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 right is a right to store, and the right of beneficial use is held by the beneficial users. That determination, and the storage figures behind it, are set out on the Water Rights and Contracts page.

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 govern the District's operations — KA-1001 (Van Brimmer, 1883), KA-1004 (Ankeny-Henley, 1884) and KA-1000 (the Klamath Project, 1905) — and their priority dates, rates, duties, seasons, diversion caps and ownership are set out on the District's Water Rights and Contracts page.

What matters here is that every Warren Act land in the Project is served under KA-1000, on that 1905 priority date, alongside everyone else. There is no separate, later-dated Warren Act right, because the State declined to create one.

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.

That sentence has an affirmative half as well as a disclaimer, and the District's reading of what “all reasonable means to guard against it” requires — of storage, and of what the United States proposes in Endangered Species Act consultation — is set out on the Water Rights and Contracts page.

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 the Company's own adjudicated 1883 right, 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 dedication program puts the appropriation at $934,000 and the actual construction cost at $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

The Commissioner of Reclamation reported in April 1962 that about 84,000 acres of the 217,000 acres in the Klamath Project were served pursuant to the Warren Act — roughly two acres in every five. Warren Act service was never a marginal thing at the edges of this Project.

In a short year

Warren Act lands hold the same 1905 Project priority as everyone else. What ranks them is their contracts, which begin in 1918 and carry the 1911 statute's reservation of a first right to the lands and entrymen already under the Project. That subordination is contractual, and in a dry year it is real.

In 2026 it showed up as a number. Reclamation limited Warren Act contractors to 0.75 acre-feet per irrigable acre and provided no water at all to rental contractors.

How the District fills orders in a short year, what its 1954 contract does and does not authorize, the Oregon statutes that govern distribution, and the District's July 1, 2026 response to those letters are all set out on the Water Rights and Contracts page.
