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 1874-10-14 — 464th 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: 2300963 (1874-10-14). Immediately behind: 2300985 (1874-10-31).
Decreed rights (12)
| 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 |

Recorded use (last 15 years on record)
In a median year this structure has a recorded diversion of 2,620 AF. Its most recent year on record, 2024, came in at 3,466 AF — 132% of that, and 11th lowest of the 14 years with a recorded volume.
This structure records both diversions and reservoir releases — they are separate water movements and are accounted separately below.

Trends for this structure
Recorded use shows no clear trend over its last 14 recorded years — which is itself worth knowing.
How good is our record of it?
Grade B (8/10 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 | on file | 12 right(s), seniority decoded |
| diversion record | present | 4509 measured days; currency unknown (no data-coverage date to compare against) |
| record continuity | patchy | 52% of the irrigation seasons in 1984-2024 carry measured days |
| published-record stability | stable | no upstream revisions recorded against this structure |
