The Tobakochi Dam (Japanese: 鳥羽河内ダム, Tobakochi Damu) is a gravity dam located in Konosu, Ozu, Ehime Prefecture, Japan. It is situated on the Tobakochi River, a tributary of the Hiji River system on the island of Shikoku.
Location and Geography The dam is built within the geographical boundaries of Ozu City, a region known for its mountainous terrain and agricultural areas. The Tobakochi River is a minor river system that feeds into the larger Hiji River, which eventually flows into the Seto Inland Sea.
Purpose The primary function of the Tobakochi Dam is irrigation. It serves to provide a stable water supply for agricultural land in the downstream areas, supporting local farming communities and contributing to regional agricultural productivity, especially during periods of low rainfall.
Characteristics
- Type: Concrete gravity dam.
- Height: Approximately 29.5 meters (97 feet).
- Length: Approximately 106 meters (348 feet).
- Reservoir Capacity: While specific figures for the reservoir capacity are not widely publicized, it is designed to store sufficient water for its intended irrigation purposes.
History The construction of the Tobakochi Dam was completed in 1968. Its development was part of broader infrastructure projects in post-war Japan aimed at enhancing agricultural self-sufficiency and improving water management for regional development. The dam has since been operated by Ehime Prefecture.
