GageFlowing nowRecordHow we know
CROKE CANAL 0700553A — 2025–2026, 319 days DWR telemetry mapping
CLEAR CREEK AT CROKE CANAL DIVERSION CLECROCO — 2019–2019, 141 days co-located, 12 m

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.

In short

CROKE CANAL holds 78 decreed rights on CLEAR CREEK. No call currently reaches it that we can lawfully attribute, so none of its rights are being curtailed by one. 7 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 10,305 acre-feet. It was a party to 52 court cases that also touched 46 other structures.

Assembled from the figures on this page — every number above is checked against them before it is shown (6 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 (19 active call(s) checked).

7 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 (19 active call(s) checked), so none of its 78 rights is administratively curtailed today. (7 call(s) state no district and sit outside this one — not judged, not assumed.) In the 5 past years most like this one (2016, 2018, 2020, 2021, 2017), 3 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 ROCKY MOUNTAIN DITCH around 2026-10-01 (the newest reading on file) — currently 103% 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 1860-02-25 — 5th most senior of the 1815 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: CLEAR CR PLATTE RIVER D (1860-02-25). Immediately behind: FARMERS HIGHLINE CANAL (1860-02-25).

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 (82)

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 1132.658 cfs decreed rate, the average day over the last 6 year(s) had 566.345 cfs in priority (50% of the decree). No call in effect is a free river — that was 4.6% of days.

On 1726 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. A call began or ended mid-day on 18 of these days.

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 →

Checked against DWR's own analysis

DWR publishes a day-by-day out-of-priority analysis for some rights. Where it exists we score this page against it — computed live, so it reflects what the code does right now, not what a memo once said. Agreement on this structure: 94.1% on whether a day was curtailed, and 83.2% of days land on DWR's exact percent of the day.

Right (admin no)DWR'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.Days compared AgreementDays matching DWR's exact % Mean errorDWR: days curtailedThis page

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: 4358, of which 3875 sit on a river it flows into.

Filings that would move water above this headgate

1 water-court application in the monthly resumes names a structure on CLEAR CREEK upstream of this headgate. A new right, exchange or change of use up there changes what arrives down here — the resume is the public notice, and the opposition window is how anyone affected answers it.

Judged on this structure’s own named stream only — a filing on a tributary that joins upstream is not judged here. Filings that name structures only in prose, without a WDID, are invisible to this card. Reading aid, not legal advice; the deadline is computed from C.R.S. 37-92-302(3), and the court’s own notice controls.

Water-court filings naming this structure

1 application in the monthly water-court resumes explicitly reference this WDID. The resume is the earliest public notice of a new claim (C.R.S. 37-92-302) — years before anything reaches the decree record below. Most applications name structures by name rather than WDID, so absence here is weak evidence of absence.

How often is it out of priority?

Across the 11 seasons whose call record is complete enough to judge this structure (2016, 2017, 2018, 2019, 2020, 2021, 2022, 2023, 2024, 2025, 2026), week by week from April.

Snow sets the clock here. In the driest third of snow years (3 seasons), the call was on all season, every season. In the middle third (5 seasons), the call settled in for the season around May 27; in 4 of them it never lifted at all. In the wettest third (3 seasons), the call settled in for the season around June 24 (June 17 to July 8 across those years).

Snow years ranked by the district’s April 1 snow-water percentile across 1 SNOTEL site; 11 seasons carry both a snow reading and a judgeable call record. How the past played out, not a forecast.

Why only 11 seasons, and what the bars mean

Each bar is one week: how many of those seasons that right was out of priority under a call this site can lawfully attribute to this structure. Green is never, red is every season on record.

The short record is a property of DWR's data, not of the river. A call only counts against a structure when we can establish it applies — by the districts named in its set comments, or by stream mile on the same source. DWR did not begin stating affected districts routinely until about 2015: fewer than one call in ten can be judged before then, against roughly two in three since. A season we cannot judge is not a season without calls, so it is dropped rather than counted as quiet — 12 seasons dropped here.

This is a frequency over past seasons, not a forecast. It says nothing about what the division engineer will do this year.

DWR’s own out-of-priority analysis

The Division of Water Resources computes its own daily priority analysis for this structure (analysisservices/callanalysisbywdid) — the authoritative answer to “could this right legally divert that day”, from the agency that administers the river. Shown beside, never blended into, the climatology above: different method, different span, and you should know whose number is whose.

Right (admin no.)Span analyzedDays Mean % of day out of priorityDays effectively curtailed
3708.00000 2021-01-01 → 2025-12-31 2,300 0.0% 0.0% (≥50% of the day)
61358.00000 2021-01-01 → 2025-12-31 2,300 65.3% 66.3% (≥50% of the day)

DWR’s series is cached for a scoped set of structures (the rights that move the most water, bracketed most-senior and most-junior) — absence of a right here means it isn’t in that set yet, not that it is never curtailed.

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 10,305 AF. Its most recent year on record, 2025, came in at 9,093 AF — 88% of that, and 6th lowest of the 15 years with a recorded volume.
