Current administration
● In priority — no active call senior to this structure's rights affects its district (23 active call(s) checked).
Where it sits in line
Priority 1889-02-28 — 760th most senior of the 21881 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: 2300749 (1888-12-31). Immediately behind: 2305540 (1889-05-31).
Decreed rights (2)
| 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 7 years on record)
In a median year this structure has a recorded diversion of 26 AF. Its most recent year on record, 2025, came in at 0 AF — 0% of that, and 1st lowest of the 6 years with a recorded volume.
This structure records both diversions and reservoir releases — they are separate water movements and are accounted separately below.
