HistoryEdit
Yomasari Dam was designed as a multi-purpose dam, to provide for flood control in the event of heavy rains or typhoons, which had potential to flood downtown Hachinohe. The reservoir created was intended to provide water for tap water, as well as agricultural and industrial purposes, and to create a new recreational area for fishing and boating for the residents of Hachinohe. However, there is no hydroelectric power station associated with the dam.
Preliminary design work began on the Yomasari Dam in 1976, with main construction beginning in 1989, and was completed by 2003 by a consortium of the Obayashi Corporation, Sumitomo Mitsui Construction, and Tekken Corporation.
DesignEdit
The Yomasari Dam is a hollow-core concrete gravity dam with several central spillways.
