Where this page's figures come from
Generated 2026-08-28 09:19 by Hydrohistorian. Sources: DWR HydroBase snapshot HydroBase_CO_20260707 (history) + CDSS REST (current), USGS NWIS cross-checks. Engine v0.5.0 (0576005) — every figure regenerates from this named code version and data image.
In short
In a median year over its last 5 recorded years it diverts 6 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.
Current administration
● Fully called out — call at LAST CHANCE DITCH 2 (SOUTH PLATTE RIVER, priority 1863-12-30).
Which of its rights are out of priority?
Not computable for this structure: this structure is not on the modelled flow network, so no reference gage can honestly stand in for it.
Where it sits in line
Priority 1973-11-30 — 7227th most senior of the 21881 structures with decreed rights in this water districtDWR's administrative subdivision of a river basin; the unit calls are usually stated in..
Under prior appropriationColorado's rule for sharing water: first in time, first in right. Age decides, not proximity or need., everything ahead of it in this line is satisfied in full before it receives any water. Immediately ahead: 8003545 (1973-11-17). Immediately behind: 0808995 (1973-12-11).
Decreed rights (1)
| 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. | Units | UsesWhat the court said this water may be used for -- irrigation, municipal supply, augmentation and so on. | Case |

How often is it out of priority?
Across the 8 seasons whose call record is complete enough to judge this structure (2017, 2018, 2020, 2021, 2022, 2023, 2024, 2026), week by week from April. Read these as counts, not rates — 8 seasons is a short record.

Why only 8 seasons, and what the bars mean
Each bar is one week: how many of those seasons that right was out of priority under a call this site can lawfully attribute to this structure. Green is never, red is every season on record.
The short record is a property of DWR's data, not of the river. A call only counts against a structure when we can establish it applies — by the districts named in its set comments, or by stream mile on the same source. DWR did not begin stating affected districts routinely until about 2015: fewer than one call in ten can be judged before then, against roughly two in three since. A season we cannot judge is not a season without calls, so it is dropped rather than counted as quiet — 15 seasons dropped here.
This is a frequency over past seasons, not a forecast. It says nothing about what the division engineer will do this year.
Recorded use (last 9 years on record)
In a median year this structure has a recorded diversion of 6 AF. Its most recent year on record, 1988, came in at 0 AF — 0% of that, and 1st lowest of the 5 years with a recorded volume.
This structure records both diversions and reservoir releases — they are separate water movements and are accounted separately below.

How good is our record of it?
Grade C (6/10 points) — the components below are the finding; the letter alone is not.
The rubric, component by component
| Check | State | Detail |
|---|---|---|
| identity | partial | missing name, structure type, water source |
| decreed rights | on file | 1 right(s), seniority decoded |
| diversion record | fragment | 44 measured day(s) on file (under 180 -- a season, not a history) |
| record continuity | unknown | record too short to assess continuity (needs 2+ years of span and 180+ measured days) |
| published-record stability | stable | no upstream revisions recorded against this structure |
