The Gatun Dam is a large earthen dam across the Chagres River in Panama, near the town of Gatun. The dam, constructed between 1907 and 1913, is a crucial element of the Panama Canal; it impounds the artificial Gatun Lake, which in turn carries ships 33 kilometres (21 mi) of their transit across the Isthmus of Panama. In addition, a hydro-electric generating station at the dam generates electricity which is used to operate the locks and other equipment in the canal.
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.
The Robert-Bourassa generating station, formerly known as La Grande-2 (LG-2), is a hydroelectric power station on the La Grande River that is part of Hydro-Québec's James Bay Project in Canada.

The ponmudi dam is a concrete gravity dam built across the Panniyar river which is a tributary of Periyar River at Konnathadi panchayath of Konnathadi village in Idukki district of Kerala, India. The dam was constructed in 1963 as a part of a hydroelectric project. It has a length of 294 metres (965 ft) and a length of 288.80 metres (947.5 ft). The hydropower component of the dam has an installed capacity of 30 MW with firm power of 17 MW, generating 158 GWh annually. Taluks through which the river flow are Udumpanchola, Devikulam, Kothamangalam, Muvattupuzha, Kunnathunadu, Aluva, Kodungalloor and Paravur.
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.
Feicui Dam is a double curvature concrete arch dam on the Beishi River in Shiding District, New Taipei, Taiwan, forming Feicui Reservoir (翡翠水庫). The dam is located in Shiding District, New Taipei City, and is usually misunderstood as the principal water source for the Greater Taipei area. The name of the dam and reservoir translates as "emerald lake", in reference to the pure quality of the water. The area is managed by the Taipei Feicui Reservoir Administration. Public access is heavily restricted in order to protect water quality, which is among the highest of Taiwan's reservoirs.
Deriner Dam is a concrete double-curved arch dam on the Çoruh River 5 km (3.1 mi) east of Artvin in Artvin Province, Turkey. The main purpose of the dam is hydroelectric power production and additionally flood control. Construction on the dam began in 1998, the reservoir began to fill in February 2012 and the power station was completed by February 2013. It will have a 670 MW power house and is the tallest dam in Turkey. The dam is being implemented by Turkey's State Hydraulic Works and constructed by a consortium of Turkish, Russian and Swiss companies.
Richard B. Russell Dam is a concrete-gravity and embankment dam located on the Savannah River at the border of South Carolina and Georgia, creating Richard B. Russell Lake. The dam was built by the U.S. Army Corps of Engineers between 1974 and 1985 for the purposes of flood control, hydroelectricity, recreation, additional stream flow regulation, water supply, and fish and wildlife management. The concrete structure of the dam spans 1,904 feet (580 m) and rises 210 feet (64 m) above the riverbed, housing a hydro-power plant with an installed 600 megawatts (800,000 hp) capacity. The Richard B. Russell Dam is the final large dam completed by the U.S. Army Corps in the Savannah River Basin and lies 30 miles downstream from the Hartwell Dam (1962) and 37 miles (60 km) upstream from the J. Strom Thurmond Dam (1954).
