An Extra Boost of Water is Flowing Into Grand Canyon After a Wet Winter

An extra pulse of water has been sent through the Grand Canyon this week. The Bureau of Reclamation is running a “high-flow experiment” at Glen Canyon Dam in northern Arizona, which means a big release of water designed to move and redeposit sand and sediment will make its way downstream from the dam. This experiment is the first since 2018, and comes in response to forecasts for an above average spring snowmelt in the Rocky Mountains.
