Where this page's figures come from

Generated 2026-09-18 12:41 by Hydrohistorian. Sources: DWR HydroBase snapshot HydroBase_CO_20260707 (history) + CDSS REST (current), USGS NWIS cross-checks. Engine v0.5.0 (956f090) — every figure regenerates from this named code version and data image.

In short

In a median year over its last 15 recorded years it diverts 243 acre-feet. It was a party to 1 court cases that also touched 5 other structures.

Assembled from the figures on this page — every number above is checked against them before it is shown (4 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?

Not computable for this structure: no decreed right on file, so there is no priority to test.

Structures it shares court cases with

This structure was a party to 1 court case that also touched 5 other structures — changes of water right, augmentation plans, exchanges. Being parties to the same case does not by itself mean water moved between them; which way it ran, and how much, is in the decree.

How this is derived

Every court action DWR records for a structure carries its case number. Where one case number appears in the records of several structures, those structures were parties to the same proceeding. This is read straight from the cached transaction tables — no document was interpreted to build it. Case numbers are validated against the known Colorado formats first: the case column also contains stray dates (10/04/1884 appears on 98 Clear Creek rows), and treating one as a case number would invent a shared proceeding between 60 unrelated structures. Cases spanning more than 12 structures are separated out as omnibus adjudications. The filing year comes from the case number, not from the row's adjudication date — that date belongs to the water right the action describes, so a 2006 case legitimately carries a 1989 date.

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 243 AF. Its most recent year on record, 1991, came in at 180 AF — 74% of that, and 4th lowest of the 15 years with a recorded volume.

Trends for this structure

Recorded use shows no clear trend over its last 15 recorded years — which is itself worth knowing.

How good is our record of it?

Grade C (6/10 points) — the components below are the finding; the letter alone is not.
