Transit Mix West Pit is a reservoir on Arkansas 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 2026-10-14 02:17 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
In short
In a median year over its last 7 recorded years it diverts 145 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.
Well permit on file (1)
DWR ties this well permit to WDID 1406220. A permit is the authorization to construct and use the well — not a water right, and separate from the decrees on this page (three things called “well”).
| Permit | Use | Status | Depth | Static level | Yield | Completed |
|---|---|---|---|---|---|---|
| 44558-F | Other | Well Constructed | 30 ft | — | — | 1995-02-09 |

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 ARKANSAS 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 7 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 145 AF. Its most recent year on record, 2021, came in at 125 AF — 86% of that, and 2nd lowest of the 7 years with a recorded volume.
| Year | Diverted (AFA volume: one acre covered a foot deep, about 326,000 gallons -- roughly a suburban household's outdoor use for a year.) | Compared with its own record | Days recorded | Peak (cfs) |
|---|---|---|---|---|
| 2015 | 20 | 1st lowest of 7 · 14% of median | 61 | 0.2 |
| 2016 | 145 | 4th lowest of 7 · 100% of median | 366 | 0.3 |
| 2017 | 128 | 3rd lowest of 7 · 88% of median | 335 | 0.3 |
| 2018 | 145 | 4th lowest of 7 · 100% of median | 365 | 0.3 |
| 2019 | 147 | 7th lowest of 7 · 101% of median | 365 | 0.3 |
| 2020 | 145 | 4th lowest of 7 · 100% of median | 366 | 0.3 |

How good is our record of it?
Grade B (7/10 points) — the components below are the finding; the letter alone is not.
The rubric, component by component
| Check | State | Detail |
|---|---|---|
| identity | complete | name, type, and water source all on file |
| decreed rights | absent | no water rights cached for this WDID |
| diversion record | present | 2162 measured days; currency unknown (no data-coverage date to compare against) |
| record continuity | continuous | 100% of the irrigation seasons in 2015-2021 carry measured days |
| published-record stability | stable | no upstream revisions recorded against this structure |
