The Köprü Dam is an under construction gravity dam on the Göksu, the main tributary of the Seyhan River about 25 km (16 mi) northwest of Kozan in Adana Province, Turkey. Its primary purpose will be hydroelectric power generation. Construction began in 2009 and was complete in 2012.[5] On 24 February 2012, the dam's diversion tunnel seal broke while the dam was impounding the river for the first time. This resulted in 97,000,000 m3 (78,639 acre⋅ft) of water flooding the downstream area of the dam. The accident and subsequent flood killed 10 workers. Downstream communities received proper warning and no one was killed.[6][7][8]
