US officials will not release cool water from Glen Canyon Dam this year, protecting hydropower while threatening humpback chub

This year, federal officials have decided against releasing cool water from the Colorado River reservoirs, emphasizing the need for hydropower production over the conservation of a threatened fish species. The river and its reservoirs are facing severe depletion from overuse and climate change, while states have been unable to reach a long-term agreement on water sharing. Utilities welcomed this choice, citing concerns over the costs of alternative energy sources.
