NV Rev Stat § 534.110 (2021)
2021 Nevada Revised Statutes|Chapter 534 - Underground Water and Wells|NRS 534.110 - Rules and regulations of State Engineer; statements and pumping tests; conditions of appropriation; designation of critical management areas; restrictions; limit to restrictions on domestic wells.

  1. The State Engineer shall administer this chapter and shall prescribe all necessary regulations within the terms of this chapter for its administration.  2. The State Engineer may:  (a) Require periodical statements of water elevations, water used, and acreage on which water was used from all holders of permits and claimants of vested rights.  (b) Upon his or her own initiation, conduct pumping tests to determine if overpumping is indicated, to determine the specific yield of the aquifers and to determine permeability characteristics.  3. The State Engineer shall determine whether there is unappropriated water in the area affected and may issue permits only if the determination is affirmative. The State Engineer may require each applicant to whom a permit is issued for a well:  (a) For municipal, quasi-municipal or industrial use; and  (b) Whose reasonably expected rate of diversion is one-half cubic foot per second or more,  to report periodically to the State Engineer concerning the effect of that well on other previously existing wells that are located within 2,500 feet of the well.  4. 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 point of diversion. 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.  5. This section does not prevent the granting of permits to applicants later in time on the ground that the diversions under the proposed later appropriations may cause the water level to be lowered at the point of diversion of a prior appropriator, so long as any protectable interests in existing domestic wells as set forth in NRS 533.024 and the rights of holders of existing appropriations can be satisfied under such express conditions. At the time a permit is granted for a well:  (a) For municipal, quasi-municipal or industrial use; and  (b) Whose reasonably expected rate of diversion is one-half cubic foot per second or more,  the State Engineer shall include as a condition of the permit that pumping water pursuant to the permit may be limited or prohibited to prevent any unreasonable adverse effects on an existing domestic well located within 2,500 feet of the well, unless the holder of the permit and the owner of the domestic well have agreed to alternative measures that mitigate those adverse effects.  6. 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 and all vested-right claimants, and if the findings of the State Engineer so indicate, except as otherwise provided in subsection 9, the State Engineer may order that withdrawals, including, without limitation, withdrawals from domestic wells, be restricted to conform to priority rights.  7. The State Engineer:  (a) May designate as a critical management area any basin in which withdrawals of groundwater consistently exceed the perennial yield of the basin.  (b) Shall designate as a critical management area any basin in which withdrawals of groundwater consistently exceed the perennial yield of the basin upon receipt of a petition for such a designation which is signed by a majority of the holders of certificates or permits to appropriate water in the basin that are on file in the Office of the State Engineer.  The designation of a basin as a critical management area pursuant to this subsection may be appealed pursuant to NRS 533.450. If a 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, unless a groundwater management plan has been approved for the basin pursuant to NRS 534.037.  8. In any basin or portion thereof in the State designated by the State Engineer, the State Engineer may restrict drilling of wells in any portion thereof if the State Engineer determines that additional wells would cause an undue interference with existing wells. 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 NRS 533.450.  9. 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 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.
