tika Posted November 25, 2015 Posted November 25, 2015 http://www.wimp.com/spectacular-time-lapse-of-a-dam-removal/ In 2011, restoration began on the White Salmon River in Washington state. Part of the process included the disabling of the 100-year-old Condit Dam by setting off explosives within the structure. While the explosions didn’t tear the dam down, they did release the water from its reservoir, unleashing a torrent of water. It ultimately took 2 hours for the reservoir to drain but, thanks to the power of time-lapse photography, you can watch the whole process in just two minutes. Further demolition happened in 2012, and the restoration process continues to this day. If you’d like to see more time-lapse footage from how the Condit Dam project has moved forward over the years head over to White Salmon Time-Lapse. 2 Quote
danhunt Posted November 25, 2015 Posted November 25, 2015 Cool video, thanks for posting! I was amazed at how much sediment was headed downstream when the water was let loose. Quote
albertatrout Posted November 25, 2015 Posted November 25, 2015 I remember seeing this one and thinking what kind of permits/ rules you would have to follow in Alberta to remove a dam like that. Lets just say, the cost would be a bit higher up here ha ha. It's an ugly way of doing it, but really cool and highly effective. If you look up footage of that area now it's amazing how quickly it is regenerating. There was a documentary about this project as well, had a wee bit of a hippy bias but good none the less. Quote
