The dam is located within a gorge on a foundation of sedimentary rocks. It is a rock-fill embankment type with a central clay core. The dam is 128 m (420 ft) tall and 445 m (1,460 ft) long (535 m (1,755 ft) if the spillway section is included). Its crest is 17 m

After the Harza
Engineering Company of USA designed the dam, construction began in 1956. The reservoir began to fill in November 1961 and the dam was complete that same year. After the reservoir filled, several problems occurred. In 1967, there was a major
