History Shijūshida Dam is the fourth in a series of five multipurpose dams built directly on the main stream of the Kitakami River, starting with the Tase Dam in 1941. The project was launched by the Economic Stabilization Bureau in 1947 following Typhoon Kathleen in September 1947 (which killed 1547 people).

The dam was first completed by the Kajima Corporation in 1968. Design The Shijūshida Dam was designed as a concrete gravity arch dam; however, since the rocks on both banks were weak, the dam was completed as a hybrid design with earthen dams on the sides and a concrete gravity dam in the center. The project was complicated by the extreme acidity of the water (reaching pH of 4.0) due to runoff from the Matsuo mine up ...

Yakeishi (1548 meters). At its highest point it is called the and flows south until it crosses National Route 397. There it turns west and follows 397 until it is stopped by the Ishibuchi Dam. In 2013 a new dam was scheduled to be completed a little downstream called the Isawa Dam. When this dam is completed the Ishibuchi Dam and reservoir will be completely flooded. Many local residents are opposed to the construction of such a large dam as the water is being impounded to provide drinking and irrigation water for use in other places. Another fear is that the great weight of the water will trigger an earthquake destroying the dam and causing a major flood. One worker on the new dam was killed by a rockslide in the 2008 Iwate–Miyagi Nairiku earthquake. The Isawa River continues its co ...
