The Wadagawa Dam is a gravity dam on the Wadagawa River (a tributary of the Shō River) in Tonami, Toyama Prefecture, Japan. It was constructed between 1962 and 1967. The dam has an associated 7.4 MW hydroelectric power station which was commissioned in 1968. Of the dams in the Shō River system, it is the furthest downstream. [2]

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.

The Kurobe Dam (黒部ダム) or Kuroyon Dam (黒四ダム), is a variable-radius arch dam on the Kurobe River in Toyama Prefecture, Japan. It supports the 335 MW Kurobe No. 4 Hydropower Plant and is owned by Kansai Electric Power Company. At 186 metres (610 ft) in height, it is the tallest dam in Japan. It was constructed between 1956 and 1963 at a cost of ¥51.3 billion yen. The project was a difficult engineering feat for the rapidly growing post–World War II Japan, and claimed the lives of 171 people.

Veazie Dam

The Veazie Dam was a hydroelectric dam on the Penobscot River between Veazie and Eddington in Penobscot County, Maine. In 2010 the Penobscot River Restoration Trust bought the dam from PPL Corporation based on an agreement that was signed in 2004. Deconstruction of the dam began on July 22, 2013 as a part of an extensive project involving four dams to restore eleven species of sea-run fish to the Penobscot River. The Veazie Dam was the furthest downstream of the dams on the Penobscot River; now the Milford and Orono Dam dams are furthest downstream, albeit on separate side of Marsh Island. The Great Works Dam, which was 8 mi (13 km) upstream of the Veazie Dam, was removed in 2012.
