The Tsiazompaniry Dam is a buttress dam on the Varahina-South River, a tributary of the Ikopa River, near Tsiazompaniry in the Analamanga Region of Madagascar. The dam was constructed by a French firm in 1956. It creates Lake Tsiazompaniry, the largest reservoir in the country, which has a surface area of 31 km2 (12 sq mi) and a storage volume of 260,000,000 m3 (210,000 acre⋅ft). A second buttress dam, 1 km (0.62 mi) northwest of the main dam helps withhold the reservoir. Water released from the dam supplies a regulated flow to hydroelectric power station at the Antelomita Dam downstream. [1] [2] Efforts to install a 5.25 MW power station at the base of the dam began in 2011. [3]

The Gardiner Dam on the South Saskatchewan River in Saskatchewan is the third largest embankment dam in Canada and one of the largest embankment dams in the world. Construction on Gardiner Dam and the smaller Qu'Appelle River Dam was started in 1959 and completed in 1967, creating Lake Diefenbaker upstream and diverting a considerable portion of the South Saskatchewan's flow into the Qu'Appelle River. The dam rises 64 metres (209 feet) in height, is almost 5 km (3.1 mi) long and has a width of 1.5 km (0.93 mi) at its base with a volume of 65,000,000 cubic meters. The dam is owned and operated by the Saskatchewan Water Security Agency.

It is Oklahoma's first hydroelectric power plant and is referred to as the longest multiple-arch dam in the world.

The Koteshwar Dam is a gravity dam on the Bhagirathi River, located 22 km (14 mi) downstream of the Tehri Dam in Tehri District, Uttarakhand, India. The dam is part of the Tehri Hydropower Complex and serves to regulate the Tehri Dam's tailrace for irrigation and create the lower reservoir of the Tehri Pumped Storage Power Station. In addition, the dam has a 400 MW run-of-the-river power station. The project was approved in 2000 and its first generator was commissioned on 27 March 2011, the second on 30 March 2011. The construction site had been inundated in September 2010 by floods. The diversion tunnel was later blocked heaving/collapse of the hill in December 2010. The spillway was commissioned in Jan, 2011. The last two generators were made operational in March 2012.

The Antelomita Hydroelectric Power Station is located in the rural commune Anjeva Gara of the Analamanga Region, Madagascar. The hydroelectric power station comprises two parts, Antelomita I and II. Both are adjacent to one another on separate water falls along the Ikopa River. Each water fall is dammed and water is diverted to the power station; each of which contains three 1.4 megawatts (1,900 hp) generators. The first two were commissioned in 1930, the second two in 1952 and the final two in 1953. Both stages have an installed capacity of 8.4 megawatts (11,300 hp). They were built by a French firm but are now owned and operated by Jirama. The Tsiazompaniry and Mantasoa Dams upstream regulate water to the power station.
