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 1863-04-01 — 21st most senior of the 1296 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: BIG THOMPSON RIVER (1863-04-01). Immediately behind: SOUTH SIDE DITCH LEFT IN (1863-04-01).
Decreed rights (7)
| 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 5 years on record)
In a median year this structure has a recorded diversion of 4 AF. Its most recent year on record, 2017, came in at 1 AF — 25% of that, and 1st lowest of the 5 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) |
|---|---|---|---|---|---|
| 2013 | 7 | 5th lowest of 5 · 175% of median | 7 | 10 | 1.7 |
| 2014 | 4 | 3rd lowest of 5 · 100% of median | 4 | 3 | 1.1 |
| 2015 | 4 | 3rd lowest of 5 · 100% of median | 4 | 3 | 1.0 |
| 2016 | 2 | 2nd lowest of 5 · 50% of median | 2 | 3 | 0.5 |

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 | 7 right(s), seniority decoded |
| diversion record | fragment | 21 measured day(s) on file (under 180 -- a season, not a history) |
| 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 |
