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 1987-06-30 — 1611th most senior of the 2864 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: GAEDE WELL NO 4 (1987-02-18). Immediately behind: WOODMOOR QAL-4 (1987-06-30).
Decreed rights (5)
| 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 8 years on record)
In a median year this structure has a recorded diversion of 306 AF. Its most recent year on record, 2025, came in at 315 AF — 103% of that, and 6th lowest of the 8 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) |
|---|---|---|---|---|---|
| 2018 | 59 | 1st lowest of 8 · 19% of median | 59 | 61 | 1.1 |
| 2019 | 310 | 5th lowest of 8 · 102% of median | 310 | 331 | 1.3 |
| 2020 | 301 | 4th lowest of 8 · 98% of median | 301 | 336 | 1.1 |
| 2021 | 166 | 2nd lowest of 8 · 54% of median | 166 | 274 | 1.4 |
| 2022 | 457 | 8th lowest of 8 · 150% of median | 457 | 365 | 2.1 |
| 2023 | 385 | 7th lowest of 8 · 126% of median | 385 | 365 | 1.9 |

Trends for this structure
Recorded use shows no clear trend over its last 8 recorded years — which is itself worth knowing.
How good is our record of it?
Grade A (9/10 points) — the components below are the finding; the letter alone is not.
