In short
SISSON & STUBBS DITCH 1 holds 1 decreed right on ARKANSAS RIVER. As of 2026-09-27, 1 of them are out of priority under a call at admin 20186.17015 placed by JOHN MARTIN RESERVOIR. 14 further calls state no district and sit outside this one, so they are counted here rather than assumed either way. It was a party to 3 court cases that also touched 5 other structures.
Assembled from the figures on this page — every number above is checked against them before it is shown (8 checked). The detail, with its method, is in the cards below.

Current administration
● Fully called out — call at JOHN MARTIN RESERVOIR (ARKANSAS RIVER, priority 1905-04-07).
Which of its rights are out of priority?
Under today's controlling call (JOHN MARTIN RESERVOIR, priority 1905-04-07): 1 of this structure's 1 rights are out of priority now. (14 call(s) state no district and sit outside this one — not judged, not assumed.) In the 5 past years most like this one (2009, 2006, 2022, 2023, 2011), 1 of the rights shown below were out at least one week in at least one analog year.
| Right (priority) | Now | Analog years out | Majority out by |

How this table is built, and what it is not
“Now” compares each right's admin number with today's most senior applicable active call. The outlook uses flows at ARKANSAS RIVER NEAR GRANADA, CO. around 2026-09-27 (the newest reading on file) — currently 79% of that gage's own median for this window — to pick the 5 most similar past years with complete administration records (2005–2026). Only calls that verifiably apply count: DWR's own district statements in the call's set comments, a caller located in this district, or — on the same stream, where DWR records both stream miles (measured from the mouth) — a caller DOWNSTREAM of this structure. An upstream senior cannot demand water this diversion never deprives it of. Calls that state nothing and sit elsewhere are counted as unjudged rather than assumed, which also means the verified record is shorter than the raw one: early calls rarely state districts. For each week it finds the most senior call then in force; a right is out in that week exactly when that call is senior to it, which is why one line prices every right and juniors can be out while seniors keep diverting. “Majority out by” is the first week out in more than half the analog years. A frequency among named historical years, not a probability from a model, and not a forecast of what the division engineer will do. It says how often years whose flow resembled this one were under a call senior to this right in a given week. Snowpack, storage, and the actual administrative decisions of a given season are not modelled. Check the analog years listed: if they do not resemble this year to you, the outlook does not either.
Where it sits in line
Priority 1891-12-01 — 80th most senior of the 2116 structures with decreed rights in this water districtDWR's administrative subdivision of a river basin; the unit calls are usually stated in..
Under prior appropriationColorado's rule for sharing water: first in time, first in right. Age decides, not proximity or need., everything ahead of it in this line is satisfied in full before it receives any water. Immediately ahead: KOEHN WELL (1905-12-31). Immediately behind: SISSON & STUBBS 1 ALT PT (1891-12-01).

Position on the modelled network, not a claim about whose water this is — a stream carries water from many rights at once, and diverted water returns to it.
Decreed rights (1)
| Admin noDWR's numeric encoding of a water right's seniority. Smaller is more senior; the integer part counts days from 1849-12-31 to the date that ranks the right. | AppropriatedWhen water was first put to beneficial use. It sets seniority unless a prior adjudication date is later. | AdjudicatedWhen the water court confirmed the right. A use decreed in 1975 was not a decreed use in 1955, however old the appropriation is. | AbsoluteA right actually put to use, as opposed to conditional -- a placeholder for a use not yet made. | ConditionalA right reserving a place in line for a use not yet made; it must be diligently pursued or it lapses. | Alt-pointAn absolute amount decreed at another structure that may be diverted here instead -- an alternate point of diversion or an exchange. DWR calls this the APEX amount; a right showing 0.0 absolute but an alt-point amount is exercised here under another structure's decree. | Decreed forWhat the court said this water may be used for -- irrigation, municipal supply, augmentation and so on. | Case |
|---|---|---|---|---|---|---|---|
| 20570.15310 | 1891-12-01 | 1909-11-04 | 7.0 cfs | 0.0 | — | Irrigation, Augmentation | 19 |
Amounts marked cfs are flow rates; AF are stored volumes (storage rights are decreed in acre-feet). An absolute amount of 0.0 beside an alt-point amount is not a dead right: the water is decreed at another structure, and that row records permission to divert it here instead (an alternate point or exchange). A case listing several numbers reflects the original decree plus later change cases.
How much of this decree was in priority, by day
A right is in priority on a day when it is senior to every call administering this structure. Of its 7.0 cfs decreed rate, the average day over the last 6 year(s) had 2.315 cfs in priority (33% of the decree). No call in effect is a free river — that was 0.0% of days.
On 8 days some rights were in priority and others were not — seniority splits a decree rather than switching it off. Calls are set and released at a time of day, not at midnight, so a day is counted by the hour: a call setting at 4pm costs that day a third of its rate, not all of it.
This is paper water. It is the decreed rate that was in priority — not water that was physically in the stream, and not water this structure diverted. A ditch can be in priority for 50 cfs on a day the creek carries five. What that distinction means →

How this is worked out, and what it cannot tell you
- This is a decreed rate that was in priority -- paper water, not water that was available or diverted.
- Augmentation plans, exchanges and substitute supply plans let a structure divert lawfully while out of priority; none are modelled.
- Calls on the river this source flows into are included without a position test, so curtailment can be over-reported where the calling point sits above the confluence.
- DWR's administration is the authority. Scored against DWR's own call analysis, this method agreed on 95.5% of 85,822 structure-days (2026-08-29).
- Calls considered for this structure: 1867.

Structures it shares court cases with
This structure was a party to 3 court cases that also touched 5 other structures — changes of water right, augmentation plans, exchanges. Being parties to the same case does not by itself mean water moved between them; which way it ran, and how much, is in the decree.

How this is derived
Every court action DWR records for a structure
carries its case number. Where one case number appears in the records of
several structures, those structures were parties to the same proceeding.
This is read straight from the cached transaction tables — no
document was interpreted to build it. Case numbers are validated against
the known Colorado formats first: the case column also contains stray
dates (10/04/1884 appears on 98 Clear Creek rows), and
treating one as a case number would invent a shared proceeding between
60 unrelated structures. Cases spanning more than
12 structures are separated out as omnibus
adjudications. The filing year comes from the case number, not from the
row's adjudication date — that date belongs to the water right the
action describes, so a 2006 case legitimately carries a 1989 date.
Recorded use (last 15 years on record)
Years far under the decreed amount? That gap has a name — paper water vs. wet water, explained on this structure.
In a median year this structure has a recorded diversion of 0 AF. Its most recent year on record, 1982, came in at 0 AF — —% of that, and 1st lowest of the 13 years with a recorded volume.
This structure records both diversions and reservoir releases — they are separate water movements and are accounted separately below.
| Year | Diverted (AFA volume: one acre covered a foot deep, about 326,000 gallons -- roughly a suburban household's outdoor use for a year.) | Compared with its own record | Released (AF) | Days recorded | Peak (cfs) |

Trends for this structure
Recorded use shows no clear trend over its last 13 recorded years — which is itself worth knowing.
Its reference gage, Arkansas River near Granada: no clear flow trend, with a detected shift around 2001.
How good is our record of it?
Grade B (7/10 points) — the components below are the finding; the letter alone is not.
The rubric, component by component
| Check | State | Detail |
|---|---|---|
| identity | complete | name, type, and water source all on file |
| decreed rights | on file | 1 right(s), seniority decoded |
| diversion record | stale | 3128 measured days, but newest is 8763 day(s) before the data's end (target 450) |
| record continuity | sparse | 27% of the irrigation seasons in 1948-2002 carry measured days |
| published-record stability | stable | no upstream revisions recorded against this structure |
