The Tedorigawa Dam, built in 1979, is a rock-fill dam formed in the steep valley of the Tedori River. Built majorly for flood protection, the dam also provides water for hydroelectric power, factories, and consumption. The height of the bank is 153m, and the catchment area is 428.4km2.
The rocks used in the dam are made up of conglomerates sourced from nearby. The rocks belong to the Gomijima Formation of the Tetori Group, aged as Early Cretaceous rocks (146 Ma to 100 Ma).
A small parking area is available which overlooks the front of the dam wall.
A park is also available with parking, which overlooks the water.
