This is an old video, but the first I’ve seen of it. It’s like the morning coffee just hit.

October 28, 2011 — The White Salmon River in Washington state is flowing again as the nearly 100-year-old Condit Dam was disabled with explosives Wednesday. The reservoir draining took about 2 hours. Further demolition is scheduled in 2012. The event is a significant milestone for river restoration and dam removal nationwide.

Per Mental Floss:

In the video below, we see two fascinating things: First, the effect of the dam removal downstream, as water floods back into what had been a dry riverbed for a century. Second, the effect upstream shows a restoration of the original White Salmon River, as the water level radically declines (shown in timelapse). The power of water is amazing.
