Unazuki Dam, Gravity dam in Kurobe, Japan
Unazuki Dam is a concrete barrier across the Kurobe River that stretches 190 meters and rises 97 meters above the riverbed. The structure holds back a large reservoir and manages water flow through the surrounding mountain landscape.
The dam was completed in March 2001 as the final addition to a series of five dams built along the Kurobe River system. It was constructed to address water management needs in the region.
Engineers and water management professionals from various regions visit the dam to study its advanced sediment control methods and technological implementations.
The dam sits in a mountain valley where weather can change quickly, so plan your visit carefully and bring appropriate clothing. The surrounding area offers limited facilities, so prepare accordingly before arriving.
Between June and August, coordinated flushing operations remove sediment buildup from the river system to keep water flowing properly. These operations are timed to match natural flood seasons.
