Gosho Dam (御所ダム Gosho damu) is a multipurpose dam on the Shizukuishi River, a branch of the Kitakami River in Morioka, Iwate Prefecture, Japan, completed in 1981.[1]
History
Gosho Dam is the fifth of five large dams created in the Kitakami River valley for irrigation, industrial water, flood control and electric power generation under the aegis of the Ministry of Construction.
Design
The Gosho Dam is a hybrid design incorporating a concrete gravity dam with a central spillway together with a sloped wall rockfill dam. The dam was completed in 1981 by a joint venture of the Kajima Corporation with Nishimatsu Construction. The dam supplies the 13,000 KW Gosho Hydroelectric Power Plant.
The Gosho Reservoir created by the dam is a popular vacation location due to its ease of access to the metropolis of Morioka.
