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 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.
Northville is a village in Fulton County, New York. The population was 1,099 at the 2010 census. The village is in the northern part of the town of Northampton and is northeast of Gloversville.
The Mohawk River is a 149-mile-long (240 km) river in the U.S. state of New York. It is the largest tributary of the Hudson River. The Mohawk flows into the Hudson in Cohoes, New York, a few miles north of the city of Albany. The river is named for the Mohawk Nation of the Iroquois Confederacy. It is a major waterway in north-central New York.
A spillway is a structure used to provide the controlled release of flows from a dam or levee into a downstream area, typically the riverbed of the dammed river itself. In the United Kingdom, they may be known as overflow channels. Spillways ensure that the water does not overflow and damage or destroy the dam.
The Great Sacandaga Lake is a large lake situated in the Adirondack Park in northern New York in the United States. The lake has a surface area of about 41.7 square miles (108 km2) at capacity, and the length is about 29 miles (47 km). The word Sacandaga means "Land of the Waving Grass" in the local native language. The lake is located in the northern parts of Fulton County and Saratoga County near the south border of the Adirondack Park. A small part of it also extends northward into southern Hamilton County. The broader, south end of the lake is northeast of the City of Johnstown and the City of Gloversville. Great Sacandaga Lake is a reservoir created by damming the Sacandaga River. The primary purpose for the creation of the reservoir was to control flooding on the Hudson River and the Sacandaga River, floods which had a historically significant impact on the surrounding communities.
Table Rock Lake is an artificial lake or reservoir in the Ozarks of southwestern Missouri and northwestern Arkansas. The lake is impounded by Table Rock Dam constructed from 1954 to 1958 on the White River by the U.S. Army Corps of Engineers.
Dworshak Dam is a concrete gravity dam in the western United States, on the North Fork Clearwater River in Clearwater County, Idaho. The dam is located approximately four miles (6 km) northwest of Orofino and impounds the Dworshak Reservoir for flood control and hydroelectricity generation. With a height of 717 feet (219 m), Dworshak is the third tallest dam in the United States and the tallest straight-axis concrete dam in the Western Hemisphere. Construction of the dam by the U.S. Army Corps of Engineers (USACE) began in 1966 and was completed in 1973.
The American Falls Dam is a concrete gravity-type dam located near the town of American Falls, Idaho, on river mile 714.7 of the Snake River. The dam and reservoir are a part of the Minidoka Project on the Snake River Plain and are used primarily for flood control, irrigation, and recreation. When the original dam was built by the Bureau of Reclamation, the residents of American Falls were forced to relocate three-quarters of their town to make room for the reservoir. A second dam was completed in 1978 and the original structure was demolished. Although the dam itself is located in Power County, its reservoir also stretches northeastward into both Bingham County and Bannock County.
A reservoir is, most commonly, an enlarged natural or artificial lake, pond or impoundment created using a dam or lock to store water.
The Haditha Dam or Qadisiya Dam is an earth-fill dam on the Euphrates, north of Haditha (Iraq), creating Lake Qadisiyah. The dam is just over 9 kilometres (5.6 mi) long and 57 metres (187 ft) high. The purpose of the dam is to generate hydroelectricity, regulate the flow of the Euphrates and provide water for irrigation. It is the second-largest hydroelectric contributor to the power system in Iraq behind the Mosul Dam.
Douglas Dam is a hydroelectric dam on the French Broad River in Sevier County, Tennessee, in the southeastern United States. The dam is operated by the Tennessee Valley Authority (TVA), which built the dam in record time in the early 1940s to meet emergency energy demands at the height of World War II. Douglas Dam is a straight reinforced concrete gravity-type dam 1705 feet long and 202 feet high, impounding the 28,420-acre (11,500 ha) Douglas Lake. The dam was named for Douglas Bluff, a cliff overlooking the dam site prior to construction.
Run-of-river hydroelectricity (ROR) or run-of-the-river hydroelectricity is a type of hydroelectric generation plant whereby little or no water storage is provided. Run-of-the-river power plants may have no water storage at all or a limited amount of storage, in which case the storage reservoir is referred to as pondage. A plant without pondage is subject to seasonal river flows, thus the plant will operate as an intermittent energy source. Conventional hydro uses reservoirs, which regulate water for flood control and dispatchable electrical power.
The Longyangxia Dam is a concrete arch-gravity dam at the entrance of the Longyangxia canyon on the Yellow River in Gonghe County, Qinghai Province, China. The dam is 178 metres (584 ft) tall and was built for the purposes of hydroelectric power generation, irrigation, ice control and flood control. The dam supports a 1,280 MW power station with 4 x 320 MW generators that can operate at a maximum capacity of 1400 MW. Controlling ice, the dam controls downstream releases to reservoirs lower in the river, allowing them to generate more power instead of mitigating ice. Water in the dam's 24.7 billion m3 reservoir provides irrigation water for up to 1,000,000 hectares of land.
The Grand Ethiopian Renaissance Dam, formerly known as the Millennium Dam and sometimes referred to as Hidase Dam, is a gravity dam on the Blue Nile River in Ethiopia that has been under construction since 2011. It is in the Benishangul-Gumuz Region of Ethiopia, about 15 km (9 mi) east of the border with Sudan. At 6.45 gigawatts, the dam will be the largest hydroelectric power plant in Africa when completed, as well as the 7th largest in the world. As of August 2017, the work stood at 60% completion. Once completed, the reservoir will take from 5 to 15 years to fill with water.
Hiyoshi Dam (日吉ダム) is a dam in Nantan, Kyoto Prefecture, Japan. The dam construction started in 1992 and was completed in 1996.
The Hudson River-Black River Regulating District (HRBRRD) is a New York state public-benefit corporation that was established in 1922 in response to the severe historical flooding of the cities of Albany, Green Island, Rensselaer, Troy, and Watervliet by the Sacandaga River and Hudson River and its tributaries. The HRBRRD was created to collect excess runoff to prevent flooding in the Hudson River and Black River basins, and to release this captured water gradually during periods of low river flow to maintain water quality in each river basin. This system was designed to reduce damage from spring storms and snowmelt, including disease and destruction of life and property, and to improve river navigation and public sanitation. The HRBRRD was also formed with hydroelectric generation in mind. It owns and operates several dams - including the Conklingville Dam which formed the Great Sacandaga Lake - and reservoirs.
