This dataset represents the three Active Management Areas (AMA) in the CAP Region. The Arizona Department of Water Resources was created by the 1980 Groundwater Code to manage Arizona's water resources. Active Management Areas (AMA) were established by the Groundwater Code in areas where competition for groundwater is most severe. The Groundwater Code limits withdrawals of groundwater in AMAs to holders of grandfathered rights, service area rights, groundwater withdrawal permits, and small domestic users.
