- Subject: 2012 Fall High Flow Experiment at Glen Canyon Dam
- As announced by Anne Castle at the August 29, 2012, Adaptive Management Work Group Meeting, this fall marks the first season under a multi-year High Flow Experimental Protocol announced earlier this year by Secretary Salazar. Under this Protocol, high flow releases are linked to sediment input and other resource conditions below Glen Canyon Dam. Preliminary sediment estimates appear favorable for a high flow experimental release to occur during the period of November 18 – 25, 2012 should sediment and other conditions warrant. Reclamation’s planning activities for the high flow release through the bypass tubes are focusing on an anticipated date of November 19, 2012 for the bypass release to begin; however, no final decisions on the dates, duration or amount of the release have been made. During the High Flow Experiment, total releases from Glen Canyon Dam at full bypass may reach approximately 42,000 cfs. The total experiment, including ramping, could last anywhere from one and half to six and a half days. As more information on the potential high flow release becomes available, that information will be updated at USBR Potential HFE Link
