Arizona Department of Water Resources field hydrologists conducting “basin sweep” to collect water level measurements in the Western Planning Area: Butler Valley, Harquahala, McMullen Valley, Ranegras Plain, and Tiger Wash Basins
PHOENIX – Beginning the week of January 1st, 2022, and scheduled to continue for multiple months, Arizona Department of Water Resources (ADWR) field services staff will be making an extensive effort to measure water levels in wells in the Western Planning Area (WPA): Butler Valley, Harquahala, McMullen Valley, Ranegras Plain, and Tiger Wash Basins. ADWR’s objective is to measure water levels at hundreds of wells in these groundwater basins. This survey of wells – or basin “sweep,” as it is known – was last conducted in winter 2016 for the WPA. The Harquahala Irrigation Non-Expansion Area (INA) will also be included in the basin sweep as it is contained within the Harquahala Basin.
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. 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.
This basin sweep covers an area generally in the western to southwestern portion of the State and extends east of Plomosa and Kofa Mountains, west of Big Horn, Vulture and Harquahala Mountains, north of Eagle Tail Mountains and south of Bouse Hills, Buckskin and Harcuvar Mountains.
For more information regarding this matter, please contact Public Information Officer Shauna Evans at email@example.com or (602) 771-8079. Details about the nature of basin sweeps and groundwater modeling can be found here.
