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 97 AF. Its most recent year on record, 2025, came in at 58 AF — 60% of that, and 4th lowest of the 15 years with a recorded volume.

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 | 3531 measured days; currency unknown (no data-coverage date to compare against) |
| record continuity | sparse | 22% of the irrigation seasons in 1950-2025 carry measured days |
| published-record stability | stable | no upstream revisions recorded against this structure |
Advisory reading aid on public data — not an administrative or legal conclusion, not a title opinion, and not a substitute for DWR administration or an engineer's analysis. Methodology review status is disclosed at hydrohistorian's basin pages.
