Denver, CO, August 7, 2026 —
Federal officials have announced that they will not release cool water from Glen Canyon Dam this year, a decision that prioritizes hydropower generation over the protection of the threatened humpback chub fish downstream. The cooler water, typically released from deeper levels of Lake Powell, is crucial for the survival of the endangered fish.
This year’s decision marks a shift that will significantly impact the dam’s ability to generate electricity. Releasing cooler water from the dam’s deeper reservoirs would have reduced the overall water available for hydropower operations.
The Colorado River system, including Lake Powell, is currently facing critically low levels. This situation is attributed to a combination of factors, including persistent overuse of water resources and the ongoing impacts of climate change. The dwindling water supply has created a complex challenge, forcing federal agencies to weigh competing interests: safeguarding native aquatic species and maintaining a reliable supply of electricity for millions of ratepayers, as well as managing associated costs.
The long-term implications of this decision for both the humpback chub population and the stability of hydropower generation in the region remain a significant concern. Officials have not provided details on alternative strategies for protecting the fish or mitigating the potential impact on energy production and costs.
