The Koyna River is a tributary of the Krishna River which originates in Mahableshwar, Satara district, western Maharashtra, India. It rises near Mahabaleshwar, a famous hill station in the Western Ghats. Unlike most of the other rivers in Maharashtra which flow East-West direction, the Koyna river flows in North-South direction. The Koyna River is famous for the Koyna Dam and the Koyna Hydroelectric Project. Koyna Hydroelectric Project is the 2nd largest completed hydroelectric project in India. The reservoir – Shivasagar Lake, is a huge lake of 50 km in length.
The Keban Dam is a hydroelectric dam on the Euphrates, located in the Elazığ Province of Turkey. The dam is the first and uppermost of several large-scale dams to be built on the Euphrates by Turkey. Although the Keban Dam was not originally constructed as a part of the Southeastern Anatolia Project (GAP), it is now a fully integrated component of the project, which aims to stimulate economic development in Southeastern Turkey. Construction of the dam commenced in 1966 and was completed in 1974. Keban Dam Lake, the reservoir created by Keban Dam, has a surface area of 675 square kilometres (261 sq mi) and is reputedly the fourth-largest lake in Turkey after Lake Van, Lake Tuz, and the reservoir created by the Atatürk Dam.
The Ilısu Dam is a concrete-face rock-fill dam on the Tigris near the village of Ilısu and along the border of Mardin and Şırnak Provinces in Turkey. It is one of the 22 dams of the Southeastern Anatolia Project and its purpose is hydroelectric power production, flood control and water storage. When operational, the dam will support a 1,200 MW power station and will form a 10.4 billion m3 reservoir. Construction of the dam began in 2006 and was originally expected to be completed by 2016. As part of the project, the much smaller Cizre Dam is to be constructed downstream for irrigation and power. The dam has drawn international controversy, because it will flood portions of ancient Hasankeyf and necessitate the relocation of people living in the region. Because of this, the dam lost international funding in 2008. Most historical structures in Hasankeyf were moved to the new Hasankeyf prior to the filling of the dam. The dam began to fill its reservoir in late July 2019. Due to rainfall, the dam has achieved water levels up to 100m above the river bed and stored 5 billion cubic meters of water. The water level had reached an elevation of 498.2m on 1 April 2020.

It serves several purposes to include power, irrigation, flood control and municipal water supply to the city of Bursa. The dam was constructed between 1996 and 2002. Construction of the Uluabat Hydroelectric Station, which the dam supplies water to, began in 2006 and it was commissioned in 2010. The 125 m (410 ft) tall dam diverts water north through an 11.27 km (7.00 mi) long tunnel where it reaches the power station on the southern bank of Lake Uluabat. Water discharged from the 100 MW power station then enters the lake. The dam and power station are owned by the Turkish State Hydraulic Works.
Kığı Dam is a rock-fill embankment dam on the Peri River in Bingöl Province, Turkey. Its primary purpose is hydroelectric power generation and is the first dam in the Peri River cascade, serving as the headwaters. Construction began in 1998 and is backed by the Turkish State Hydraulic Works. When commissioned, it will support a 180 MW power station. Water from the reservoir will be diverted to an underground power station downstream via an 8.5 km (5.3 mi) long tunnel. In August 2015, suspected Kurdistan Workers' Party militants set fire to three cement trucks associated with the dam construction site. In January 2016, the dam was completed and the reservoir began to impound water.
