| Description |
The goal of the 2023 High Flow Experiment (HFE) is to move sand stored in the river channel and redeposit it to rebuild eroded sandbars and beaches downstream of the Paria River in Grand Canyon National Park. 2023 High Flow Information from Bureau of Reclamation: <a href="https://www.usbr.gov/uc/progact/amp/ltemp.html" rel="noreferrer nofollow">www.usbr.gov/uc/progact/amp/ltemp.html</a> 2023 High Flow Information from Grand Canyon Nat. Park <a href="https://www.nps.gov/grca/learn/nature/hfe-23.htm" rel="noreferrer nofollow">www.nps.gov/grca/learn/nature/hfe-23.htm</a> This photo is from the 2018 High Flow Release: A single jet of water is exiting a river outlet tube. Several people are taking photos of the stream. NPS/M.Quinn Between November 5-10, 2018, the U.S. Department of Interior increased the release from Glen Canyon Dam for a high-flow experimental release (HFE) of approximately 38,100 cubic feet per second (cfs) for 3 days. (60 hours) The goal of the high-flow experiment was to move sand stored in the river channel and redeposit it to rebuild eroded sandbars and beaches downstream of the Paria River in Grand Canyon National Park. This release followed the science-based Protocol for High-Flow Experimental Releases from Glen Canyon Dam approved in the 2016 Long-Term Experimental and Management Plan Record of Decision for Glen Canyon Dam operations and is a component of the Department’s compliance with the Grand Canyon Protection Act of 1992. The Grand Canyon Protection Act mandates that Glen Canyon Dam be operated in a manner that protects, mitigates adverse impacts to, and improves the values for which Grand Canyon National Park and Glen Canyon National Recreation Area were established. Previous experimental releases from Glen Canyon Dam have demonstrated that it is possible to rebuild beaches and sandbars in Grand Canyon via high flows.
