* The Draft Surface Water Protection Program Map is included for informational purposes only and is not to be used for regulatory decisions. It reflects the current state of the draft proposed program. The draft map will be updated as the program is amended. If you believe ADEQ has included a waterbody that should not be included on the map OR if there is an intermittent or perennial water that should be included, please contact us | Email >
