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 1868-08-01 — 270th 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: 2302435 (1868-06-01). Immediately behind: 2302913 (1868-08-01).
Decreed rights (2)
| 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 1,614 AF. Its most recent year on record, 1964, came in at 1,437 AF — 89% of that, and 6th 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 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 | 2 right(s), seniority decoded |
| diversion record | present | 964 measured days; currency unknown (no data-coverage date to compare against) |
| record continuity | sparse | 17% of the irrigation seasons in 1950-1976 carry measured days |
| published-record stability | stable | no upstream revisions recorded against this structure |
