Comment | The dam's stone masonry collapsed due to leakage from the aging sediment control dam, which caused freezing and thawing as well as by the impact of earthquakes. Initially, there was a plan to install a concrete cutoff wall on the upstream side, but the plan was changed to grouting the dam to prevent leakage. We used a dam grouting technique to restore the dam. |
