Lake Powell, a key reservoir on the Colorado River, is shrinking toward “dead pool,” which means water won’t flow downriver anymore — and that could in turn pinch Wyoming’s municipal and industrial water supplies with more demand from Flaming Gorge Reservoir. Lake Powell, on the Utah-Arizona state line, is in dire condition, USA Today reported. By next spring, it’s expected to fall into “minimum power pool,” meaning having barely just enough water to generate hydroelectric power at Glen Canyon Dam. If it falls even farther, that could put the reservoir at “dead pool,” or unable to generate hydroelectric power, according to reports. That’s despite roughly 1 million acre-feet expected to be pulled from Flaming Gorge Reservoir on the Wyoming-Utah state line and sent downriver through Wyoming to replenish Lake Powell.
