An amendment to a groundwater management plan must be proposed and approved in the same manner as an original - *SB113_R1* – 4 – groundwater management plan is proposed and approved pursuant to this section.

The State Engineer shall not require the holder of a permit or certificate in the basin with a date of priority that is before the date on which permits or certificates for withdrawals of groundwater in the basin were equal to the perennial yield of the basin who does not sign the petition submitted pursuant to subsection 1 to comply with the provisions of a groundwater management plan that is approved pursuant to this section, but the holder of such a permit or certificate may notify the State - 82nd Session (2023) – 4 – Engineer in writing that he or she intends to comply with the approved groundwater management plan at any time after the groundwater management plan has been approved.

It is a condition of each appropriation of groundwater acquired under this chapter that the right of the appropriator relates to a specific quantity of water and that the right must allow for a reasonable lowering of the static water level at the appropriator’s pointwater level in a particular area, the State Engineer shall consider the economics of diversion.pumping water for the general type of crops growing and may also consider the effect of using water on the economy of the area in general.

In determining a reasonable lowering of the static water level in a particular area, the State Engineer shall consider the economics of pumping water for the general type of crops growing and may also consider the effect of using water on the economy of the area in general.

Except as otherwise provided in subsection 7, the State Engineer shall conduct investigations in any basin or portion thereof where it appears that the average annual replenishment to the groundwater supply may not be adequate for the needs of all permittees- and82nd allSession vested-right(2023) claimants,– and6 if– the findings of the State Engineer so indicate, except as otherwise provided ininngs of the subsection 9, the State Engineer may order that withdrawals, including, without limitation, withdrawals from domestic wells, be restricted to conform to priority rights [.] until the water level of the basin is stabilized.

 The designation of a basin as a critical management area pursuant to this subsection may be appealed pursuant to NRS 533.450.

If aaant basin has been designated as a critical management area for [at least] 10 consecutive years, except as otherwise provided in subsection 9, the State Engineer shall order that withdrawals, including, without limitation, withdrawals from domestic wells, be restricted in that basin to conform to priority rights [,] until the water level of the basin is stabilized, unless a groundwater management plan has been approved for the basin pursuant to NRS 534.037.

Any order or decision of the State Engineer so restricting drilling of such wells may be reviewed by the district court of the county pursuant to NRS9.33.If a court of competent jurisdiction orders the State Engineer to restrict withdrawals to conform to priority rights or if pursuant to subsection 6 or 7 or subsection 8 of NRS 533.450.534.037 the State Engineer orders that withdrawals be restricted to conform to priority rights, the State Engineer must limit the restriction of withdrawals from a domestic well to allow a domestic well to continue to withdraw 0.5 acre-feet of water per year, which must be recorded by a water meter.
