| The failure had several causes, but the most infamous one is that
| the failsafe gauge had been moved above the top of the dam wall

|
| The reservoir was repaired and as far as I know continues to
| operate. I backpacked in the area several times and the dam wall
| has a striking appearance on the horizon.
