Incident Description |
The failure of a diversion canal resulted in an uncontrolled release of water from a High Hazard Dam; however, the dam itself suffered no damages. Had the uncontrolled release of water not been stopped, it is possible the erosive head-cut in the canal would have migrated into the reservoir. The canal breach was not witnessed during its initial failure; therefore, the mechanism(s)
responsible for failure must necessarily be speculated. |
