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 1972-05-08 — 349th most senior of the 726 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: KELLEY WELL (1970-12-14). Immediately behind: AUBERT RESERVOIR (1972-09-01).
Decreed rights (3)
| 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 2 years on record)
In a median year this structure has a recorded diversion of 208 AF. Its most recent year on record, 2013, came in at 367 AF — 176% of that, and 2nd lowest of the 2 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) |
|---|---|---|---|---|---|
| 2012 | 49 | 1st lowest of 2 · 24% of median | 49 | 177 | 0.3 |
| 2013 | 367 | 2nd lowest of 2 · 176% of median | 367 | 96 | 3.2 |
How good is our record of it?
Grade B (7/10 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 | 3 right(s), seniority decoded |
| diversion record | present | 273 measured days; currency unknown (no data-coverage date to compare against) |
| 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 |
