Lake Sevan is the largest body of water in both Armenia and the Caucasus region. It is one of the largest freshwater high-altitude (alpine) lakes in Eurasia. The lake is situated in Gegharkunik Province, at an altitude of 1,900 m (6,234 ft) above sea level. The total surface area of its basin is about 5,000 km2 (1,900 sq mi), which makes up 1⁄6 of Armenia's territory. The lake itself is 1,242 km2 (480 sq mi), and the volume is 32.8 km3 (7.9 cu mi). It is fed by 28 rivers and streams. Only 10% of the incoming water is drained by the Hrazdan River, while the remaining 90% evaporates.
The Vaal Dam in South Africa was constructed in 1938 and lies 77 km south of OR Tambo International Airport, Johannesburg. The lake behind the dam wall has a surface area of about 320 square kilometres (120 sq mi) and is 47 meters deep. The Vaal Dam lies on the Vaal River, which is one of South Africa's strongest-flowing rivers. Other rivers flowing into the dam are the Wilge River, Molspruit and Grootspruit. It has over 800 kilometres (500 mi) of shoreline and is South Africa's second biggest dam by area and the fourth largest by volume.
The Hrazdan is a major river and the second largest in Armenia. It originates at the northwest extremity of Lake Sevan and flows south through the Kotayk Province and Armenia's capital, Yerevan; the lake in turn is fed by several streams. In the Ararat plain it joins the Aras river along the border with Turkey. Its waters join the Kura river, before flowing into the Caspian Sea.

Chichester Dam is a minor concrete gravity dam across the Chichester and Wangat rivers, upstream of Dungog, in the Hunter Region of New South Wales, Australia. The dam's main purpose is water supply for the Lower Hunter region. A mini hydro-electric power station operates at times of peak flow and is connected to the national grid. The impounded reservoir is Lake Chichester.
The Koombooloomba Dam is a concrete gravity dam with a controlled spillway across the Tully River, located west of Tully and south, southeast of Ravenshoe in Far North Queensland, Australia. Built for the purpose of hydroelectric power generation, the dam creates the reservoir, Lake Koombooloomba.
The Serpentine Dam is a rockfill embankment dam with a concrete face and a controlled spillway across the Serpentine River, located in the South West region of Tasmania, Australia.
Corra Linn Dam is a concrete hydroelectric dam on the Kootenay River between the cities of Castlegar and Nelson, in the West Kootenay region of southern British Columbia.
The Dukan Dam is a multi-purpose concrete arch dam in As Sulaymaniyah Governorate, Kurdistan Region of Iraq. It impounds the Little Zab, thereby creating Lake Dukan. The Dukan Dam was built between 1954 and 1959 whereas its power station became fully operational in 1979. The dam is 360 metres (1,180 ft) long and 116.5 metres (382 ft) high and its hydroelectric power station has a maximum capacity of 400 MW.

The Siah Bisheh Pumped Storage Power Plant, also spelled Siyāhbisheh and Siah Bishe, is located in the Alborz Mountain range near the village of Siah Bisheh and 48 km (30 mi) south of Chalus in Mazandaran Province, Iran. The power plant uses the pumped-storage hydroelectric method to generate electricity during periods of high energy demand, making it a peaking power plant, intended to fulfill peak electricity demand in Tehran 60 km (37 mi) to the south. When complete it will have an installed generating capacity of 1,040 megawatts (1,390,000 hp) and a pumping capacity of 940 megawatts (1,260,000 hp). Planning for the project began in the 1970s and construction began in 1985. It was delayed from 1992 until 2001 and the first generator went online in May 2013. The remaining generators were commissioned by 1 September 2015. The power plant is the first pumped-storage type in Iran and will also use the country's first concrete-face rock-fill dam – two of them.
Huites Dam, officially known as Luis Donaldo Colosio Dam, is located on the Rio Fuerte in northwestern Sinaloa, Mexico 130 kilometres (81 mi) northeast of Los Mochis. The 162-metre (531 ft)-high, hybrid concrete arch-gravity dam impounds a reservoir called Lago Huites or Presa Luís Donaldo Colosio and is owned by the Comisión Federal de Electricidad.
