Unbong Dam, Hydroelectric power station in Ji'an, China and North Korea.
The Unbong Dam stretches 828 meters across the Yalu River, featuring four Francis turbine-generators that produce substantial electrical power for both nations.
Construction of the dam started in 1942, halted in 1945 due to World War II, resumed in 1959, and reached completion with all generators operational by 1967.
The dam represents a joint infrastructure project between China and North Korea, with two generators dedicated to each country's electrical grid system.
The concrete structure contains 21 floodgates capable of managing water discharge rates up to 21,900 cubic meters per second through its overflow spillway.
Two long tunnels, measuring 775 and 759 meters, transfer water from the dam's right abutment across a ridge to the power generation station.
