Just the power canal to Swift #2 went out. Swift Reservoir and the other two (Merwin and Yale) weren't affected. No injuries and no downstream flooding. Still, the dam at the power canal was around 100 feet high. Dam failures like this are extremely rare. Fortunately.

I haven't heard how Pacific Corps plans on operating Swift #1 since they can't discharge into the power canal (obviously). They will likely have to discharge into the main Lewis River channel, which hasn't seen regular streamflows since the 1950's. Interesting....
