These are heady days for dam-busters. Six dams in the American West have come down in the past year. Last month the Federal government agreed to remove four more dams on the Klamath River.
Dams are like clogs in the earth’s arterial system. Removing dams is like performing angioplasty for the planet. On rivers from the Amazon to the Yangtze we’ve dammed enough water to change the speed that the planet spins. Dams decimate communities in the flood zones, prevent fish from swimming up river, and often bury archaeological and geographic treasures.
We’re now learning that some of those dams are also wasting the water they were built to protect.
The holy grail for dam-busters is Glen Canyon Dam in Southern Utah. The giant concrete dam on the Colorado River forms the second largest American reservoir, Lake Powell. Today it’s less than half full, with a giant bathtub ring stain formed at an old high-water mark. Before inundation, Glen Canyon was an explorable maze of Native American archaeological sites and 2,000 side canyons. Today Lake Powell is a popular houseboating destination. You can steer your houseboat to the pinnacle of a three hundred foot spire that’s 90% submerged.
