stock watering; active management areas

This bill clarifies groundwater rights for domestic use and livestock watering within Arizona's active management areas. It grants existing landowners with "irrigation grandfathered rights" the right to withdraw up to 10 acre-feet annually from their wells for domestic purposes (household use) or stock watering (livestock), provided the use existed on the same land as of June 12, 1980 - the date the active management area was designated. If withdrawals are separately measured with an approved device, they are exempt from conservation rules; otherwise, they count toward irrigation quotas. The right is tied to the irrigation right and ends if the irrigation right is retired or sold for non-irrigation use.
