The Togagawa Dam is a gravity dam on the Togagawa River (a tributary of the Shō River) near Taikanba village about 26 km (16 mi) southeast of Shogawa in Toyama Prefecture, Japan. It was completed in June 1974. The dam has an associated 16.1 MW hydroelectric power station 5.8 km (3.6 mi) downstream near the Senzoku Dam reservoir. It was commissioned in December 1973. [1]

Gravity dam

A gravity dam is a dam constructed from concrete or stone masonry and designed to hold back water by primarily using the weight of the material alone to resist the horizontal pressure of water pushing against it. Gravity dams are designed so that each section of the dam is stable, independent of any other dam section.

Shō River river in Japan

The Shō River has its source in Mount Eboshi in the Shōkawa-chō area of Takayama, Gifu Prefecture, Japan. After flowing for 115 km (71 mi) through the northern part of Gifu Prefecture and the western part of Toyama Prefecture, it empties into Toyama Bay.

Shōgawa was a town located in Higashitonami District, Toyama Prefecture, Japan.

Kığı Dam

Kığı Dam is a rock-fill embankment dam on the Peri River in Bingöl Province, Turkey. Its primary purpose is hydroelectric power generation and is the first dam in the Peri River cascade, serving as the headwaters. Construction began in 1998 and is backed by the Turkish State Hydraulic Works. When commissioned, it will support a 180 MW power station. Water from the reservoir will be diverted to an underground power station downstream via an 8.5 km (5.3 mi) long tunnel. In August 2015, suspected Kurdistan Workers' Party militants set fire to three cement trucks associated with the dam construction site. In January 2016, the dam was completed and the reservoir began to impound water.
