No turning back: The largest dam removal in US history begins
The largest dam removal in U.S. history entered a critical phase last week, with the lowering of dammed reservoirs on the Klamath River. On Thursday, the gate on a 16-foot-wide bypass tunnel at the base of Iron Gate dam, the lowest of those slated to be removed, was opened from a crack to 36 inches. … For the next week, water will flow through the bypass tunnel at an average rate of 2,200 cubic feet per second, draining down Iron Gate reservoir between two and four feet per day. Later this month, J.C. Boyle, the uppermost of the three dams, will be breached, followed by Copco 1. … Advocates are quick to point out that dam removal alone will not save the Klamath River’s salmon runs. However, removing the barriers will open up 76 miles of coho habitat and over 400 miles of Chinook habitat, says Shari Witmore, a fish biologist at NOAA Fisheries.
