Chilcott Ditch is a ditch on Fountain Creek in Colorado. This page is its public record: the water it has a right to, whether it may take it today, and its history, compiled from the Colorado Division of Water Resources.

Where this page's figures come from

Generated 2026-10-14 21:31 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

  • Chilcott Ditch Company (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 Monument; 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DWR’s own records name no owner for a ditch, reservoir or well, so this comes from the source shown and can be out of date.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.

Where this structure is measured

GageFlowing nowRecordHow we know
CHILCOTT DITCH NEAR FOUNTAIN, CO CHIDITCO 4.3 cfs 2005–2026, 7,573 days DWR telemetry mapping

A green link is DWR's own: either its telemetry inventory maps this WDID to that station, or the station is named for this WDID (0700553 → 0700553A). An amber one is ours — the station sits within 250 m and shares a distinctive word with this structure's name, which is a strong hint rather than a DWR statement that this gage meters this structure. Wrong? Tell us.

Flowing now

4.3 cfs as of 2026-10-14 21:15 (0.3 h ago)

Provisional 15-minute telemetry from CHIDITCO ↗ (CHILCOTT DITCH NEAR FOUNTAIN, CO). Raw, not the approved record — it is never merged into the diversion history below. DWR publishes the official diversion record after the water year closes and is approved, which is why that record ends months back while this reads minutes ago.

In short

CHILCOTT DITCH holds 11 decreed rights on FOUNTAIN CREEK. No call currently reaches it that we can lawfully attribute, so none of its rights are being curtailed by one. 14 further calls state no district and sit outside this one, so they are counted here rather than assumed either way. In a median year over its last 15 recorded years it diverts 4,427 acre-feet. That use is falling by about 367.0 acre-feet a year over 15 years (p=0.005583616806378755). It was a party to 9 court cases that also touched 11 other structures.

Assembled from the figures on this page — every number above is checked against them before it is shown (9 checked). The detail, with its method, is in the cards below.

Current administration

● In priority — no active call senior to this structure's rights affects its district (20 active call(s) checked).

14 further calls state no district and sit outside this one, so they are counted here rather than assumed either way.

Which of its rights are out of priority?

No active call verifiably reaches this structure (20 active call(s) checked), so none of its 11 rights is administratively curtailed today. (14 call(s) state no district and sit outside this one — not judged, not assumed.) In the 5 past years most like this one (2007, 2006, 2009, 2010, 2016), 0 of the rights shown below were out at least one week in at least one analog year.

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 CRUSE GULCH NEAR FOUNTAIN, CO around 2026-09-27 (the newest reading on file) — currently 181% 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.

Decreed rights (12)

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

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 83.01 cfs decreed rate, the average day over the last 6 year(s) had 77.11 cfs in priority (93% of the decree). No call in effect is a free river — that was 0.0% of days.

On 286 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: 2051, of which 1871 sit on a river it flows into.

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 4,427 AF. Its most recent year on record, 2025, came in at 3,074 AF — 69% of that, and 2nd lowest of the 15 years with a recorded volume.
