Report: Colorado River Water Evaporation Increases Due to Climate Change

A new report from the U.S. Bureau of Reclamation predicted an 8 percent increase in irrigation demand on the lower half of the Colorado River Basin and a 10 percent increase in evaporation from Lake Mead by 2080. The upper half of the Basin, above Glen Canyon Dam in Arizona, is expected to see demand for agricultural water jump by almost 23 percent, while Lake Powell loses 7 percent more water to evaporation than it did during the last half of the 20th century. The estimates are based on a projected temperature increase of about 5 degrees across the region.
