Utah Water Rights: Priority, Beneficial Use, and Forfeiture

In Utah, all water belongs to the public, and a Utah water right gives you only the right to use a specific quantity from a specific source for a specific purpose. Those rights are ranked by the date they were first established, must be put to beneficial use to stay valid, and can be forfeited after seven consecutive years of nonuse. The Utah Division of Water Rights, under the State Engineer, administers the whole system.¹

First in Time, First in Right

Utah follows prior appropriation. Whoever first diverted water from a source and put it to productive use holds the oldest priority date, and that seniority controls who gets water when the source runs short. In a dry year, a senior holder receives the full allotment before any junior holder sees a drop. If a stream carries ten cubic feet per second and a senior right calls for all ten, everyone below that priority gets nothing until the senior call is satisfied.

Priority dates are set when the original application is filed with the State Engineer, or by historical court decrees that predate the modern permitting system. The date stays attached to the right no matter how many times the land changes hands. If you’re buying property, the priority date on the associated water right matters as much as the acreage. An 1890 date is a different asset than a 2005 date, especially during drought.

Beneficial Use Is the Measure and the Limit

Utah law states plainly that beneficial use is the basis, the measure, and the limit of every water right in the state.¹ You cannot hold a right without actually using the water for a recognized purpose. Irrigation, livestock, domestic household supply, industrial processes, and power generation all qualify. Holding a right for speculation does not.

Beneficial use also caps the right. If your paperwork says two cubic feet per second but you only ever use one, the unused portion is exposed. You don’t get to stockpile an allocation on paper. The expectation is that every allocated drop is doing something productive.

How You Lose a Water Right: The Seven-Year Rule

If you stop using your water right for seven consecutive years, it becomes subject to forfeiture and can revert to the public for a new appropriation.² This rule catches more Utah property owners off guard than almost anything else in state water law. Someone inherits land with a water right, lets a decade pass without irrigating, and discovers the most valuable asset on the parcel is gone.

Your best defense is a paper trail. Irrigation schedules, pump electricity bills, crop records, delivery records from a water company, and photographs of irrigated ground all help prove continuous use. When a forfeiture dispute arises, the burden of proof sits on the owner.

The Nonuse Application

If you have a legitimate reason you can’t use the water, file a nonuse application with the State Engineer before the seven-year window closes. An approved application pauses the forfeiture clock for up to seven years, and you can file another one when it expires.² The State Engineer grants the application if you show reasonable cause. Qualifying reasons include financial hardship, physical damage to your diversion infrastructure, pending efficiency improvements, pending litigation, future public supply needs, and equipment deterioration you have a specific plan to repair.

Filing a nonuse application in time is far cheaper and simpler than trying to recover a right after forfeiture.

Water Rights Are Not the Same as Water Shares

Two different legal instruments move water around Utah, and confusing them creates real problems in property deals.

A water right is a real property interest, recorded with the county recorder and the State Engineer. It is typically appurtenant to the land, meaning it transfers automatically with the property unless the seller explicitly severs it in the sale. Shares in a mutual water company are personal property, documented by stock certificates. Transferring shares means endorsing the certificate and updating the company’s records, and shareholders pay ongoing assessments for infrastructure and delivery. Direct right holders don’t pay those assessments, but they do maintain their own diversion works at their own expense.

Before closing on Utah property, ask the question directly: does this sale include a water right, water company shares, both, or neither? A water right gives you direct authority over an allocation. Shares give you a proportional claim on whatever the company delivers, subject to its bylaws and board.

Getting a New Water Right

A new right starts with an application to appropriate unappropriated water, filed with the State Engineer. The application has to describe the source, point of diversion, quantity, and intended beneficial use. Filing fees scale with the volume requested, running from $150 for small quantities up to $1,000 for the largest rights.³

The Division publishes notice of the application so existing users can file a protest if they believe their rights would be harmed. The State Engineer must approve the application if there is reason to believe unappropriated water exists in the source, the new use will not impair existing rights, the project is physically and economically feasible, and the applicant has the financial ability to complete the works. The application must also be filed in good faith, not for speculation or monopoly.⁴ An application that would unreasonably affect public recreation, the natural stream environment, or general public welfare can be denied.

Approval is not the finish line. The State Engineer sets a deadline by which you must file proof that you have actually diverted the water and put it to beneficial use. Miss that deadline and the approval lapses. Treat the proof deadline the way you’d treat a tax deadline.

Changing an Existing Right

If you already hold a right but want to move the point of diversion, change where you apply the water, or shift from one type of use to another, you file a change application rather than a new appropriation. The fee schedule is the same.³ The Division publishes notice, users can protest, and the State Engineer evaluates whether the change would impair other rights.⁴

A change application cannot enlarge the original right. You can move water from one field to another; you cannot use the process to claim more water than the right allowed. And don’t treat a change application as a formality. If downstream users can show your proposed change would reduce their available water, the State Engineer will deny it.

Looking Up a Right Before You Act

Every recognized water right in Utah carries a unique Water Right Number issued by the Division of Water Rights.⁵ The Division keeps a documentary file (scanned applications, correspondence, and historical records) and a computerized database for each one. When the two conflict, the documentary file controls.

You can search the online database by water right number, owner name, water source, point of diversion coordinates, or place of use, and there is a map-based tool for geographic searches. It’s free and public, and it should be the first stop before buying property, filing an application, or investigating a neighbor’s claim.

Any filing you make will need to pin down several specifics:

The source: the specific well, creek, spring, or reservoir.
The point of diversion: exact coordinates, typically a distance from a Public Land Survey System section corner.
The quantity: cubic feet per second for flowing water, acre-feet for stored water.
The priority date: from the original application or decree.
The nature of use: irrigation, domestic, industrial, and so on.

Incomplete applications get returned, and each round of corrections pushes your effective filing date later.

Wells and Groundwater

Groundwater in Utah is appropriated through the same system as surface water. Drilling a well requires both a water right and a licensed well driller, and the Division regulates the drilling, construction, deepening, repair, and abandonment of all water production wells regardless of depth, including domestic, irrigation, livestock, commercial, and industrial wells.⁶ You can’t drill on your own land simply because you own the surface. An unpermitted well can trigger enforcement.

Replacing an existing well has its own rules. A replacement within 150 feet of the original point of diversion goes through an expedited approval at the regional office. Anything farther requires a full change application for the new point of diversion, with notice and protest.

If Your Area Is Under General Adjudication

In some basins, the State Engineer initiates a general adjudication to determine every right on a source at once. The process can be triggered when five or more water users, or a majority of users on a source, petition the State Engineer to investigate.⁷ These proceedings can run for decades.

Deadlines are the thing to watch. Every claimant on the source receives a summons and must file a written statement of claim within 90 days. Fail to file, and you are permanently barred from asserting that right. After the State Engineer completes a hydrographic survey and files a proposed determination with the court, claimants have another 90 days to object. If your property sits in an adjudication area, missing either window can permanently change what you own.

Federal Permits That May Still Apply

A state water right doesn’t automatically let you build whatever infrastructure the project needs. If construction involves placing fill material in navigable waters or wetlands, you may also need a Section 404 permit from the U.S. Army Corps of Engineers under the Clean Water Act. That covers dams, dikes, intake pipes, and even temporary structures like cofferdams.⁸

If your diversion crosses federal public land managed by the Bureau of Land Management or the U.S. Forest Service, you’ll likely need a right-of-way permit from the relevant agency. Utah has substantial federal land holdings, so this comes up more often than in most states. A state water right and a federal land-use authorization are independent requirements, and holding one does not satisfy the other.
