A burst of new water last spring transformed the Colorado River Delta from a mud flat into a budding greenbelt. Photos, satellite images and monitoring equipment show more and greener plants, and a higher water table, because of the artificial spring 2014 release of water into the river at the Mexican border south of Yuma. The results of the delta "pulse flow" were released Wednesday at a briefing featuring UA scientist Karl Flessa and two Tucson-based federal scientists.
