High-flow experiment at Glen Canyon Dam to protect Grand Canyon

Not since 2008 has the Glen Canyon had a high-flow release of water, but on Monday Secretary of the Interior Ken Salazar along with Assistant Secretary for Water and Science Anne Castle, National Park Service Director Jonathan B. Jarvis and Bureau of Reclamation Commissioner Mike Connor were at Glen Canyon to see it happen. Western staff was also present to witness the long-awaited event of the Glen Canyon Dam bypass tubes being opened to initiate the High Flow Experimental release. “The experiment went well thanks to the coordination efforts between DOI and Western,” said Acting Colorado River Storage Project Manger Darren Buck.

On Nov. 19 the Glen Canyon Dam bypass tubes were opened to initiate the High-Flow Experiment.

The experiment, scheduled through 2020, allows for more frequent HFE releases to happen when the right conditions exist. This will determine the effectiveness of multiple HFE releases in rebuilding and conserving sandbars, beaches and associated backwater habitats of the Grand Canyon that have been lost or depleted since the dam’s construction and operation.

For more information about the HFE, see the DOI news release or visit Reclamation’s website.
