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 1867-07-01 — 231st 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: 2303331 (1867-07-01). Immediately behind: 2303978 (1867-07-01).

Decreed rights (4)

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. UnitsUsesWhat the court said this water may be used for -- irrigation, municipal supply, augmentation and so on.Case

Recorded use (last 15 years on record)

In a median year this structure has a recorded diversion of 11,060 AF. Its most recent year on record, 2025, came in at 5,905 AF — 53% of that, and 3rd lowest of the 15 years with a recorded volume.

This structure records both diversions and reservoir releases — they are separate water movements and are accounted separately below.
