Imaichi Dam

The Imaichi Dam (今市ダム) is a concrete gravity dam on the Togawa River located 4 kilometres (2.5 mi) west of Nikkō in Tochigi Prefecture, Japan. The dam serves as the lower reservoir for the 1,050 megawatts (1,410,000 hp) Imaichi Pumped Storage Power Station, while the Kuriyama Dam forms the upper. It is owned by TEPCO and was constructed between 1979 and 1986. The reservoir can store 9,100,000 cubic metres (7,400 acre⋅ft) of water. Of that storage volume, 6,200,000 cubic metres (5,000 acre⋅ft) can be used for power generation.
