What are water rights? In Nevada, a permit or certificate to use a quantity of public water for a stated purpose at a stated place, held separately from the land and ranked by the date it was claimed.
Nevada runs on prior appropriation. NRS 533.025 states that the water of all sources within the state, above or beneath the ground, belongs to the public, and NRS 533.030 says it may be appropriated for beneficial use. What an owner holds is therefore a right to use water, granted as a permit and perfected as a certificate, and it is a property right distinct from the parcel: it can be sold, leased or transferred on its own. Every right carries a priority date, a source, a manner and place of use, and a duty in acre-feet a year. In a short year the older priority date is served first, which is the whole of first in time, first in right. The State Engineer at the Division of Water Resources administers the system, with groundwater under NRS chapter 534.
A rural parcel gets water one of two ways. A domestic well is exempt from the permit requirement under NRS 534.180 where the draught does not exceed 2 acre-feet a year, with registration required in basins the State Engineer designates and a plugging obligation for wells drilled after July 1981 within 1,250 feet of a municipal system once service reaches them. Otherwise the water has to come from appropriated rights bought from an existing holder and transferred to the parcel by application. Many Nevada basins are fully appropriated and closed to new applications, so on those the second route is the only route and the price is whatever a seller of rights asks.
When a listing says water rights included, the useful response is to ask for the permit or certificate numbers and look them up in the State Engineer's records: the acre-feet, the manner of use, the point of diversion, the place of use and whether the right is in good standing, since rights can be forfeited after years of non-use. One acre-foot is about 325,851 gallons. Inside the valley this is mostly moot, because service comes from a Southern Nevada Water Authority member utility and the parcel does not carry its own right.
A worked example
A 10-acre parcel outside the valley lists at $310,000 with 3 acre-feet of certificated irrigation rights. The domestic well exemption under NRS 534.180 would cover 2 acre-feet a year on its own, so the extra right is what makes the pasture possible. Buying an equivalent right on an open basin can run into tens of thousands of dollars per acre-foot in public figures, which is why the certificate number belongs in the offer.

Questions people ask
Do water rights transfer with the property?
Only if the deed and the contract say so. A Nevada water right is a separate property right with its own permit or certificate, and it can be sold away from the land, so a parcel that had rights a decade ago may not have them now. Ask for the numbers and check them against the State Engineer's records before closing.
Do you need water rights for a house on a well?
Not for an ordinary domestic well. NRS 534.180 exempts a well drawing no more than 2 acre-feet a year from the permit requirement, though the State Engineer can require registration in designated basins and a well within 1,250 feet of a municipal system may have to be plugged once service is available. Irrigation, livestock and commercial use are a different question and need a right.
