Does Arizona have enough water to deal with drought and other challenges?
The Valley's rapid growth likely wouldn't have been possible without water from the Colorado River via the Central Arizona Project. But the Southwest's ongoing drought has some concerned about whether Arizona will have enough water for the future.
