Fujiwara Dam
Fujiwara Dam (藤原ダム) is a gravity dam on the Tone River in Gunma Prefecture of Japan. It is located 14 km (9 mi) north of Minakami. It was constructed between 1951 and 1957. The dam itself supports a single Francis turbine hydroelectric generator with a 23 MW capacity which was commissioned in 1957. The reservoir created by the dam serves as the lower reservoir for the 1,200 Tamahara Pumped Storage Power Station which was commissioned in 1986. The dam is 95 m (312 ft) high and withholds a reservoir with a 52,490,000 m3 (42,554 acre⋅ft) storage capacity.[1][2]
