The dam is still 30% empty and the floodgates have been opened a few times already. The floodgates are opening because of old regulations that require water to be released when Folsom Lake rises by a specified amount.

There is some impressive time lapse of the lake filling at over 1' per day. All good. Not the end of the drought of course but welcome.
That graphic typo was pretty basic (it's Nimbus Dam, not Numbus, and I know that just as an occasional passerby).
EDIT: they caught it later; it's corrected at 1:07
“the most amount of water” is a really funny grammatical concept. Who writes that stuff?
