Escalation: Lake Powell Reaches Record Low Water Levels

Lake Powell dropped to 3,519.91 feet, a new record low. The reservoir is more than 20 feet lower than it was at the start of the year. It now sits about 30 feet above the point where Glen Canyon Dam’s turbines would stop producing power.

A record‑dry winter and rising temperatures helped drive the decline, leaving Powell roughly 23% full. Powell and Lake Mead are at their lowest levels in nearly seven decades, and their combined storage is the smallest since May 1957, when Glen Canyon Dam was being built.

Low water has already shifted the shoreline economy. Boat ramps have closed or been extended, and marinas have been moved to deeper water. With power generation at risk, managers will not release cold, deep water from Powell this year to cool the river for threatened fish. Downstream temperatures sit near 69 F, above the 60 F trigger for weeks, raising the risk of smallmouth bass spawning that threatens the humpback chub.
