Arizona is currently in our 21st year of a long-term drought. Drought in the West is a long-term concept where a single dry year does not constitute a drought. Since Arizona has an arid and semi-arid climate, extreme variability in precipitation is normal, and drought is characterized by a string of drier than normal years, often interrupted by a few wetter than normal years. Currently most watersheds in the state have experienced only 7 or 8 normal or wetter than normal years during the past 21 years. The deep canyon topography of the Western U.S. is ideal for creating large reservoirs, such as Lakes Mead and Powell on the Colorado River, and Roosevelt Lake on the Salt River in Arizona. The reservoirs provide an assured water supply in dry years, provided the drought does not last too long. Currently the reservoirs in the Southwest are about half full and are supplying an ever increasing population. For more information about the current status of Arizona reservoirs, see the Salt River Project (SRP) Daily Water Report.

Current Short-term Drought Status
Short term drought status will be updated each week (Thursday) as the new drought monitor is published.
Prepared by the State Drought Monitoring Technical Committee.
Current Long-term Drought Status
The long-term drought conditions across the state show degradation in the northeast and eastern mountains with expansion of Severe Drought (D2) and Extreme Drought (D3). Wildfire risk will continue to be high until the monsoon rains begin.
