Arizona Department of Water Resources field hydrologists conducting “basin sweep” to collect water level measurements in the Phoenix AMA

PHOENIX- Beginning the week of December 12, 2022, and continuing through January 2023, Arizona Department of Water Resources (ADWR) field services staff will make an extensive effort to measure water levels in wells in the Phoenix Active Management Area (AMA). This survey of wells – or basin “sweep,” as it is known – was last conducted during the winter of 2016/2017. 

The data collected will be analyzed and used to obtain a comprehensive overview of the groundwater conditions and used to support scientific and water management planning efforts. Among others, data uses will include:

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

This basin sweep covers an area generally in the central portion of the state and extends west of the Phoenix Metro area past Tonopah, east near the Superstition Mountain and Globe, AZ, north of New River, AZ and south to Sacaton. The Phoenix AMA consists of the following subbasins; Hassayampa, West Salt River Valley, Lake Pleasant, East Salt River Valley, Rainbow Valley, Carefree and Fountain Hills.

For more information regarding this matter, please contact Public Information Officer Shauna Evans at smevans@azwater.gov or (602) 771-8079. Details about the nature of basin sweeps and groundwater modeling can be found here.
