What the State of Oregon determined

The Klamath Basin Adjudication is where water rights in this Basin were settled. Its Corrected Partial Order of Determination for OAH Case 003 disposed of the Klamath Project claims, and it addressed the Warren Act contracts head-on.

The order holds that the Warren Act contracts did not separately convey any additional rights to the contractors. Those contracts were entered into under 43 U.S.C. §§ 523–525, by which the United States promised to deliver water in return for a payment and annual fees. Nothing in them transfers a right. The order points to the contracts' own recital: the contractor proposes to irrigate the described acres by utilizing Klamath Project water rights.

So the portions of those claims founded on Warren Act contracts were denied. The lands themselves were not left out in the cold, however. They are entitled to a water right based on the United States' Notice of Appropriation of May 19, 1905, and where they fell within the Project claim they were recognized as part of the place of use for the consolidated Project claim.

That is the answer to the question, from the only body with authority to give it. Warren Act lands sit inside the Project claim on the Project's priority date. Their contracts govern delivery, not priority.

The order also settles who holds what. Reclamation's storage claim, filed on the May 19, 1905 notice, is Claim 294 — a right to store water in Upper Klamath Lake, year around, from tributaries above the lake. The order recognizes it and holds the right to store is held by the United States, denying the water users' competing storage claim. Active storage capacity is put at 486,830 acre-feet, with annual volume in the lake not to exceed 629,870 acre-feet including inactive storage.

But storage is all it is. The order holds that the right of beneficial use of water in the Project is held by the beneficial users, and says so of live flow and stored water alike. The users' claim to appropriate water actively stored in Upper Klamath Lake was recognized inside the Project consolidated claim. Reclamation stores; the users hold the right to use. Those are different things, and the order keeps them apart.

The three claims, as determined

Three adjudicated claims matter to the District's operations. These are the rights. Everything after this section is contract.

And what the District may divert

The order does not stop at a duty. Table A of the Project consolidated claim sets a maximum rate at each measurement station, and those are the caps on this District's own diversions.

KA-1004 has the longest history of the three, and the order sets it out. A ditch begun in 1878 was conveyed in 1882 to the Linkville Water Ditch Company. William Steele enlarged it in 1884 — six feet on the bottom, extended fifteen and a half miles into the Klamath valley, enough to irrigate about sixteen thousand acres. It passed to the Big Klamath Ditch Company, then on Steele's death to his widow Esther, who in 1891 sold one-sixth interests to two of her children. By the turn of the century Mr. Ankeny, Mr. Cantrall and Mrs. Henley were its sole owners, and the canal had become known as the Ankeny-Henley, or Steele-Ankeny, Canal — sixteen to twenty feet wide at the bottom, carrying about fifty cubic feet per second. In July 1906 the Klamath Falls Irrigation Company sold the Ankeny-Henley Canal and all water rights in it to the United States. The State found the evidence supported a right for 49 cfs with an 1884 priority, and that is what KA-1004 is.

Every Warren Act land in the Project is served under that last claim, on that 1905 priority date, alongside everyone else. There is no separate, later-dated Warren Act right, because the State declined to create one.

Poe Valley is worth a word, because it is the clearest case of the two documents saying different things. Its contract draws on the Lost River and delivers below Harpold Dam. Its water right is something else: Poe Valley Improvement District is a named claimant on this consolidated Project claim, alongside the District and the rest of the Project water users, whose adjudicated sources are the live flow of Upper Klamath Lake and the water stored in it. The adjudication did not confine Poe Valley to the Lost River. Its contract did.

What the District agreed to carry

In 1954 the District signed the transferred-works contract with the United States and, on January 1, 1955, took over care, operation and maintenance of the Project's canals, drains and pumps. (The history pages carry the longer account of how the Project was built and how the District came to operate it.) It also took on the United States' delivery obligations to others. Those obligations are spread across several articles.

Article 26 adds what everyone in this Basin already knows: on account of drought or other causes a shortage may occur, the United States will use all reasonable means to guard against it, and no liability accrues against the United States for the damage when it comes.

The disclaimer at the end of that sentence gets quoted often. The duty at the front of it gets quoted rarely, and it is the more consequential half. All reasonable means to guard against it is an obligation to act. In the District's reading it carries at least two consequences.

It means storing water. The means of guarding against a shortage in this Project is the storage right the United States holds under Claim 294, and the adjudication says what that right is held for: to benefit the separate irrigation rights recognized for the Klamath Reclamation Project. A duty to use all reasonable means to guard against shortage is a duty to exercise that storage right toward the purpose it was recognized for.

And it means what the United States proposes when it consults. Under the Endangered Species Act the action agency proposes an action; the consulting agencies evaluate that action; and a reasonable and prudent alternative is what a biological opinion supplies if the proposed action is found to jeopardize a listed species. An alternative is a remedy applied to a proposal. It is not the proposal. The District's position is that Article 26 requires the United States to propose an action that makes full contract deliveries and to let the consultation test that action — rather than to propose reduced deliveries at the outset, which settles the question before any biological opinion is written.

Who the District actually serves

Those articles are not abstractions. Water moves through this District's works to its own patrons and to nine others, and each one arrives by a different door — most by carriage through the canals, one by the District's spill into the Lost River.

Not every district in the Basin is on that list. Klamath Drainage District, Horsefly and Langell Valley are Klamath Project districts, but they are not served through this District's works.

Where the delivery order is written

The adjudication settled priority. The contracts settled the order of delivery, and three of them say it outright.

Tulelake's 1956 contract states that the District's rights are equal to those of others contracting under the Reclamation Act of 1902, and prior to rights conferred under contracts executed under the Warren Act. It adds that where a shortage arises from drought or other unavoidable causes, the United States may apportion the available supply among those holding rights of priority equal to Tulelake's.

That second sentence needs care, because it is easy to read as though it settled something for everyone. It did not. It is a term of Tulelake's contract, and it binds the parties to Tulelake's contract. This District's 1954 contract contains no apportionment provision at all. The words allocation and apportionment appear in it only in relation to money — the general expense apportioned between the Main and Pumping Divisions under Article 16, and the reserved-works costs allocated between the District and other agencies. Nothing in the District's contract provides for apportioning water, and the District agreed to no such term.

Van Brimmer's contracts show the same ordering from the other side, and they are worth separating carefully, because the Company holds two different things under two different kinds of instrument.

The contract of November 6, 1909 is a settlement agreement, not a Warren Act contract. The Project was going to lower Lower Klamath Lake and, in the contract's own words, would in all probability destroy or impair the Company's source of supply at its own diversion point. The Company waived and renounced its riparian claims to the United States; the United States undertook to deliver fifty second-feet from the Project in their place. That fifty second-feet is settled entitlement, and the State later adjudicated it as the Company's own right with an 1883 priority.

Water above the fifty second-feet is a different arrangement, and a different piece of plumbing. The settled fifty comes from Upper Klamath Lake and reaches the Company by gravity through the Project canals; the Lost River cannot deliver to those lands by gravity at all. Water above that figure would be pumped from the Lost River — into which the District spills — on terms that behave like a Warren Act contract. Under the amendatory contract of February 3, 1943, such water is paid for by the acre-foot, and the United States is not obligated to deliver any of it when the excess is needed for the Project lands or for the Warren Act contractors, whether those contracts predate or postdate 1943.

In practice that provision is dormant. The District does not typically deliver above fifty second-feet, and does not anticipate doing so in the foreseeable future. What the Company receives is the settled entitlement, delivered as it has been delivered since 1955.

Which explains the entry that looks odd at first glance. The District's 1954 Exhibit “A” is headed Warren Act Contractors Entitled to Water from Distribution System, and Van Brimmer is on it — recorded not in acres, like every other entry, but with two words: Excess Only. The Company is on that sheet for its excess and for nothing else. The settled fifty second-feet was never a Warren Act matter: it is an adjudicated 1883 right, held in trust by the District, and served under Article 13(a) as water delivered to a user entitled to it. Only the excess sits under Article 13(b).

The District's own Article 19 puts rental water below everyone.

What each contract actually promises

This is where the difference between a right and a contract stops being abstract. The two Reclamation Act contracts name no quantity at all. The Warren Act contracts name one — and define what kind of water it is.

The Klamath Basin Improvement District contract is the one worth reading twice, because the article above it defines the term the promise turns on.

So the 3.6 acre-feet is not a duty and not an entitlement. It is a ceiling on water that has already been defined as whatever is left after the prior rights of the Project's lands and entrymen are met. The transmittal that accompanied the contract says the same thing in the plainest possible terms: the supply is limited to what is surplus to the needs of the existing Klamath Project, and it is made available under the Act of February 21, 1911 — the Warren Act. The largest figure in the Project's contracts is also the most conditional one, and the condition is written into the definitions.

That phrase — the prior rights of lands and entrymen under the Klamath Project — is the Warren Act's own reservation, carried word for word out of the 1911 statute and into a contract signed fifty-one years later.

And the contractors' own contracts say it too

The subordination does not have to be inferred from Tulelake's contract, or from the District's, or from anyone else's. It is written into the Warren Act contracts themselves, in the contractors' own instruments.

The Shasta View and Malin contracts of 1922 provide that the rights to the use and delivery of water acquired by the District under the contract are inferior and subject to prior rights reserved for the lands of the Klamath Project. Poe Valley's 1953 contract puts it as an affirmative reservation at Article 2: the United States reserves a first right to the lands and entrymen on the Klamath Project of the water to be made available to the District. And the Klamath Basin Improvement District contract of 1962 does it by definition, in the passage above.

Four decades apart, three different drafters, the same reservation. It is the Warren Act's phrase in each case — the first right of the lands and entrymen already under the Project — and every contractor signed it.

The same contract also says what happens when the surplus runs short. Article 4 provides that on account of drought, inaccuracy in distribution, or other cause there may be a shortage, that no liability accrues against the United States for it, and that in any year in which a shortage occurs from any cause, the United States reserves the right to apportion the available surplus water supply among the District and others entitled, under existing and future Warren Act contracts, to receive water from the Klamath Project. Apportionment among the Warren Act contractors — not among all Project lands, and not ahead of them.

Pine Grove is the only one of these that changed. Every district contract on the list began at two acre-feet; Pine Grove asked for more and got it in 1936, which is why a single district sits half an acre-foot above the rest.

Article 13(c), in practice

The Klamath Basin Improvement District contract is also the clearest surviving demonstration of how Article 13(c) actually operates, because the 1962 file shows the whole machine assembled at once.

The contract's recitals state the problem plainly: delivery of surplus Project water to the District's lands depended on enlarging and extending certain Klamath Project facilities — facilities now operated and maintained by the Klamath Irrigation District under Contract No. 14-06-200-3784 of November 29, 1954, which the KBID contract refers to throughout as the Operations Contract. The District's 1954 contract is named in it, by number and by date, as the instrument the whole arrangement rests on.

From there the sequencing follows Article 13(c) exactly. No federal funds could be advanced until two things had happened: a contract between Klamath Basin Improvement District and Klamath Irrigation District under which the latter agreed to care for, operate and maintain the Project Works and to deliver the water; and a contract between Klamath Irrigation District and the United States amending the Operations Contract to permit the construction and provide for the care, operation and maintenance of the works. Three contracts, executed together in April 1962: the United States with KBID, the United States with this District, and this District with KBID.

Note what that arrangement respects. Article 13(c) permits future carriage-and-delivery contracts, but bars any that would require additions to or enlargements of the transferred works unless the United States or the contractors bear the expense. Here the contractor did — Klamath Basin Improvement District borrowed for the enlargement under the Small Reclamation Projects Act of 1956 and repays it. The proviso in the District's 1954 contract was not waived. It was satisfied.

And what it built

The third of those contracts was executed. On April 25, 1962, Klamath Basin Improvement District and Klamath Irrigation District signed an agreement under which this District would operate and maintain the Extensions and carry out the administrative functions of the new district. The arrangement was a close one. Klamath Basin Improvement District had become a legal entity on July 18, 1961, on articles of incorporation signed by 464 landowners, and by 1963 its secretary-treasurer kept his office at the K.I.D. office. It had also executed individual water service contracts with Pine Grove, Enterprise, Shasta View and Malin, each of which had Klamath Basin Improvement District lands inside its boundaries.

What the loan built was dedicated on August 9, 1963, at a ceremony this District co-sponsored: the Stukel, North Poe Valley and South Poe Valley Pumping Plants, enlargement of the Miller Hill Pumping Plant and of portions of the existing D, F and G Canals, and extensions to some drains. The Commissioner of Reclamation and the congressman for Oregon's second district both spoke. The appropriation was $934,000 and the actual construction cost $818,950, repayable over forty years beginning January 1, 1964 — the first loan in Oregon under the Small Reclamation Projects Act.

The dedication summary puts the district's requirement at 30,000 acre-feet a year across 9,238 irrigable acres, of which 10,000 acre-feet would come from existing supplies and return flows and 20,000 from the new works. Sixty percent of the land had been irrigated under temporary arrangements; the rest was dry. And it gives the source in a single line: existing Project storage in Upper Klamath Lake, which it calls more than adequate for this and other possible additions.

How much of the Project this is

Acreage figures for the Klamath Project circulate freely and rarely with a date attached, which makes them look like they disagree when mostly they are measuring different things at different times. Here are the ones this page relies on, each with the document it came from.

Sixty-four years separate the first of those figures from the last. None of them is a substitute for another, and the page does not treat them as interchangeable.

How it works in a short year

Start with what the District controls. Seniority governs the order in which orders are filled, and the two pre-Project rights sit at the top of the list — but seniority sets priority, not exemption. Nobody is guaranteed water to the end of their season, because the season now ends when the supply does.

The 221,000 acre-feet Reclamation made available for 2026 is not a priority determination and does not follow the priority dates. It is a cap on the whole Project, set under the biological opinions, and it runs out on a date of its own. A senior right whose adjudicated season runs to October 31 does not get water to October 31 by virtue of being senior. It gets served first for as long as there is anything to serve.

How the District actually fills orders

The District's Water Delivery Policy and its published operating rules set out how this works in practice. Orders are placed with a ditch rider or through the web system on twenty-four hours' notice, run a minimum twelve-hour set, and are capped at eight days so that water moves through a wait list faster when demand rises. When more water is ordered than can be delivered, a wait list forms — managed by ride, which is to say by ditch-rider division.

Seniority sets priority on that list. It does not exempt anyone from it.

So the order of service tracks the adjudicated priority dates, not the contracts — 1883, then 1884, then 1905, and the Warren Act lands last because their contracts came last. What the District administers is a queue. It does not assign anyone a volumetric share, and it does not move a contract holder up or down that queue by its own judgment.

Its power to stop a delivery outright is narrower still, and confined to two situations: non-payment, or official notice from the Secretary of the Interior.

Put the two halves together and the rest of the dry-year picture follows. Every Project land holds the same 1905 priority under the same consolidated claim. What differs is the contract each one signed, and the contracts rank themselves.

Three layers, and the District controls only the middle one

The source. Under Oregon law the question is availability, not permission. A water right is exercised when water is physically there, and it is curtailed when a senior right places a call and the State regulates the source accordingly. Absent a call, water that is available is available for delivery. There is no annual grant to wait for. And this District cannot place a call: regulation between rights on a source is the watermaster's function, carried out in accordance with the users' existing rights of record.

The District's own works. Inside the District the law says something different, and it says it plainly. Distribution of water from irrigation systems or works is under the exclusive control of the irrigation districts, unless the watermaster has been requested by the district to distribute it. And the Board of Directors is directed to establish equitable bylaws, rules and regulations for the administration of the district and for the distribution and use of water among the landowners.

That is what the wait list and the Water Delivery Policy are. They are not improvisation and they are not apportionment. They are the equitable rules the Board is required by statute to establish, applied to works the District has exclusive control over. The State can still intervene at the far end: where water is not used in a beneficial manner and without waste, the County Watermaster can reduce or terminate the District's diversion and delivery. Oregon law also makes it an offense to interfere with a lawfully established headgate, or to use water another is entitled to, or to willfully waste water to another's detriment.

The federal contracts. Before deliveries under the Article 13 contracts stop, the Secretary of the Interior must determine whether the United States can meet its contractual obligations, and then give the District guidance on the rental water contracts under Article 19 and on the Warren Act contracts under Article 13. That determination belongs to the Secretary. Article 13(f) is the channel through which it reaches the District, which is why the District's own correspondence points to that article.

So the District controls the middle layer and neither of the others. It distributes, under rules its Board is required to make and the State can review. It does not regulate the source, and it does not decide when a federal contract stops.

What the contracts do not do is set an annual per-acre number. Each Warren Act contract states its own quantity, agreed between the United States and that district or that landowner — the ceiling of three and six-tenths acre-feet in the Klamath Basin Improvement District contract, and the figures stated in each of the others. Those quantities were negotiated. They were not left to be reset each spring.

And some of the contracts say how a short year is to be handled — each for itself. Article 4 of the Klamath Basin Improvement District contract provides that when a shortage occurs from any cause, the United States may apportion the available surplus water supply among that District and the others entitled under Warren Act contracts. Tulelake's contract provides for apportionment among contracts of equal priority to Tulelake's. Rental water goes first under Article 19. This District's contract provides for none of that. It contains no apportionment clause, and the District agreed to no formula for dividing a short supply.

In 2026, a different thing happened, and it is worth setting out exactly as it arrived.

On April 6, 2026, Reclamation's Klamath Basin Area Office wrote to the Klamath Water Users Association that Project operations for the year would follow the Annual Operations Plan, that Reclamation was required to operate under separate biological opinions issued by the National Marine Fisheries Service and the U.S. Fish and Wildlife Service in 2024, and that it did not anticipate being able to supply a full irrigation water supply for Water Year 2026. Availability from Upper Klamath Lake and the Klamath River was forecast at 221 thousand acre-feet. The letter said coordination with the Association, the Districts and the Drought Response Agency would follow, and that it would include calculations of this availability amongst Klamath Project contractors.

On April 15, 2026, a second letter reached the District. It stated that the current Project water supply was 221,000 acre-feet, that the supply would be insufficient to satisfy the full irrigation demand of the Project, that water from Upper Klamath Lake and the Klamath River for Warren Act contractors is limited to 0.75 acre-feet per irrigable acre, and that no water would be available to water rental contractors in 2026.

Two things about those letters are worth noticing, and both are matters of what the documents say rather than of anyone's motives.

First, no contract provision is cited in either one. The authorities named are the Reclamation Act of 1902, Federal Reclamation Law generally, the Endangered Species Act, the two 2024 biological opinions, and the Annual Operations Plan. Neither letter cites the 1954 contract, or any article of it, or any Warren Act contract. The 0.75 acre-feet per irrigable acre does not appear in any contract; it appears in a letter.

Second, the contracts describe a different route. Reclamation has not pointed to Article 13(f). The District is the one that raises it, in its own correspondence, because 13(f) is the only provision that directs this District to stop delivering under the Article 13 contracts — and it operates on notice from the Secretary that the contracting parties are not entitled to the delivery of irrigation water, for nonpayment of charges due the United States, or for other reasons. It is a provision about entitlement, and it says nothing about acre-feet per acre. And where the contracts do provide a shortage mechanism, it is apportionment within a class — the Warren Act contractors under the Klamath Basin Improvement District contract, contracts of equal priority under Tulelake's — which is close to what the April 6 letter itself described when it promised calculations of availability among Project contractors. A flat per-acre cap imposed on one class is not that, and this District's contract supplies no formula of any kind.

The District has not left that observation on a webpage. By letter of July 1, 2026, copied to the Acting Regional Director and to the Principal Deputy Assistant Secretary for Water and Science, the District asked Reclamation to identify the specific contractual authority it relies on — and asked in particular about the intended role of Article 13(f), which provides for ceasing deliveries under the Warren Act and outside-district contracts upon notification by the Secretary, together with the written delegation of authority for any official below the Secretary to issue such a direction.

What the District is, under its own contract

There is one more thing worth stating plainly, because it is the source of a good deal of confusion about what this District can and cannot do in a dry year.

Article 13(a) provides that the District takes the Project water supply at the headworks and shall distribute the same to the water users entitled thereto. That makes the District a distribution agent. The contract contains no provision authorizing the District to apportion or ration Project water among its patrons, and none authorizing Reclamation to assign the District a per-acre or volumetric share of Project supply.

So when the District operates within a supply figure Reclamation has announced, that is operational cooperation. It is not the District developing a distribution plan, exercising apportionment authority, or agreeing that the Project is entitled to less than a full water supply.

The order of service and the quantity of service are two different questions. The contracts answer both. Only one of them was answered by contract in 2026.

The documents

Every statement on this page comes from one of the following, in this order of authority: the adjudication first, then the contracts.
