Spectacular Time Lapse Dam "Removal" Video

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. The reservoir draining took 1.2 hours.

Volume of Northwestern Lake was ~5 million cubic yards (Gathard 2004). Calculations of the largest outburst Lake Missoula was about 20,000 times as large (assuming a discharge at Condit Dam was ~885 m3/sec). However, the USGS calculated the discharge at 420 m3/sec, which would make the largest Lake Missoula outburst 40,000 times as great! The video does a good job of revealing the power and destruction wrought from a sudden outburst, even for a relatively small-volume event.
