Groundwater Use for Stock Watering

What This Bill Does

  • Allows holders of IGFRs in any AMA, not just initial AMAs, the right to annually withdraw up to 10 acre-feet of groundwater for domestic or stock watering from wells used for irrigation on certificated acres if specific conditions apply.
  • Requires that withdrawn groundwater must be used on the same land and for the same purpose as it was being used before the designation of the AMA or June 12, 1980.
  • Specifies that IGFRs can only be transferred with the land to which they are attached.

Who It Names or Affects

  • People who hold certificates of irrigation grandfathered rights (IGFR) in any active management area (AMA).
  • The Arizona Department of Water Resources (ADWR), which oversees the issuance and regulation of IGFRs.
  • Livestock owners who rely on groundwater for watering their animals.

Irrigation Grandfathered Right (IGFR)

FACT SHEET FOR
S.B. 1287

stock watering;
active management areas

Purpose

Allows a person who holds a certificate of an irrigation grandfathered
right (IGFR) in any active management area (AMA), rather than in an initial
AMA, the right to annually withdraw up to 10 acre-feet of groundwater for
domestic purposes or stock watering from a well or wells the holder is using to
withdraw groundwater for irrigation use on the certificated acres and use the
groundwater if statutorily outlined conditions apply.

Background

In an AMA, a person who was legally withdrawing and using
groundwater as of the date of the designation of the AMA or who owns land
legally entitled to be irrigated with groundwater has the right to withdraw or
receive and use groundwater as determined by the Director of the Arizona
Department of Water Resources (ADWR). There are three categories of
grandfathered rights: 1) non-irrigation grandfathered rights associated with
retired irrigated land; 2) non-irrigation grandfathered rights not associated
with retired irrigated land; and 3) IGFRs. In an AMA, a person who owns land
which was legally irrigated in whole or in part with groundwater at any time
during the five years preceding January 1, 1980, for initial AMAs or the date
of the notice of the initiation of designation procedures or the call for the
election for subsequent AMAs, which is capable of being irrigated and which has
not been retired from irrigation for a non-irrigation use has the right to use
groundwater for the irrigation of such land. The owner of an IGFR may convey
the right only with the land to which the right is appurtenant (A.R.S. ��
45-462
;
45-465
; and
45-472
).

A person who holds an IGFR in an initial AMA has the right to annually
withdraw up to 10 acre-feet of groundwater for domestic purposes or stock
watering from a well or wells the holder is using to withdraw groundwater for
irrigation use on the certificated acres, if: 1) as of June 12, 1980,
groundwater withdrawn from the well or wells was being used for domestic
purposes or stock watering; and 2) no certificate of type 2 non-irrigation
grandfathered rights has been issued by the Director of ADWR. Groundwater
withdrawn under these conditions may only be used on the same land and for the
same purpose of which groundwater withdrawn from the well or wells was being
used as of June 12, 1980 (
A.R.S.
� 45-465.03
).

There is no anticipated fiscal impact
to the state General Fund associated with this legislation.
