Satellite sees green-up along Colorado River's Delta after experimental flow

A pulse of water released down the lower reaches of the Colorado River last spring resulted in more than a 40 percent increase in green vegetation where the water flowed, as seen by the Landsat 8 satellite. The March 2014 release of water - an experimental flow implemented under a U.S.-Mexico agreement called "Minute 319" - reversed a 13-year decline in the greenness along the delta.
