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 14 years on record)
In a median year this structure has a recorded diversion of 380 AF. Its most recent year on record, 2024, came in at 469 AF — 123% 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.
| 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) |
|---|---|---|---|---|---|
| 2010 | 79 | 2nd lowest of 14 · 21% of median | 79 | 61 | 1.5 |
| 2011 | 459 | 10th lowest of 14 · 121% of median | 459 | 335 | 1.4 |
| 2012 | 322 | 6th lowest of 14 · 85% of median | 322 | 244 | 0.8 |

| 2014 | 198 | 4th lowest of 14 · 52% of median | 198 | 236 | 0.9 |

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 (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 | absent | no water rights cached for this WDID |
| diversion record | present | 3290 measured days; currency unknown (no data-coverage date to compare against) |
| record continuity | continuous | 100% of the irrigation seasons in 2010-2024 carry measured days |
| published-record stability | stable | no upstream revisions recorded against this structure |
