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. Originally known as Boulder Dam from 1933, it was officially renamed Hoover Dam for President Herbert Hoover by a joint resolution of Congress in 1947.
A dam is a barrier that stops or restricts the flow of 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 water or for storage of 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. The earliest known dam is the Jawa Dam in Jordan, dating to 3,000 BC.
Young is a town in the South West Slopes region of New South Wales, Australia and the largest town in the Hilltops Region. The "Lambing Flat" Post Office opened on 1 March 1861 and was renamed "Young" in 1863.
Bonneville Lock and Dam consists of several run-of-the-river dam structures that together complete a span of the Columbia River between the U.S. states of Oregon and Washington at River Mile 146.1. The dam is located 40 miles (64 km) east of Portland, Oregon, in the Columbia River Gorge. The primary functions of Bonneville Lock and Dam are electrical power generation and river navigation. The dam was built and is managed by the United States Army Corps of Engineers. At the time of its construction in the 1930s it was the largest water impoundment project of its type in the nation, able to withstand flooding on an unprecedented scale. Electrical power generated at Bonneville is distributed by the Bonneville Power Administration. Bonneville Lock and Dam is named for Army Capt. Benjamin Bonneville, an early explorer credited with charting much of the Oregon Trail. The Bonneville Dam Historic District was designated a National Historic Landmark District in 1987.
The St. Francis Dam was a curved concrete gravity dam, built to create a large regulating and storage reservoir for the city of Los Angeles, California. The reservoir was an integral part of the city's Los Angeles Aqueduct water supply infrastructure. It was located in San Francisquito Canyon of the Sierra Pelona Mountains, about 40 miles (64 km) northwest of downtown Los Angeles, and approximately 10 miles (16 km) north of the present day city of Santa Clarita.
Dam Square or Dam is a town square in Amsterdam, the capital of the Netherlands. Its notable buildings and frequent events make it one of the most well-known and important locations in the city and the country.
An arch dam is a concrete dam that is curved upstream in plan. The arch dam is designed so that the force of the water against it, known as hydrostatic pressure, presses against the arch, causing the arch to straighten slightly and strengthening the structure as it pushes into its foundation or abutments. An arch dam is most suitable for narrow canyons or gorges with steep walls of stable rock to support the structure and stresses. Since they are thinner than any other dam type, they require much less construction material, making them economical and practical in remote areas.
The Farmington River is a river, 46.7 miles (75.2 km) in length along its main stem, which is located in northwest Connecticut with major tributaries extending into southwest Massachusetts. Via its longest branch, the Farmington's length increases to 80.4 miles (129.4 km), making it the Connecticut River's longest tributary by a mere 2.3 miles (3.7 km) over the major river directly to its north, the Westfield River. The Farmington River's watershed covers 609 square miles (1,580 km2). Historically, the river played an important role in small-scale manufacturing in towns along its course, but it is now mainly used for recreation and drinking water.
The Marib Dam is a modern dam blocking the Wadi Adhanah in the valley of Dhana in the Balaq Hills, located in the Ma'rib Governorate in Yemen. The current dam was built in the 1980s and is close to the ruins of the ancient Great Dam of Ma'rib, first built in the 8th century BC. It was one of the engineering wonders of the ancient world and a central part of the Sabaean and Himyarite kingdoms around Ma'rib.
Burrendong Dam is a rock-fill embankment major gated dam with a clay core across the Macquarie River upstream of Wellington in the central west region of New South Wales, Australia. The dam's purpose includes flood mitigation, irrigation, water supply and hydro-electric power generation. The dam impounds Lake Burrendong and is filled by the waters from the Macquarie, and Cudgegong rivers as well as Meroo Creek.
The Keban Dam is a hydroelectric dam on the Euphrates, located in the Elazığ Province of Turkey. The dam was the first and uppermost of several large-scale dams to be built on the Euphrates by Turkey. Although the Keban Dam was not originally constructed as a part of the Southeastern Anatolia Project (GAP), it is now a fully integrated component of the project, which aims to stimulate economic development in Southeastern Turkey. Construction of the dam commenced in 1966 and was completed in 1974. Keban Dam Lake, the reservoir created by Keban Dam, has a surface area of 675 square kilometres (261 sq mi) and is reputedly the fourth-largest lake in Turkey after Lake Van, Lake Tuz, and the reservoir created by the Atatürk Dam.
The Somerset Dam is a mass concrete gravity dam with a gated spillway across the Stanley River in Queensland, Australia. It is within the locality of Somerset Dam in the Somerset Region in South East Queensland. The main purpose of the dam is the supply of potable water for the Brisbane, Gold Coast and Logan City regions. Additionally, the dam provides for flood mitigation, recreation and for the generation of hydroelectricity. The impounded reservoir is called Lake Somerset.
Cantref Reservoir is the middle of the three reservoirs in the Taff Fawr valley in Wales. It was built by Cardiff Corporation Waterworks between 1886 and 1892, but since 1973 has been owned by Welsh Water. It is located in the Brecon Beacons National Park, mostly in the Powys unitary authority area and within the historic county boundaries of Breconshire. Part of the south west corner is in the Rhondda Cynon Taff unitary authority area.
Lock and Dam No. 19 is a lock and dam located on the Upper Mississippi River near Keokuk, Iowa. In 2004, the facility was listed in the National Register of Historic Places as Lock and Dam No. 19 Historic District, #04000179 covering 1,605 acres (650 ha), 7 buildings, 12 structures, 1 object. The lock is owned and operated by the U.S. Army Corps of Engineers. The dam is owned and operated by Ameren Missouri.
Parker Dam State Park is a 968-acre (392 ha) Pennsylvania state park in Huston Township, Clearfield County, Pennsylvania in the United States. The park is surrounded by Moshannon State Forest. Parker Dam State park is 17 miles (27 km) north of Clearfield on Pennsylvania Route 153 just off exit 111 of Interstate 80. The park was constructed during the Great Depression by the Civilian Conservation Corps. They built many of the facilities that are in use today at Parker Dam State Park.
Town Brook is a 1.5-mile (2.4 km) stream in Plymouth, Massachusetts that provided drinking water to the Pilgrims who made their homes adjacent to the brook on Leyden Street in Plymouth. Town Brook's headwaters are the Billington Sea, a 269-acre (109 ha) freshwater pond. The brook passes through numerous small ponds, including Deep Water Pond and Jenny Pond. It also passes by the Plimoth Grist Mill and the Brewster Gardens before emptying into Plymouth Harbor. A nature trail runs along the entire length of the brook.

Buffalo Bill Dam is a concrete arch-gravity dam on the Shoshone River in the U.S. state of Wyoming. It is named after the famous Wild West figure William "Buffalo Bill" Cody, who founded the nearby town of Cody and owned much of the land now covered by the reservoir formed by its construction. The dam is part of the Shoshone Project, successor to several visionary schemes promoted by Cody to irrigate the Bighorn Basin and turn it from a semi-arid sagebrush-covered plain to productive agricultural land. Known at the time of its construction as Shoshone Dam, it was renamed in 1946 to honor Cody.
