Ground water is depleting in the Colorado River Basin

A recent study of water loss in the Colorado River Basin since late 2004, published in Geophysical Research Letters, has determined that 75 percent of the loss came from underground sources. Seven western US states (Wyoming, Colorado, Utah, New Mexico, Nevada, Arizona and California) rely on the Colorado River and its tributaries for water for both individual use and agriculture. It is estimated that agriculture by itself currently uses approximately 60 percent of Colorado River ground water.
