Nevada Water Law, Statutes, and Regulations
What this domain tests
This domain tests Nevada's prior-appropriation system and the State Engineer's authority over groundwater. Expect questions on permits, designated basins, beneficial use, domestic-use limits, protests, and the difference between a water-right permit and a completed certificate.
Core rules and concepts
- Nevada follows prior appropriation: first in time, first in right, limited to beneficial use. A water right is not created by owning land over an aquifer.
- The State Engineer administers groundwater in designated basins. An applicant must show unappropriated water and must not injure existing rights.
- A permit authorizes development; a certificate confirms the perfected right after proof of beneficial use. Holding a permit alone does not complete the right.
- Groundwater basins are managed using perennial yield, the long-term average annual supply that can be withdrawn without depleting storage. In over-appropriated basins, new permits may be denied or conditioned.
- Domestic use receives specific statutory treatment, but the exemption is limited by use, volume, and basin rules. It is not a general license to ignore permitting or well-construction requirements.
- Protests and hearings are part of the administrative process. Missing a deadline can waive participation.
Worked example
An applicant seeks 200 acre-feet per year for irrigation in a basin where the State Engineer has already committed the perennial yield. The applicant owns the land but has no earlier right. Ownership does not establish unappropriated water. The State Engineer may deny the application or impose conditions if existing rights would be injured. The applicant's remedy is through the administrative protest and hearing process, not by drilling first.
Traps that cost marks
Assuming landownership equals a water right; confusing a permit with a certificate; ignoring whether the basin is designated; and treating the domestic exemption as unlimited.
