This is a drill: Officials rehearse for a dam bursting near Sultan
SULTAN — What would happen if a breach of the Culmback Dam sent a wall of water rushing toward the Skykomish Valley? How would people be evacuated safely, with a few hours to spare?
About 75 people took part in an exercise Wednesday to practice that scenario.
The Snohomish County Public Utility District operates the Henry M. Jackson Hydroelectric Project on the Sultan River. The 112-megawatt facility supplies clean, renewable power to about 56,000 homes in Snohomish County.

The chance of the dam breaching is extremely low, said Kellie Stickney, a PUD spokesperson. However, in the event of dam failure, water from Spada Lake would cause significant flooding to Sultan and downstream communities.
