The Colorado River near Moab, Utah. ​​​​​​​The entire Colorado River Basin currently supports 50 million people, and that amount is expected to increase by 23 million between 2000 and 2030. A new study shows more than half of the streamflow in the Upper Colorado River Basin originates as groundwater.
