Which of its rights are out of priority?
Not computable for this structure: no call in the record verifiably applies to this district (statements and caller locations checked).
Where it sits in line
Priority 1859-10-01 — 16th most senior of the 1867 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: NEW DRY CR CARRIER DITCH (1859-10-01). Immediately behind: 0602415 (1859-10-01).
On MAINSTEM at river mile 16.5, it is 29th of 78 down the reach. Immediately upstream: DAVIS RES 1&2. Immediately downstream: LEGGETT DITCH.
Position on the modelled network, not a claim about whose water this is — a stream carries water from many rights at once, and diverted water returns to it.
Decreed rights (12)
| 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 2 years on record)
In a median year this structure has a recorded diversion of 431 AF. Its most recent year on record, 2024, came in at 737 AF — 171% of that, and 2nd lowest of the 2 years with a recorded volume.
| 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 | Days recorded | Peak (cfs) |
|---|---|---|---|---|
| 2023 | 125 | 1st lowest of 2 · 29% of median | 28 | 2.8 |
| 2024 | 737 | 2nd lowest of 2 · 171% of median | 125 | 9.1 |
