- Officials will not release cool water from a Colorado River reservoir to protect threatened fish
Federal officials announced they will not release cool water this year from reservoirs like Glen Canyon Dam in northern Arizona, prioritizing concerns over hydropower generation. This decision pits the conservation of threatened fish, such as the humpback chub, against maintaining electrical power output. The issue affects a massive waterway used by seven U.S. states and Mexico, which is shrinking due to overuse and climate change.
