Characteristics

The dam was constructed between 1964 and 1968 with the primary purpose of hydroelectric power production. It is 103 m (338 ft) tall and creates Rama Lake. The dam's power station is located underground about 9.7 km (6.0 mi) to the southeast and discharges back into the Rama River. It contains two 80 MW Francis turbine-generators for an installed capacity of 160 MW. The difference in elevation between the reservoir and power station afford a hydraulic head (water drop) of 325 m (1,066 ft).^[1][5]

History

The power station ceased operations between 1993 and 1996 due to the Bosnian War.
