Upper Colorado River Drought Plan Triggered for First Time
Increasingly bleak forecasts for the Colorado River have for the first time put into action elements of the 2019 upper basin drought contingency plan.
The 24-month study released in January by the Bureau of Reclamation, which projects two years of operations at the river’s biggest reservoirs, showed Lake Powell possibly dipping below an elevation of 3,525 feet above sea level in 2022. That elevation was designated as a critical threshold in the agreement to preserve the ability to produce hydropower at Glen Canyon Dam.
