Counties with the worst droughts in Arizona
(Stacker) - More than one-fifth of the continental U.S. is currently experiencing moderate to exceptional drought, according to the U.S. Drought Monitor.
Winter storms brought heavy (in some areas, record-setting) rainfall and flooding to California, offering the state an expected two-year reprieve from widespread droughts, that covered nearly 100% of the state from 2020-22.
But in other parts of the country, especially dry conditions continue. New Mexico currently is the state with the highest drought level, covering 88.2% of the state’s area.
In periods of drought, levels of major reservoirs and rivers can fall dramatically. Groundwater systems are also affected as shrinking water supplies impact agriculture and hydropower generation while increasing wildfire risk. Periods of drought have intensified and become more frequent in recent years due to climate change.
Scientists predict that even in low-emissions scenarios, much of the U.S. will be drier by the end of the century.
Stacker cited data from the U.S. Drought Monitor to identify the counties in Arizona with the worst droughts in the week leading up to March 5, 2024. Counties are listed in order of percent of the area in drought conditions. “Abnormally dry” is not considered to be a drought, but is included as a separate data point.
Additional data for the state overall is also included. Any counties which are not experiencing drought are not included in the list. Counties are listed in order of drought severity.
