| Descriptive name | ADWR Wells - Pima County Coverage | |
| File name | wells | |
| Spatial domain | Pima County | |
| Abstract | WELLS is a subset of WELLS_AZ, clipped to Pima County and containing a field (PCOWN) that records whether a well is associated with a county department. The source layer was downloaded from ADWR in March 2015. | |
| Known errors/qualifications | Wells from state registry based on reports by well owners. While required, information is voluntary. Data has not been verified by ADWR. Wells are mapped to the nearest quarter-quarter-quarter section center point, not their true physical locations on the ground. A quarter-quarter-quarter section is about 10 acres. When a quarter-quarter-quarter section has more than one well, the well points overlap each other in the GIS layer at that center point. | |
