On Wednesday, U.S. authorities started a man-made flood in the Grand Canyon in an attempt to restore the canyon's ecosystem. Three hundred thousand gallons (1,135,623 liters) of water per second gush from Arizona's Glen Canyon Dam during a media event on Wednesday. Secretary of the Interior Dirk Kempthorne pulled a lever releasing water from the Glen Canyon Dam, which regulates the flow of the Colorado River. He said the flooding is meant to help redistribute sediment deposits to rebuild beaches downstream.
Completed in 1963, the Glen Canyon Dam did away with the river's natural spring floods and generally caused the water to become cooler and clearer, sending some native fish species to extinction.
But, the superintendent of Grand Canyon National Park, Steve Martin fears there are non-environmental motives for this artificial flooding. He said to a newspaper that the timing was designed to please hydroelectric power producers. Link
