Houston, TX, August 6, 2026 —
Federal officials have decided against releasing cool water from Lake Powell, a significant reservoir along the Colorado River. This decision means the reservoir will not be managed to benefit the habitat of the threatened humpback chub fish.
The reservoir is currently operating at only 23% of its capacity. This low water level is attributed to a combination of overuse and the ongoing impacts of climate change on the region’s water supply.
By withholding the cool water release, the decision prioritizes the ongoing generation of hydropower from the facility. The consequence of this action is that warmer water will be released from Lake Powell. This warmer water is expected to facilitate the spawning of invasive smallmouth bass.
Environmental advocates have expressed concern that the increased spawning of smallmouth bass could pose a further threat to native fish populations situated downstream from the reservoir. The long-term ecological impacts of this decision on the Colorado River ecosystem remain a significant point of discussion.
