1. Dams History:

Early dam building took place in Mesopotamia and the Middle East. Dams were used to control the water level, for Mesopotamia's weather affected the Tigris and Euphrates rivers. The earliest known dam is the Jawa Dam in Jordan, 100 kilometres (62 mi) northeast of the capital Amman. This gravity dam featured an originally 9-metre-high (30 ft) and 1 m-wide (3.3 ft) stone wall, supported by a 50 m-wide (160 ft) earth rampart. The structure is dated to 3000 BC. More details

2. Grand Coulee Dam:

Grand Coulee Dam is a concrete gravity dam on the Columbia River in the U.S. state of Washington, built to produce hydroelectric power and provide irrigation water. Constructed between 1933 and 1942, Grand Coulee originally had only two powerhouses. The third powerhouse, completed in 1974 to increase energy production, makes Grand Coulee the largest power station in the United States by nameplate-capacity at 6,809 MW. However, in terms of yearly power production, Grand Coulee places fifth after a number of nuclear facilities to the south, like Palo Verde west of Phoenix. This is because river flow varies throughout the year. More details

3. Itaipu Dam:

The Itaipu Dam is a hydroelectric dam on the Paraná River located on the border between Brazil and Paraguay. The construction of the dam was first contested by Argentina, but the negotiations and resolution of the dispute ended up setting the basis for Argentine–Brazilian integration later on. The name "Itaipu" was taken from an isle that existed near the construction site. In the Guarani language, Itaipu means "the sounding stone". The Itaipu Dam's hydroelectric power plant produced the most energy of any in the world as of 2016, setting a new world record of 103,098,366 megawatt hours (MWh), and surpassed the Three Gorges Dam plant in energy production in 2015 and 2016. More details

4. Oroville Dam:

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 man-made lake in the state of California, capable of storing more than 3.5 million acre-feet (4.4 km3). Built by the California Department of Water Resources (DWR), Oroville Dam is one of the key features of the California State Water Project (SWP), one of two major projects passed that set up California's statewide water system. More details

5. Three Gorges Dam:

The Three Gorges Dam is a hydroelectric gravity dam that spans the Yangtze River by the town of Sandouping, in Yiling District, Yichang, Hubei province, China. The Three Gorges Dam is the world's largest power station in terms of installed capacity (22,500 MW). In 2014 the dam generated 98.8 terawatt-hours (TWh) and had the world record, but was surpassed by the Itaipú Dam, which set the new world record in 2016, producing 103.1 TWh. More details

6. Tarbela Dam:

Tarbela Dam is an earth fill dam on the Indus River in Khyber Pakhtunkhwa in Pakistan. It's the largest earth-filled dam in the world and also the largest by structural volume. It is named after the town Tarbela, in Khyber Pakhtunkhwa, about 50 kilometres (31 mi) northwest of Islamabad, at Haripur District. The main dam wall, built of earth and rock fill, stretches 2,743 metres (8,999 ft) from the island to river right, standing 148 metres (486 ft) high. A pair of concrete auxiliary dams spans the river from the island to river left. More details

7. Aswan High Dam:

The Aswan High Dam is an embankment dam 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 control flooding better, 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. More details

8. Glen Canyon Dam:

Glen Canyon Dam is a concrete arch-gravity dam on the Colorado River in northern Arizona, United States, near the town of Page. The 710-foot (220 m) high dam was built by the U.S. 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 27 million acre feet (33 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's Grand Canyon by boat. More details

9. Gavins Point Dam:

Gavins Point Dam is a large embankment rolled-earth and chalk-fill dam on the Missouri River located in both Nebraska and South Dakota in the Upper Midwest Region of the United States. The dam and hydroelectric power plant were constructed as the Gavins Point Project from 1952 to 1957 by the United States Army Corps of Engineers. The dam creates the 31,400 acre (12,700 ha) Lewis and Clark Lake and is located approximately 4 miles west (6.4 km) (upstream) of Yankton, South Dakota. More details

10. Afsluitdijk Dam:

The Afsluitdijk is a major causeway in the Netherlands, constructed between 1927 and 1932 and running from Den Oever on Wieringen in North Holland province, to the village of Zurich in Friesland province, over a length of 32 kilometres (20 mi) and a width of 90 metres (300 ft), at an initial height of 7.25 metres (23.8 ft) above sea level. It is a fundamental part of the larger Zuiderzee Works, damming off the Zuiderzee, a salt water inlet of the North Sea, and turning it into the fresh water lake of the IJsselmeer. The Afsluitdijk was the initial demonstration site for a 130 km/h (81 mph) speed limit in the Netherlands. More details

11. Zhiguli Dam:

The Zhiguli Hydroelectric Station or Zhigulyovskaya Hydroelectric Station, formerly known as Kuybyshev Hydroelectric Station (Kuybyshev GES) is a large dam and hydroelectric station on the Volga River, located near Zhigulyovsk and Tolyatti in Samara Oblast of Russia. It is the sixth stage of the Volga-Kama Cascade of dams, and the second of them by installed power. Construction started in 1950 and was completed in 1957. The complex consists of earth-fill dam, 2800 m long, 750 m wide and 52 m high, concrete spillway dam, 980 m long, power plant house, 700 m long, and two-lane navigable locks. More details

12. Shannon Dam:

The Shannon hydroelectric Scheme was a major development by the Irish Free State in the 1920s to harness the power of the River Shannon. Its product, the Ardnacrusha power plant, is a hydroelectric power station which is still producing power today and is located near Ardnacrusha within County Clare approximately 2.4 kilometres (1.5 mi) from the Limerick border. It is Ireland's largest river hydroelectric scheme and is operated on a purpose built headrace connected to the River Shannon. The plant includes fish ladders so that returning fish, such as salmon, can climb the river safely past the power station. More details

13. Taum Sauk Upper Reservoir:

The Taum Sauk pumped storage plant is in the St. Francois mountain region of the Missouri Ozarks about 90 miles (140 km) south of St. Louis near Lesterville, Missouri, in Reynolds County. It is operated by Ameren Missouri (previously AmerenUE, formerly Union Electric). The pumped-storage hydroelectric plant was constructed from 1960-1962 and was designed to help meet daytime peak electric power demand. It began operation in 1963. Electrical generators are turned by water flowing from a reservoir on top of Proffit Mountain into a lower reservoir on the East Fork of the Black River. At night, excess electricity on the power grid is used to pump water back to the mountaintop. More details

14. Fort Peck Dam:

The Fort Peck Dam is the highest of six major dams along the Missouri River, located in northeast Montana in the United States, near Glasgow, and adjacent to the community of Fort Peck. At 21,026 feet (6,409 m) in length and over 250 feet (76 m) in height, it is the largest hydraulically filled dam in the United States, and creates Fort Peck Lake, the fifth largest man-made lake in the U.S., more than 130 miles (210 km) long, 200 feet (61 m) deep, and it has a 1,520-mile (2,450 km) shoreline which is longer than the state of California's coastline. It lies within the Charles M. Russell National Wildlife Refuge. The dam and the 134-mile-long (216 km) lake are owned and operated by the U.S. Army Corps of Engineers and exist for the purposes of hydroelectric power generation, flood control, and water quality management. More details

15. Hoover Dam:

Hoover Dam, once known as Boulder Dam, is a concrete arch-gravity dam in the Black Canyon of the Colorado River, on the border between the U.S. states of Arizona and Nevada. The Dam 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. The dam was controversially named after President Herbert Hoover. More details

16. Atatürk Dam:

The Atatürk Dam (Atatürk Barajı), originally the Karababa Dam, is a zoned rock-fill dam with a central core on the Euphrates River on the border of Adıyaman Province and Şanlıurfa Province in the Southeastern Anatolia Region of Turkey. Built both to generate electricity and to irrigate the plains in the region, it was renamed in honour of Mustafa Kemal Atatürk (1881–1938), the founder of the Turkish Republic. The construction began in 1983 and was completed in 1990. The dam and the hydroelectric power plant, which went into service after the upfilling of the reservoir was completed in 1992, are operated by the State Hydraulic Works (DSİ). More details

17. Arrowrock Dam:

Arrowrock Dam is a concrete arch dam on the Boise River, in the U.S. state of Idaho. It opened in 1915 and is located on the border between Boise County and Elmore County, upstream of the Lucky Peak Dam and reservoir. The spillway elevation for Arrowrock is 3,219 feet (981 m) above sea level and its primary purpose is to provide irrigation water for agriculture. In 1910, the Reclamation Service began to consider another storage facility farther east on the Boise River. After several surveys, engineers decided upon the Arrowrock site which had previously been the site of a private irrigation venture under the direction of Arthur De Wint Foote yet failed for lack of funding. More details

18. Kensico Dam:

The Kensico Reservoir is a reservoir located in the towns of Armonk (North Castle) and Valhalla (Mount Pleasant), New York. It was formed by the old earth and gravel dam, built in 1885, which impounded waters from the Bronx and Byram rivers, and supplied about 18 million gallons daily. The construction of a new masonry dam in 1915, replaced the old dam, and expanded the water supply by bringing water from the Catskill Mountains over a distance of more than 100 miles. It is about 3 miles (5 km) north of downtown White Plains, New York, and about 15 miles (24 km) north of New York City. The reservoir serves mainly to store the waters received from the Catskill Mountains west of the Hudson River. More details

19. Marmot Dam:

The Bull Run Hydroelectric Project was a Portland General Electric (PGE) development in the Sandy River basin in the U.S. state of Oregon. Originally built between 1908 and 1912 near the town of Bull Run, it supplied hydroelectric power for the Portland area for nearly a century, until it was removed in 2007 and 2008. The project used a system of canals, tunnels, wood box flumes and diversion dams to feed a remote storage reservoir and powerhouse. The entire project was removed because of rising environmental costs. Marmot Dam on the Sandy River was demolished in 2007, and the Little Sandy Dam on the Little Sandy River was taken down in 2008. More details

20. Condit Dam:

Condit Hydroelectric Project was a development on the White Salmon River in the U.S. state of Washington. It was completed in 1913 to provide electrical power for local industry and is listed in the National Register of Historic Places as an engineering and architecture landmark. PacifiCorp decommissioned the project due to rising environmental costs, and the dam was intentionally breached on October 26, 2011. Condit Dam was the largest dam ever removed in the United States until the Elwha Ecosystem Restoration Project on the Olympic Peninsula removed the larger Elwha Dam and Glines Canyon Dams. The White Salmon is a glacier-fed river originating on the slopes of Mount Adams and emptying into the Columbia River. More details
