Dartmouth Dam is a large rock-fill embankment dam with an uncontrolled chute spillway across the Mitta Mitta, Gibbo and Dart rivers, the Morass Creek and a number of small tributaries. The dam is located near Mount Bogong in the north-east of the Australian state of Victoria. The dam's purpose includes irrigation, the generation of hydro-electric power, water supply and conservation. The impounded reservoir is called Dartmouth Reservoir, sometimes called Lake Dartmouth. The Dartmouth Power Station, a hydro-electric power station that generates power to the national grid, is located near the dam wall.
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.
Warragamba Dam is a heritage-listed dam in the outer South Western Sydney suburb of Warragamba, Wollondilly Shire in New South Wales, Australia. It is a concrete gravity dam, which creates Lake Burragorang, the primary reservoir for water supply for the city of Sydney. The dam wall is located approximately 65 kilometres (40 mi) W of Sydney central business district, 4½ km SW of the town of Wallacia, and 1 km NW of the village of Warragamba.
Lake Burragorang is a man-made reservoir in the lower Blue Mountains of New South Wales, Australia, serving as a major water supply for greater metropolitan Sydney. The dam impounding the lake, the Warragamba Dam, is located approximately 60 kilometres (37 mi) southwest of the Sydney central business district.
A spillway is a structure used to provide the controlled release of water downstream from a dam or levee, typically into the riverbed of the dammed river itself. In the United Kingdom, they may be known as overflow channels. Spillways ensure that water does not damage parts of the structure not designed to convey water.
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).
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.
Copeton Dam is a major clay core and rock fill embankment dam with nine radial gates and a gated concrete chute spillway across the Gwydir River upstream of Bingara in the New England region of New South Wales, Australia. The dam's purpose includes environmental flows, hydro-electric power generation, irrigation, and water supply. The impounded reservoir is called Lake Copeton.
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 takes it names from the local Wivenhoe Pocket rural community. 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.
The Ross River Dam is a rock and earthfill-filled embankment dam across the Ross River, located between Kelso and Mount Stuart in the City of Townsville in northern Queensland, Australia. Built initially for flood control, Lake Ross, the impoundment created by the dam, serves as one of the major potable water supplies for the region.
The Nillahcootie Dam, a rock and earth-fill embankment dam with a unique Gothic arch-shaped crest spillway across the Broken River that is located near Mansfield, in the Alpine region of Victoria, Australia. The dam's purpose is for the supply of potable water and for irrigation. The impounded reservoir is called Lake Nillahcootie.
The Sayano-Shushenskaya Dam is located on the Yenisei River, near Sayanogorsk in Khakassia, Russia. It is the largest power plant in Russia and the 12th-largest hydroelectric plant in the world, by average power generation. The full legal name of the power plant, OJSC [Open Joint-Stock Society] P. S. Neporozhny Sayano-Shushenskaya HPP [hydro power plant], refers to the Soviet-time Minister of Energy and Electrification Pyotr Neporozhny. As of 2009 the head of the power plant was Valery Kyari.
The Fairbairn Dam is an earth-filled embankment dam across the Nogoa River, located southwest of Emerald in Central Queensland, Australia. Constructed in 1972 for the primary purpose of irrigation, the impoundment created by the dam serves as one of the major potable water supplies for the region and assists with some flood mitigation.
The Warragamba River, a river that is part of the Hawkesbury-Nepean catchment, is located in the Macarthur region of New South Wales, Australia.
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.
Ben Chifley Dam, or Chifley Dam, is a rock and earth-fill embankment dam across the Campbells River in the central west region of New South Wales, Australia. The main purpose of the dam is to supply potable water to the city of Bathurst.
Oberon Dam or Fish River Dam is a major ungated concrete slab and buttress with earth embankment dam comprising a concrete ski jump chute spillway and fuse plug across the Fish River upstream of Oberon in the Central Tablelands region of New South Wales, Australia. The dam's purpose includes flood mitigation, industrial, and water supply. The impounded reservoir is called Lake Oberon.
Warragamba Dam – Haviland Park is a heritage-listed former farm, dam, timber getting, Gundungurra traditional lands and squatter's land and now parkland located at Warragamba Dam in the south-western Sydney settlement of Warragamba in the Wollondilly Shire local government area of New South Wales, Australia.

Extreme rainfall on the east coast of Australia beginning on 18 March 2021 led to widespread flooding in New South Wales, affecting regions from the North Coast to the Sydney metropolitan area in the south. Suburbs of Sydney experienced the worst flooding in 60 years, and the events were described by NSW Premier Gladys Berejiklian as "one in 100-year" flooding. Far-southeast communities in Queensland were also affected by flooding and heavy rainfall, though to a lesser extent than those in New South Wales.
