The Shintoyone Dam (新豊根ダム) is a multipurpose dam in the village of Toyone in the Aichi Prefecture of Japan.
History
The potential of the Tenryū River valley for hydroelectric power development was realized by the Meiji government at the start of the 20th century. The Tenryū River was characterized by a high volume of flow and a fast current. Its mountainous upper reaches and tributaries were areas of steep valleys and abundant rainfall, and were sparsely populated. However, the bulk of investment in hydroelectric power generation in the region was centered on the Ōi River, and it was not until the Taishō period that development began on the Tenryū River. With the completion of the Sakuma Dam, one of the tallest dams in Japan, on the main stream of the Tenryū River, developers turned their eyes to the confluence of the Ōnyugawa (大入川), a major tributary of the Tenryū River, and the Ōchisegawa (大千瀬川) in Aichi Prefecture. The Ōnyugawa was also of interest in that it was prone to flooding. Preliminary design work began in 1962, with construction beginning in 1969 after some opposition from the 100 households who needed to be relocated, and over increasing controversy regarding the issues of dams on the Tenryū and Ōi rivers rapidly filling with sand and silt from the mountains upstream, with the resultant reduction of the amount of sand and silt reaching the river mouth creating problems with coastal erosion. Construction was completed by the Kumagai Gumi in August 1973.
Design
The Shintoyone Dam is a concrete arch dam with a height of Script error: No such module "convert". meters and a length of Script error: No such module "convert".. It impounds a reservoir called Script error: No such module "Nihongo". with a surface area of Script error: No such module "convert".. The catchment basin for the reservoir is Script error: No such module "convert". square kilometers. The reservoir is connected by two Script error: No such module "convert". tunnels to the Script error: No such module "convert". pumped-storage hydroelectric power plant constructed next to the Sakuma Dam which creates the lower reservoir of the scheme.[1]
Surroundings
The Shintone Dam Reservoir is a popular attraction as the surrounding area is part of the Tenryū-Okumikawa Quasi-National Park.
