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. It was constructed between 1931 and 1936 during the Great Depression and 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 one hundred lives. It was referred to as the Hoover Dam after President Herbert Hoover in bills passed by Congress during its construction; it was named the Boulder Dam by the Roosevelt administration. The Hoover Dam name was restored by Congress in 1947.
A dam is a barrier that stops or restricts the flow of surface water or underground streams. Reservoirs created by dams not only suppress floods but also provide water for activities such as irrigation, human consumption, industrial use, aquaculture, and navigability. Hydropower is often used in conjunction with dams to generate electricity. A dam can also be used to collect or store water which can be evenly distributed between locations. Dams generally serve the primary purpose of retaining water, while other structures such as floodgates or levees are used to manage or prevent water flow into specific land regions.
Lake Travis is a reservoir on the Colorado River in central Texas in the United States.
The Aswan Dam, or more specifically since the 1980s, the Aswan High Dam, is one of the world's largest embankment dams, which was built across the Nile in Aswan, Egypt, between 1960 and 1970. Its significance largely eclipsed the previous Aswan Low Dam initially completed in 1902 downstream. Based on the success of the Low Dam, then at its maximum utilization, construction of the High Dam became a key objective of the government following the Egyptian Revolution of 1952; with its ability to better control flooding, provide increased water storage for irrigation and generate hydroelectricity, the dam was seen as pivotal to Egypt's planned industrialization. Like the earlier implementation, the High Dam has had a significant effect on the economy and culture of Egypt.
Pyramid Dam is a dam on Piru Creek located in northern Los Angeles County, north of Castaic and south of Gorman. Its reservoir, Pyramid Lake, stores water from the West Branch California Aqueduct for Ventura County and Los Angeles County. They are smaller than Castaic Dam and Lake, the other artificial water storage facility in the area, 7 miles (11 km) to the south.
Oroville Dam is an earthfill embankment dam on the Feather River east of the city of Oroville, California, in the Sierra Nevada foothills east of the Sacramento Valley. At 770 feet (235 m) high, it is the tallest dam in the U.S. and serves mainly for water supply, hydroelectricity generation, and flood control. The dam impounds Lake Oroville, the second-largest reservoir in California, capable of storing more than 3.5 million acre-feet (1.1×10^12 US gal; 4.3×109 m3).
Wyangala Dam is a major gated rock fill with clay core embankment and gravity dam with eight radial gates and a concrete chute spillway across the Lachlan River, located in the south-western slopes region of New South Wales, Australia. The dam's purpose includes flood mitigation, hydro-power, irrigation, water supply and conservation. The impounded reservoir is called Lake Wyangala.
The Tennessee–Tombigbee Waterway is a 234-mile (377 km) artificial U.S. waterway built in the 20th century from the Tennessee River to the junction of the Black Warrior-Tombigbee River system near Demopolis, Alabama. The Tennessee–Tombigbee Waterway links commercial navigation from the nation's midsection to the Gulf of Mexico. The major features of the waterway are 234 miles (377 km) of navigation channels, a 175-foot-deep (53 m) cut between the watersheds of the Tombigbee and Tennessee rivers, and ten locks and dams. The locks are 9 by 110 by 600 feet, the same dimension as those on the Mississippi above Lock and Dam 26 at Alton, Illinois. Under construction for 12 years by the U.S. Army Corps of Engineers, the Tennessee–Tombigbee Waterway was completed in December 1984 at a total cost of nearly $2 billion.
Lake Parramatta is a heritage-listed man-made reservoir and a recreational area located in North Parramatta, City of Parramatta, in the Western Sydney region of New South Wales, Australia. The masonry arch-walled dam across Hunts Creek was completed in 1856 to supply water for domestic purposes; and was operational until 1909. The dam has since been decommissioned and the lake and the surrounding nature reserve are a popular recreational area.
Center Hill Lake is a reservoir in the U.S. state of Tennessee. It is located in Middle Tennessee near Smithville. Created by means of a dam constructed by the U.S. Army Corps of Engineers in 1948, the lake has a dual purpose: electricity production and flood control. Center Hill Dam is 260 ft (79 m) high, and it is composed of concrete and earth structures, with 8 gates that are 50 ft (15 m) wide each. Center Hill Lake is one of four major flood control reservoirs for the Cumberland; the others being Percy Priest Lake, Dale Hollow Reservoir, and Lake Cumberland.
Norfork Dam is a large dam in northern Arkansas southeast of Mountain Home. It dams North Fork River and creates Norfork Lake. The top of the dam supports a 2-lane roadway, part of AR 177.
The Wivenhoe Dam is a rock and earth-fill embankment dam with a concrete spillway across the Brisbane River in South East Queensland, Australia. The dam wall is located about 80 kilometres (50 mi) by road from the centre of Brisbane. The primary purpose of the dam is the supply of potable water for the Brisbane and Ipswich regions. The dam also provides for flood mitigation control, hydroelectricity, and recreation. The impounded reservoir is called Lake Wivenhoe and the dam, the lake and a narrow strip of surrounding land forms a locality also called Lake Wivenhoe.
Isabella Dam is an embankment dam located in the Kern River Valley, about halfway down the Kern River course, between the towns of Kernville and Lake Isabella in Kern County, California.
Lake Wyola is a lake located in Shutesbury, Massachusetts, United States.
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.
Lake Arrowhead is an artificial lake located in the San Bernardino Mountains on Little Bear Creek, a tributary of Deep Creek and the Mojave River. It has a surface area of approximately 780 acres (320 ha) and a capacity of 48,000 acre⋅ft (59,000 dam3). It is surrounded by the unincorporated community of Lake Arrowhead in San Bernardino County, California.
