1

00:00:00,070 --> 00:00:04,260

In the western United States, a long drought reduced mountain snowpack

2

00:00:04,260 --> 00:00:08,380

and river flows, causing heavy reliance on aquifers for crop irrigation

3

00:00:08,380 --> 00:00:12,460

and severe depletion of freshwater resources.

4

00:00:12,460 --> 00:00:16,570

Precipitation measurements together with GRACE data show how

5

00:00:16,570 --> 00:00:20,580

natural variations in the weather and unsustainable rates of water use

6

00:00:20,580 --> 00:00:23,707

conspired to deplete groundwater in California.
