Glen Canyon Dam 2013 High Flow Experimental Release


The Department of the Interior conducted the second high flow experimental release from Glen Canyon Dam under the innovative science-based protocol approved in 2012. The protocol calls for conducting more frequent high flow experimental releases from the dam timed to occur following sediment inputs to the Colorado River from downstream tributaries. The second such release based on the new guidelines began on November 11, 2013.

Temendous sediment resources approximately three times larger than the volume available in the fall of 2012 was deposited beginning in July 2013, the result of significant rainstorm and monsoonal activity.
