FISHER DITCH

Structure dossier · WDID 1500551 · DITCH · SAINT CHARLES RIVER · DWR record

Fisher Ditch is a ditch on Saint Charles River 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 2026-10-15 16:28 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.

In short

In a median year over its last 15 recorded years it diverts 165 acre-feet. It was a party to 1 court cases that also touched 1 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?

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

Filings that would move water above this headgate

1 water-court application in the monthly resumes names a structure on SAINT CHARLES RIVER upstream of this headgate. A new right, exchange or change of use up there changes what arrives down here — the resume is the public notice, and the opposition window is how anyone affected answers it.

Judged on this structure’s own named stream only — a filing on a tributary that joins upstream is not judged here. Filings that name structures only in prose, without a WDID, are invisible to this card. Reading aid, not legal advice; the deadline is computed from C.R.S. 37-92-302(3), and the court’s own notice controls.

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 165 AF. Its most recent year on record, 1973, came in at 30 AF — 18% of that, and 3rd lowest of the 15 years with a recorded volume.
