The calendar says September, but August-like heat abounds across the American west.
Thanks to a dome of high pressure, triple-digit Septemperatures in the Pacific Northwest, California, the Intermountain West, and (of course) here in Arizona are expected through the Labor Day weekend.
In the desert, we know how to navigate the heat. Carry a water bottle everywhere. Slather on sunscreen. Wear a hat. Exercise early. Do your chores in the morning. Stay inside during the heat of the afternoon. Reemerge at sundown to catch another dazzling sunset.
But there are troubling resource ramifications for this region that lie beneath the stark beauty, beyond late-summer-heat inconveniences.
Lake Powell, our country’s second largest reservoir–it straddles the Utah and Arizona border–now stands at its lowest level since 1967.
According to a recent article on scitechdaily.com by Michael Carlowicz of the NASA Earth Observatory, on August 6, 2022, the water elevation of Lake Powell’s surface at Glen Canyon Dam was 3,535.38 feet. That’s 98 feet lower than August 2017 … and only twenty-six percent of its capacity.
In August, the U.S. Department of the Interior announced it will reduce the amount of water apportioned to states in the region.
Arizona will receive 21 percent less water from the Colorado River system in 2023. That is certain to hit farmers in the Grand Canyon State particularly hard.
Fortunately, water conservation efforts are trickling down across our state and communities like Scottsdale have begun to more aggressively manage the use of water. Plus, a wet monsoon season in our state has alleviated the drought in the short term.
But, with burgeoning population growth and climate uncertainties in this region, what will the future hold for the Colorado River basin and 40 million people–Las Vegas, Phoenix, Los Angeles, and San Diego–who rely on it for electric power and water?
