Washi Dam
The 772nd tallest dam in the world
Washi Dam (Washi damu) is a hydroelectric power Arch-gravity dam on the Kuzuryū River system in the city of Ōno in Fukui Prefecture, Japan. The dam has a height of 45 meters and is owned by the Electric Power Development Company (J-Power). It is paired with the Nagano Power Station and the Kuzuryu Dam as a Pumped-storage reservoir. Construction of the dam began in 1957; however, the pumped storage facility was not part of the original design and was added later at the insistence of the Ministry of International Trade and Industry. The dam was completed in 1968.
