WDID 6203532 is a water structure 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 2026-10-30 12:56 by Hydrohistorian. Sources: DWR HydroBase snapshot HydroBase_CO_20260928 (history) + CDSS REST (current), USGS NWIS cross-checks. Engine v0.5.0 (3876149) — every figure regenerates from this named code version and data image.

Who owns it

DWR’s own records name no owner for a ditch, reservoir or well, so this comes from the source shown and can be out of date.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
BLUE MESA RESERVOIR BLMRESCO — — co-located

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

6203532 holds 7 decreed rights. No active call senior to its rights reaches its district today (11 active calls checked), so it is in priority now. 11 further calls state no district and sit outside this one, so they are counted here rather than assumed either way. That is today's position; the weeks ahead cannot be projected for it: this structure is not on the modelled flow network, so no reference gage can honestly stand in for it. In a median year over its last 15 recorded years it diverts 291,672 acre-feet. It was a party to 23 court cases that also touched 57 other structures.

Assembled from the figures on this page — every number above is checked against them before it is shown (8 checked). The detail, with its method, is in the cards below.

Downloads (the .zip and six CSV tables) need a free account — create one or log in. Everything in them is on this page.

Why the account? It is not a paywall and not a mailing list. Automated scrapers were requesting tens of thousands of these files a day, and each one rebuilds this whole record, which slowed the site for the people reading it. An account is the simplest way to keep downloads open to people and closed to bots.

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.

Current administration

● In priority — no active call senior to this structure's rights affects its district (11 active call(s) checked).

11 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?

The outlook for the weeks ahead is not computable for this structure: this structure is not on the modelled flow network, so no reference gage can honestly stand in for it. 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.

Decreed rights (7)

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.

Water-court filings naming this structure

2 applications 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.

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 291,672 AF. Its most recent year on record, 2025, came in at 166,385 AF — 57% of that, and 3rd 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.
