Flaming Gorge is clearly a marvel of engineering, from pendulum-like “plumb lines” that help Reclamation employees ensure the 60-year-old concrete structure isn’t moving around too much, to “weep holes” that reduce pressure buildup by allowing water to seep through fissures in the canyon walls on either side of the dam. Electric lines extend upward from the blockish power plant, soaring out of the canyon through a series of transmission towers that send carbon-free energy to the Black Hills, Burbank and beyond…

The Biden administration said this month it would release an extra 500,000 acre-feet of water from Flaming Gorge Reservoir over the next year, as part of a desperate effort to stop Powell from falling so low that Glen Canyon Dam can no longer generate power. That’s on top of the 125,000 acre-feet that Flaming Gorge contributed to Powell in a first-of-its kind series of releases last year…

Hydropower has long been a backbone of the Western power grid, with rivers from the Colorado to the Columbia fueling the growth of cities including Los Angeles, Phoenix and Seattle. And even as some environmental activists campaign to demolish certain dams and restore the ecosystems they destroyed, hydropower turbines have become an increasingly valuable tool for keeping the lights on after sundown, when solar panels stop generating electricity. The threat of power shortages is real — especially on stiflingly hot summer evenings when the entire West is baking, and people have no choice but to keep blasting their air conditioners after sundown. Those are the kinds of conditions that prompted rolling blackouts in California in August 2020, with state officials warning that the potential for outages could be worse this summer.
