Where this page's figures come from
Generated 2026-10-12 06:31 by Hydrohistorian. Sources: DWR HydroBase snapshot HydroBase_CO_20260928 (history) + CDSS REST (current), USGS NWIS cross-checks. Engine v0.5.0 (dd58e60) — every figure regenerates from this named code version and data image.
Who owns it
- Otero Ditch CO. (nonprofit corporation) — probable match, from the Colorado Secretary of State business record ↗; verify before relying on it. A nonprofit corporation of this name, in good standing, with its principal office in Rocky Ford; matched on the name and the location, not confirmed by the company.
DWR’s own records name no owner for a ditch, reservoir or well, so this comes from the source shown and can be out of date. Organisations only: a private landowner’s name is never listed.

Current administration
● Fully called out — call at FORT LYON CANAL (ARKANSAS RIVER, priority 1884-12-03).
● Junior rights called out — call at JOHN MARTIN RESERVOIR (ARKANSAS RIVER, priority 1905-04-07).
Which of its rights are out of priority?
The outlook for the weeks ahead is not computable for this structure: no gage record for this year at this date, so there is nothing to find analogs for. Today’s position is a separate question, and it is answered in Current administration above — that screen reads the district’s active calls and needs no reference gage.
Where it sits in line
Priority 1890-03-03 — 15th most senior of the 1909 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: CROOKED ARROYA DITCH (1890-02-27). Immediately behind: A J ANDERSON DITCH (1891-01-03).
On MAINSTEM at river mile 30.4, it is 68th of 458 down the reach. Immediately upstream: SM SPRING AND POND. Immediately downstream: 1713571.
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 (2)
| 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 |
|---|---|---|---|---|---|---|---|
| 14672.00000 | 1890-03-03 | 1905-04-08 | 123.0 cfs | 0.0 | — | Irrigation | 13 |
| 20186.19390 | 1903-02-02 | 1922-08-30 | 334.92 cfs | 0.0 | — | Irrigation | 62 |
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 457.92 cfs decreed rate, the average day over the last 6 year(s) had 157.092 cfs in priority (34% of the decree). No call in effect is a free river — that was 0.0% of days.
On 89 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
Also a party to 1 omnibus
adjudication
(10CW0004, 20 structures).
Those settled many rights at once and are listed separately: they say
these structures were adjudicated together, not that they deal with
each other.
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 12,440 AF. Its most recent year on record, 2025, came in at 36,502 AF — 293% of that, and 15th lowest of the 15 years with a recorded volume.

Trends for this structure
Recorded use shows no clear trend over its last 15 recorded years — which is itself worth knowing.
Its reference gage, Otero Canal near Fowler: no clear flow trend.
How good is our record of it?
Grade A (10/10 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 | 2 right(s), seniority decoded |
| diversion record | current | 19099 measured days, newest 331 day(s) before the data's end (DWR publishes ~1 year in arrears) |
| record continuity | continuous | 78% of the irrigation seasons in 1911-2025 carry measured days |
| published-record stability | stable | no upstream revisions recorded against this structure |
