TREASURE PASS D

Structure dossier · WDID 2000921 · DITCH · TRANSBASIN WATER · DWR record

Treasure Pass D is a ditch on Transbasin Water 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 16:22 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.

This is water crossing the divide

Treasure Pass D is the receiving end of the Treasure Pass Ditch (ditch). It takes water from Wolf Creek, San Juan basin at Wolf Creek Pass (Div 7) and delivers it to Rio Grande basin (Div 3). Water arriving here is an import: it was never in this basin’s own runoff.

The other end: Treasure Pass Divr Ditch 2904669

Metered as a facility: TREDITCO — 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
TREASURE PASS DITCH AT WOLF CREEK PASS TREDITCO 2.43 cfs 1948–2026, 23,089 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.

Provisional 15-minute telemetry from TREDITCO ↗ (TREASURE PASS DITCH AT WOLF CREEK PASS). 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

In a median year over its last 15 recorded years it diverts 261 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 261 AF. Its most recent year on record, 2025, came in at 267 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.
