The Gura Apelor Dam is a rock-fill dam on the Râul Mare River about 35 km (22 mi) southwest of Hațeg in Hunedoara County, Romania. It sits at the point where the Lapusnicu Mare, Lapusnicu Mic and Ses Rivers form the Râul Mare.[1] It is the tallest dam in Romania. The primary purpose of the dam is hydroelectric power generation and it supports the 335 MW Râul Mare Hydroelectric Power Station which is located underground about 18 km (11 mi) to the northeast. Water from the reservoir is piped the long distance from the dam to the power station. The difference in elevation between the reservoir and the power station downstream affords a hydraulic head of 582.5 m (1,911 ft). Construction on the dam began in 1975 and the power station was operational in 1986.[2] In 2012 the dam's reservoir was drained for repairs. It is expected to be impounded again in 2014.[3]
