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 1888-10-20 — 10th most senior of the 112 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: WILSON SUMP PUMP (1888-10-20). Immediately behind: WILSON SUMP IMPOUNDMENT (1888-10-20).
Decreed rights (1)
| 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 10 years on record)
In a median year this structure has a recorded diversion of 2,109 AF. Its most recent year on record, 2025, came in at 805 AF — 38% of that, and 3rd lowest of the 10 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) |
|---|---|---|---|---|---|
| 2016 | 437 | 1st lowest of 10 · 21% of median | 437 | 77 | 5.7 |
| 2017 | 2,116 | 6th lowest of 10 · 100% of median | 2,116 | 193 | 7.7 |
| 2018 | 2,118 | 9th lowest of 10 · 100% of median | 2,118 | 193 | 7.7 |
| 2019 | 2,116 | 6th lowest of 10 · 100% of median | 2,116 | 193 | 9.4 |
| 2020 | 2,120 | 10th lowest of 10 · 100% of median | 2,120 | 193 | 9.7 |

Call-derived yield: senior right divertible 32.7% of a median season / 3.3% dry-year.
Trends for this structure
Recorded use shows no clear trend over its last 10 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.
