Management Zones Map for Proposed Rules 15 and 16

The District is in the process of proposing new rules creating a “Jacob’s Well Groundwater Management Zone” and a “Regional Recharge Study Zone.”

An interactive map is provided below for well owners to determine if their well is in either one of the proposed zones. To see if your well falls into either of the zones, type in the GPS coordinates of your well in the search bar in the upper right corner of the map. If you have any questions or need any help regarding the map, please contact the HTGCD office.
