Is Lake Powell doomed?
On Feb. 22, 2021, Lake Powell was 127.24 feet below 'Full Pool' or, by content, about 38% full. Based on water level elevations, these measurements do not account for years of sediment (clay, silt, and sand) accumulation—the millions of metric tons on the bottom. Geologist James L. Powell said, "The Colorado delivers enough sediment to Lake Powell to fill 1,400 ship cargo containers each day." In other words, Lake Powell is shrinking toward the middle from top and bottom. The lake is down over 30 feet from one year ago, and estimates suggest it could drop another 50 feet by 2026.
