Trump signs Colorado River drought plan

President Donald Trump on Tuesday signed a plan to cut back on the use of water from the Colorado River, which serves 40 million people in the U.S. West.  The Colorado River drought contingency plan aims to keep two key reservoirs, Lakes Powell and Mead, from falling so low they cannot deliver water or produce hydropower. It was negotiated among the seven states that draw water from the river.Mexico also agreed to store water in Lake Mead on the Arizona-Nevada border if the U.S. legislation was approved by April 22.
