ending World War II
. In October 1959, construction on the dam recommenced and in September 1965, the first of the four 100 MW Francis turbine
-generators was operational. The last generator was operational on 4 April 1967. The 113.75 m (373 ft) tall dam creates a reservoir with a storage capacity of 3895000000 cubic metre. The dam's spillway is an overflow type with 21 floodgates and has a maximum discharge of 21900 m3/s. The dam is located before a bend in the river and its power station is located on the other side of a ridge that meets the dams right abutment. Water is delivered to the power station via two tunnels, 775 m (2,543 ft) and 759 m (2,490 ft) long. Generators 1 and 3 deliver power to China while 2 and 4 deliver to North Korea.
