As Western states haggle over reducing water use because of declining flows in the Colorado River Basin, a more hopeful drama is playing out in Glen Canyon.
Lake Powell, the second-largest U.S. reservoir, extends from northern Arizona into southern Utah. A critical water source for seven Colorado River Basin states, it has shrunk dramatically over the past 40 years.
An ongoing 22-year megadrought has lowered the water level to just 22.6% of “full pool,” and that trend is expected to continue. Federal officials assert that there are no plans to drain Lake Powell, but overuse and climate change are draining it anyway.
As the water drops, Glen Canyon – one of the most scenic areas in the U.S. West – is reappearing.
This landscape, which includes the Colorado River’s main channel and about 100 side canyons, was flooded starting in the mid-1960s with the completion of Glen Canyon Dam in northern Arizona. The area’s stunning beauty and unique features have led observers to call it “America’s lost national park.”
Lake Powell’s decline offers an unprecedented opportunity to recover the unique landscape at Glen Canyon. But managing this emergent landscape also presents serious political and environmental challenges. In my view, government agencies should start planning for them now.
Such a shame that Glen Canyon could once again become the boring inhospitable no mans land it once was after being such a treasured beautiful national oasis for so long. Hopefully water conservation, and mother nature will align to save Lake Powell, and allow it to continue to be one of the most amazing places on earth for all to enjoy!
