Scientists released 45,000 cfs from Glen Canyon Dam for 8 days in 1996 to rebuild Grand Canyon sandbars

In 1996, a controlled flood was executed in the Grand Canyon to rejuvenate its natural river dynamics. Leveraging the Glen Canyon Dam, scientists released substantial volumes of water to transport sediment downstream, with the goal of restoring sandbars that had diminished due to the dam’s existence. This initiative highlighted the potential of dam operations to contribute positively to ecological restoration, paving the way for future river management experiments.
