Cool time-lapse video shows the removal of a dam

In 2010, the Rogue River in Oregon had just one last barrier for fish trying to migrate along the river. That was the Gold Ray Dam. The 38-foot-high structure was part of the river for 106 years, but hadn't been a functioning hydroelectric facility since the early 1970s. So, down it came and HDRInc captured the process in this time-lapse video.

HDRInc writes, "The Rogue River flows for more than 200 miles from the Cascade Mountains to the Pacific Ocean and is one of the original eight rivers included in the Wild and Scenic Rivers Act of 1968. Mid-way along the river sits the Gold Ray Dam, which is part of an obsolete hydroelectric facility. The Oregon Department of Fish and Wildlife identified this 38-foot-high and 360-foot-long structure as a priority for removal and fish passage improvement by placing it on the Oregon Statewide Fish Passage Priority List. Removing the dam will allow for riparian restoration and improved fish passage, and will increase recreational activities by returning the river to its free-flowing condition."

A lot of thought and planning for the environment and the river's future goes into such a project, such as ensuring that the accumulated sediment is redistributed so that the course of the river stays true to its historical route and that the habitat that has been affected by the changes in the river are carefully managed. But, as PetaPixel points out, every dam removal starts with draining the water and that, sometimes, includes just blasting a hole in it:

We think the gentler, piece-by-piece version is preferable...
