Arizona Department of Water Resources conducting “basin sweep” to collect water level measurements in the Tucson and Santa Cruz Active Management Areas & Cienega Creek and San Rafael Basins

PHOENIX – Beginning the week of February 10, and continuing for several months, Arizona Department of Water Resources (ADWR) field services staff will be making an extensive effort to measure water levels in wells in the Tucson and Santa Cruz Active Management Areas (AMAs) & Cienega Creek and San Rafael Basins. 

ADWR staff will attempt to measure water levels at hundreds of wells in these AMAs and basins.  This survey of wells – or basin “sweep,” as it is known -- will be the first such basin survey of the area since 2016. The data collected will be used for several purposes, including:

  • Analysis of water-level trends
  • Groundwater modeling
  • Water-level change maps
  • Hydrologic reports
  • Water resource planning and management

The general area covered by this basin sweep is the southern portion of the state and extends from the U.S. – Mexico border to north of Tucson.
