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 1876-05-01 — 518th 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: 2305521 (1876-04-30). Immediately behind: 2304006 (1876-05-01).
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 |

Recorded use (last 15 years on record)
In a median year this structure has a recorded diversion of 869 AF. Its most recent year on record, 1983, came in at 851 AF — 98% of that, and 6th lowest of the 13 years with a recorded volume.
This structure records both diversions and reservoir releases — they are separate water movements and are accounted separately below.
| 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 | Released (AF) | Days recorded | Peak (cfs) |

Trends for this structure
Recorded use shows no clear trend over its last 13 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 | 1 right(s), seniority decoded |
| diversion record | present | 1526 measured days; currency unknown (no data-coverage date to compare against) |
| record continuity | sparse | 18% of the irrigation seasons in 1950-1989 carry measured days |
| published-record stability | stable | no upstream revisions recorded against this structure |
