Wells are measured by hand a few times a year, not in real time. Change compares 12-month averages to smooth out seasonal swings. Data: USGS Water Data API (USGS and ADWR measurements). Pinal, Prescott and Santa Cruz AMAs are not shown because no well there has both a long record and a recent public measurement.

Arizona Water Efficiency

Arizona uses slightly less water today than in 1957 — about 7.0 million acre-feet (2017) versus 7.1 million — while its population has grown more than sixfold, according to ADWR figures. Conservation rules under the 1980 Groundwater Management Act and the conversion of farmland to urban use are major reasons.
