The record and the river

Where this structure is measured

GageFlowing nowRecordHow we know
PLEASANT VALLEY LAKE CNL PVLCANCO 22.25 cfs 2015–2026, 3,919 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

22.25 cfs as of 2026-10-13 10:45 (2.3 h ago)

Provisional 15-minute telemetry from PVLCANCO ↗ (PLEASANT VALLEY LAKE CNL). 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

PLEASANT VALLEY LAKE CNL holds 28 decreed rights on CACHE LA POUDRE RIVER. A call at CANAL 3 DITCH on CACHE LA POUDRE RIVER (1870-04-01), and 2 others currently reaches it: junior rights called out. 1 further call state no district and sit outside this one, so it is counted here rather than assumed either way. That is today's position; the weeks ahead cannot be projected for it: no administrative call record for this basin. In a median year over its last 15 recorded years it diverts 10,812 acre-feet. It was a party to 1 court cases that also touched 2 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.

Which of its rights are out of priority?

The outlook for the weeks ahead is not computable for this structure: no administrative call record for this basin. 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 1861-06-01 — 5th most senior of the 2964 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: GREELEY FILTERS PIPELINE (1861-06-01). Immediately behind: LARIMER COUNTY DITCH (1861-06-01).

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 (28)

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 137.93 cfs decreed rate, the average day over the last 6 year(s) had 137.93 cfs in priority (100% of the decree). No call in effect is a free river — that was 100.0% of days.

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: 0.

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 10,812 AF. Its most recent year on record, 2024, came in at 10,989 AF — 102% of that, and 10th lowest of the 15 years with a recorded volume.

This structure records both diversions and reservoir releases — they are separate water movements and are accounted separately below.
