From Times wire reports
Workers at the Glen Canyon Dam are preparing to shut off bypass gates that have been pouring billions of extra gallons of water into the Colorado River for the past several days.
The release created a flood in the Grand Canyon designed to mimic the natural ones that used to nourish the ecosystem by spreading sediment.
The closing of the gates at the dam near the Utah-Arizona border is expected to be completed by this afternoon.
