🧱 Nampo Dam

The Nampho Dam or West Sea Dam, also known as the West Sea Barrage or West Sea Lock Gate,[a] is a tidal barrage located 15 km west of the special city of Nampho, North Korea. It is a large, eight-km-long system of dams, three lock chambers, and 36 sluices, allowing the passage of ships up to 50,000 tons. The dam closes the estuary of the Taedong River off from the Yellow Sea. It was built by the North Korean Army from 1981 to 1986, with the resources of the whole country directed to this main construction project. The West Sea Barrage Line runs over the dam.
