CAMERON PASS DITCH RELEASE STRUCTURE

Structure dossier · WDID 0304602 · OTHER · JOE WRIGHT CREEK · DWR record

Cameron Pass Ditch Release Structure is a water structure on Joe Wright 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 07:17 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.

The record and the river

This is water crossing the divide

Cameron Pass Ditch Release Structure is the receiving end of the Cameron Pass Ditch (ditch). It takes water from North Platte basin at Cameron Pass (Div 6) and delivers it to Joe Wright Creek, Cache la Poudre (Div 1). Water arriving here is an import: it was never in this basin’s own runoff.

The other end: Cameron Pass Ditch 4704602

Metered as a facility: CAPDCPCO — the record for the crossing itself, which may run longer than the record for either structure.

Where this structure is measured

GageFlowing nowRecordHow we know
CAMERON PASS DITCH NEAR CAMERON PASS CAPDCPCO — 1931–2026, 33,325 days DWR telemetry mapping
CAMERON PASS DITCH RELEASE STRUCTURE 0304602A — — named for this WDID

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

In a median year over its last 14 recorded years it diverts 92 acre-feet.

Assembled from the figures on this page — every number above is checked against them before it is shown (2 checked). The detail, with its method, is in the cards below.

What is in the bundle
  • rights.csv — every decreed right, most senior first, with admin numbers, dates, amounts, uses and case numbers.
  • annual_use.csv — recorded diversion by year, with releases accounted separately.
  • curtailment_now.csv — each right's current priority status and how often it was out across analog years.
  • court_cases.csv — the cases attached to its rights.
  • co_parties.csv — the other structures that were parties to those cases. Not available anywhere else.
  • call_climatology.csv — how often each right has been out of priority by week of season, with confidence intervals and the seasons the record could actually judge.
  • README.txt — provenance, methods, limits, disclaimer, and links back to DWR's own records for verification.

Which of its rights are out of priority?

The outlook for the weeks ahead is not computable for this structure: no decreed right on file, so there is no priority to test.

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 92 AF. Its most recent year on record, 2025, came in at 0 AF — 0% of that, and 1st lowest of the 14 years with a recorded volume.

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

How good is our record of it?

Grade C (5/10 points) — the components below are the finding; the letter alone is not.
