Which of its rights are out of priority?
Not computable for this structure: no decreed right on file, so there is no priority to test.
Recorded use (last 15 years on record)
In a median year this structure has a recorded diversion of 412 AF. Its most recent year on record, 2025, came in at 336 AF — 82% of that, and 4th lowest of the 15 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) |
|---|---|---|---|---|---|
| 2011 | 400 | 7th lowest of 15 · 97% of median | 400 | 73 | 8.8 |
| 2012 | 441 | 11th lowest of 15 · 107% of median | 441 | 72 | 6.0 |

Trends for this structure
Recorded use shows no clear trend over its last 15 recorded years — which is itself worth knowing.
How good is our record of it?
Grade C (5/10 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 | absent | no water rights cached for this WDID |
| diversion record | present | 4024 measured days; currency unknown (no data-coverage date to compare against) |
| record continuity | sparse | 39% of the irrigation seasons in 1977-2025 carry measured days |
| published-record stability | stable | no upstream revisions recorded against this structure |
