  • Mano Dam

    Mano Dam is a multi-purpose dam in Iitate Village, which is located upstream of Mano River. Completed in 1991, Mano Dam provides drinking water to Soma City, Shinchi Town, and Kashima Town. It is also used for flood control, maintenance of normal flow of river water and water quality, industrial water supply, and power generation.
  • Yokokawa Dam

    Yokokawa Dam is located upstream of Ota River. Since its completion in 1984, the dam provides water mainly for industrial purposes water for irrigation purposes.
  • Tetsuzan Dam

    Tetsuzan Dam is located 4 km upstream of Yokokawa Dam. Completed in 1938, the dam has the total reservoir capacity of 1,076 thousand m³, but the water level has been kept low since the Great East Japan Earthquake to prevent a secondary disaster.
  • Minamisoma City Hall

    Minamisoma City Hall agreed to provide the necessary cooperation in providing hydrological and morphological data when the actual research starts in fiscal 2014.
