Colorado River from Moab Rim. Utah, USA. More than half of the streamflow in the Upper Colorado River Basin originates as groundwater. Groundwater and surface water are considered a joint entire Colorado River Basin currently supports 50 million people, and that amount is expected to increase by 23 million between 2000 and 2030. On average, 90 percent of streamflow in the Colorado River Basin originates in the Upper Basin, which is the area above Lees Ferry, Arizona. Scientific stream-flow studies are vital to a better understanding of groundwater resources. Credit: USGS
