Glen Canyon Dam 2012 High Flow Experimental Release
With the new science-based protocol in place for conducting more frequent high flow experimental releases from Glen Canyon Dam, the Department of the Interior will initiate the first such release based on the new guidelines beginning November 18, 2012.
The protocol allows for more frequent HFE releases to be conducted when the right conditions exist, through the year 2020. The goal is to determine the effectiveness of multiple HFE releases in rebuilding and conserving sandbars, beaches, and associated backwater habitats that have been lost or depleted since the dam's construction and operation.
