Yes, but this figure is also a little misleading. For example, if you live in San Francisco or several other cities in the Bay Area, 80% of your water comes from the Hetch Hetchy system. Very little of that water is used for agriculture. If the snowpack is 30% of normal, than the water entering the system is 30% of normal, and that's a problem.
