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 need for a dam primarily for flood control was emphasized by Typhoon Ione in September of the following year, which killed an additional 1956 people. The dam was completed by the Kajima Corporation in 1968

Design

The Shijūshida Dam is a concrete gravity arch dam. The project was made complicated by the extreme acidity of the water (reaching pH of 4.0) due to runoff from the Matsuo mine upstream. This acidity resulted in the use of special concrete and alloy materials. Generators for the associated hydroelectric power plant product 15,100 KW of electricity.
