered on two sites between miles 30 and 40 in the canyon. At one point a 38-mile (61 km) tunnel was proposed to a site just outside Grand Canyon National Park to develop the site's full power generation potential, reducing the Colorado River to a trickle through the park.
