Overview
Kadogawa Dam is a prefecture-run rockfill dam built across the upper reaches of the Kadogawa River, a Class B river running through Uozu City in Toyama Prefecture. Standing 58.5 meters high with a crest length of 180 meters, it was built solely for flood control.
Highlights
- ●The rockfill embankment, 58.5 m high and 180 m long
- ●The embankment face lined with river stones from the Hayatsuki River
- ●Two roller gates used for flood-control discharge
- ●Views of the unnamed reservoir and surrounding mountains
History
Planning for the dam began after flood damage struck the area in 1969, and construction proceeded as a subsidized flood-control project with national government support, completed on October 30, 1978. The face of the embankment is covered with river stones gathered from the nearby Hayatsuki River, tying the structure to local materials.
Access
The dam sits in a mountainous part of Uozu City with no public transport service, so visiting by car is the practical option. It is advisable to check official Toyama Prefecture or Uozu City sources in advance for road conditions and whether viewing is permitted.
Best season
Roads around the dam are generally easier to travel from spring through autumn, when snow is less of an issue. Winter visits require caution due to snow and icy conditions.
