March 18, 2013--USGS water study details evapotranspiration rates (Summit Voice)

At least 80 percent of the precipitation that falls in the hot and dry American Southwest is lost to evapotranspiration, U.S. Geological Survey scientists said in a new report that will help resource managers plan for the future. The study, published in the Journal of the American Water Resources, is the first to map average evapotranspiration rates across the continental United States.
