US Bureau of Reclamation approves releasing cold water from Glen Canyon Dam, Arizona, to protect native fish species from invasive smallmouth bass.
The US Bureau of Reclamation has approved releasing cold water from the Glen Canyon Dam in Arizona to protect the humpback chub and other native fish species from invasive smallmouth bass.

This move is part of efforts to maintain the native fish population in the Colorado River area below the Glen Canyon Dam.
