Current administration

● In priority — no active call senior to this structure's rights affects its district (23 active call(s) checked).

Which of its rights get called out?

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 1910-04-15 — 1079th 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: 0206855 (1910-03-20). Immediately behind: 0807618 (1910-05-22).

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.

Recorded use (last 15 years on record)

In a median year this structure has a recorded diversion of 3,238 AF. Its most recent year on record, 2024, came in at 2,841 AF — 88% of that, and 6th lowest of the 14 years with a recorded volume.

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