摘要

Ouchi area is located around in the center of Ishikawa Prefecture. Now, the irrigation system covers around 1.400 ha of this area. In 1974, 250 ha of new farm land was reclaimed from Ouchi lagoon. Before the reclamation, water resources in this area were four rivers flowing into the lagoon and "Tameike" in the mountain area near the farm land. However, because of shallow river basin and the old custom of the use of water, it was difficult to supply sufficient irrigation water for the new farm land. In order to solve this problem, the outlet of the lagoon was closed by a gate so that the lagoon might have a function as a reservoir. Moreover, return water from the farm land was stored in catch canals constructed along the lagoon. And, by 18 pumps settled in the catch canals, the used water is repeatedly supplied for irrigation. This paper shows the repetitive use system of irrigation wacer of this area, and the volume of pumped up water in each.
