Uryū Dam complex
The 762nd tallest dam in the world
The Uryu Dam is a dam complex in Kamikawa Subprefecture, Hokkaido, Japan on the Uryu River. It consists of two dams. It is a power generation dam managed by Hokkaido Electric Power Co., Inc., and is a gravity-type concrete dam with a bank height of 45.5 meters. Lake Shumarinai, which is an artificial lake, is more famous than a dam, but this lake is the largest artificial lake in Japan with a flooded area (the area of a dam lake). This record has not yet been broken since it was completed in 1943 (Showa 18) during World War II.
