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 1877-05-01 — 1st most senior of the 1104 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 behind: RESERVATION DITCH (1880-07-01).

Decreed rights (10)

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
