Dieckman Ditch No 11 is a ditch on Macey Creek 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 2026-10-22 08:18 by Hydrohistorian. Sources: DWR HydroBase snapshot HydroBase_CO_20260928 (history) + CDSS REST (current), USGS NWIS cross-checks. Engine v0.5.0 (71f534c) — every figure regenerates from this named code version and data image.
In short
In a median year over its last 8 recorded years it diverts 18 acre-feet. That use is falling by about 0.8 acre-feet a year over 8 years (p=0.035447892552460836).
Assembled from the figures on this page — every number above is checked against them before it is shown (5 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.
Structures it shares court cases with
Also a party to 1 omnibus
adjudication
(21CW3078, 72 structures).
Those settled many rights at once and are listed separately: they say
these structures were adjudicated together, not that they deal with
each other.
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 8 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 18 AF. Its most recent year on record, 2004, came in at 2 AF — 11% of that, and 2nd lowest of the 8 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) |
|---|---|---|---|---|
| 1969 | 34 | 8th lowest of 8 · 194% of median | 49 | 0.4 |
| 1970 | 31 | 7th lowest of 8 · 177% of median | 155 | 0.4 |
| 1975 | 26 | 6th lowest of 8 · 149% of median | 14 | 1.0 |
| 1976 | 8 | 3rd lowest of 8 · 46% of median | 13 | 0.4 |
| 1988 | 0 | 1st lowest of 8 · 0% of median | 1 | 0.0 |
| 1999 | 21 | 5th lowest of 8 · 120% of median | 31 | 0.4 |
| 2001 | 14 | 4th lowest of 8 · 80% of median | 20 | 0.4 |
| 2004 | 2 | 2nd lowest of 8 · 11% of median | 5 | 0.2 |
Trends for this structure
Recorded use is falling over its last 8 recorded years (-1 AF/yr, Mann-Kendall p=0.035).
How good is our record of it?
Grade C (5/10 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 | 288 measured days; currency unknown (no data-coverage date to compare against) |
| record continuity | sparse | 4% of the irrigation seasons in 1969-2004 carry measured days |
| published-record stability | stable | no upstream revisions recorded against this structure |
