Your Tumalo Water Right Is a Legal Claim, Not a Delivery Guarantee

A water right on a Tumalo property deed reads like a promise. It has a certificate number, a priority date, an acreage figure, language calling it appurtenant to the land. Buyers see that language and treat it the way they'd treat a paid-off mortgage: settled, permanent, done.

This summer showed that isn't quite how it works. A Tumalo landowner with fully deeded water rights had his irrigation water shut off completely in June, according to KTVZ reporting on the district's ongoing shortage. The rights were real. The water wasn't there. If you're buying or selling acreage in Tumalo Irrigation District's service area, that gap between what the deed says and what actually reaches the headgate is the thing worth understanding before you sign anything.

The District Is Having One of Its Worst Years on Record

Tumalo Irrigation District pulls its water from Tumalo Creek and from storage at Crescent Lake, and 2026 has been rough on both. Regional reporting through the spring and early summer put the district's deliveries at somewhere between 60 and 70 percent of a typical year's supply. The timing was as much a problem as the volume. General manager Chris Schull told the Bulletin the district had to start drawing down Crescent Lake storage two months earlier than usual. Crescent Lake held about 20,147 acre-feet on July 1. By August 14 it was down to roughly 12,899 acre-feet, a drop of about 36 percent in six weeks, with almost no natural inflow refilling it in that stretch.

Schull has been managing TID long enough to have context for this. He's pointed to prior water-short years in 1992, 1994, 2004, and 2005 as the district's historical low points. What makes 2026 different, by his account, is the combination of limited storage, early runoff, and a fast drawdown of what was left. The district moved its own water-start date up to April 1 for this season and had already scheduled a season-ending shutoff for August 31, the same date this post is being written. Rotation 1 patrons on the piped portion of the system lost water a week earlier than that, on August 24.

Here's how the two reservoirs that matter most to Central Oregon irrigation compared to a year ago:

Wickiup serves other Deschutes Basin districts more directly than it serves TID, but the year-over-year gap gives a sense of how widespread the shortfall is across the region TID sits inside.

Why the Same District Cuts Some Patrons Deeper Than Others

Not every TID water right is equally protected in a short year, and this is the detail that rarely comes up in a listing conversation. TID's own water rights carry priority dates ranging from 1900 to 1913. Under Oregon's prior appropriation system, older priority dates get served before newer ones when supply runs short. According to the district's own water user handbook, most TID patrons actually hold a 1913 supplemental right rather than the more senior 1900 through 1907 primary rights, because the earliest allocations were limited in scope.

That distinction matters at the property level. A parcel's specific certificate, not just the fact that "the property has water rights," determines where it sits in the rotation when the district has to ration. A buyer comparing two similar-looking Tumalo parcels with water rights attached should ask which priority date and which rotation group each one carries, not just whether the box marked "water rights included" is checked on the listing sheet.

What Actually Happens When Water Rights Change Hands

Water rights in TID's system are appurtenant, meaning they're legally tied to specific acreage, not to the person who owns it. Moving a water right from one parcel to another, even between two properties owned by the same person, requires a formal transfer through the district. TID's own process for a permanent transfer under state water law includes several steps that a buyer or seller should build into a closing timeline rather than discover partway through one:

1. The district requests a title search on the property to confirm ownership and notify any lienholders, unless the transfer is self-to-self.
2. District staff or an outside Certified Water Rights Examiner maps the water off the old parcel and onto the new one.
3. Both parties sign a packet that includes a Notice of District Permanent Transfer, a purchase agreement for the water, and an affidavit confirming the right hasn't been abandoned.
4. The new location has to be proved up, meaning the water actually gets put to beneficial use there, by the end of the same irrigation season.

That last step is the one that catches people off guard. If proving up doesn't happen by season's end, the district won't include the transfer in its December petition, the transfer fees aren't refunded, and the water stays put on the original parcel until someone resubmits and pays again the following year. In a season like 2026, where the district cut deliveries and ended early, that prove-up window closes faster than a typical transfer timeline assumes.

The Ditch Behind the Barn Might Not Stay a Ditch

There's a second piece of transaction friction that has nothing to do with drought and everything to do with infrastructure. TID has spent more than two decades converting open canals and laterals to buried pipe, both to cut seepage and evaporation losses and to reduce the safety risk open water poses along a property line. A group of landowners sued the district over piping installations that removed canals on their private land, and in December 2024 the Ninth Circuit Court of Appeals sided with TID, confirming the district's right to continue the conversions through its easements even where a landowner objects.

At the time of that ruling, TID's manager estimated 40 to 44 percent of the district was still running through open canal. The district's most recent piping update on record noted no piping work during the 2025 into 2026 maintenance season, so a property fronting open water hasn't necessarily seen construction yet. But the modernization project is a multi-year effort, and TID's own rules prohibit replanting trees within 25 feet of a buried pipeline once it's installed. A buyer who values the look of an open ditch along a pasture edge, or who's planning tree cover near that ditch, should ask the district directly whether that stretch is on a future piping schedule rather than assume the current view is permanent.

Questions Worth Asking Before You Write an Offer

A few questions turn "the property has water rights" from a marketing line into something you can actually evaluate:

• What is the priority date on this specific certificate, and which TID rotation group does the parcel fall into?
• Has the water right been used beneficially within the last five years, as TID's rules require, or is there a lapse that could complicate a future transfer?
• Is the irrigation ditch or lateral serving this parcel open canal or already piped, and is it on TID's future conversion schedule?
• If a transfer is part of the deal, does the closing timeline allow for the prove-up requirement to be met before the current irrigation season ends?
• Does the parcel sit inside TID's boundary at all, or does it draw from a different local system, since not every Tumalo property is served the same way?

None of these questions show up on a standard disclosure form. They come from knowing the district, its history, and what a season like this one actually does to the rights on paper.

Water rights are still a real asset in Tumalo, and in a normal year they function the way the deed language suggests. But 2026 wasn't a normal year, and the properties that came through it with full deliveries weren't necessarily the ones with the most acreage of water right on paper. They were the ones with the earlier priority date, the better rotation slot, and an owner who understood the difference well before closing day.

If you're evaluating a Tumalo property with water rights attached, or preparing one for sale, it's worth working through these specifics before an offer gets written rather than after.
