February 7, 2015--Climate change will increase evaporation of Colorado River (Las Vegas Review-Journal)

The Colorado River faces a dual threat from climate change as rising temperatures increase the demand for irrigation water and accelerate evaporation at the river’s two largest reservoirs. So says a new report from the U.S. Bureau of Reclamation, which predicts 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. To view the full article visit Las Vegas Review-Journal.
