| Descriptive name | ADWR Wells - Statewide Coverage | |
| File name | wells_az | |
| Spatial domain | Arizona | |
| Abstract | wells_az contains all the registered wells in the Arizona Department of Water Resources database for the state of Arizona. This dataset is also known as the 'wells 55 registry database. Is current to 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. This layer was downloaded from ADWR in March 2015. | |
