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 1883-02-15 — 6th most senior of the 1758 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: MITCHELL-COOPER D PL AP1 (1882-10-10). Immediately behind: THOMPKINS DITCH (1883-03-10).
Decreed rights (38)
| 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 226 AF. Its most recent year on record, 1968, came in at 54 AF — 24% of that, and 1st lowest of the 8 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) |
|---|---|---|---|---|
| 1961 | 218 | 4th lowest of 8 · 97% of median | 275 | 0.4 |
| 1962 | 305 | 7th lowest of 8 · 135% of median | 359 | 0.5 |

Trends for this structure
Recorded use shows no clear trend over its last 8 recorded years — which is itself worth knowing.
