Scientists assess results of man-made flood into Colorado River’s dry bed

In March 2014, water flooded the Colorado River’s dry bed. This event, called a pulse flow, occurred when the Morelos Dam, near the United States–Mexico border and Yuma, Arizona, opened its gates and filled the dry bed for eight weeks. The event, similar to the spring floods that halted after the river was dammed, allowed water to reach the Gulf of California for the first time since 1997.
