Western US States Using Up Ground Water At an Alarming Rate
sciencehabit (1205606) writes A new study shows that ground water in the Colorado basin is being depleted six times faster than surface water. The groundwater losses, which take thousands of years to be recharged naturally, point to the unsustainability of exploding population centers and water-intensive agriculture in the basin, which includes most of Arizona and parts of Colorado, California, Nevada, Utah, New Mexico, and Wyoming. Because ground water feeds many of the streams and rivers in the area, more of them will run dry.

A decade is a really short period of time for weather/water levels/ etc.
