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 1861-03-08 — 15th most senior of the 1289 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: LONGMONT SOUTH PIPELINE (1861-03-08). Immediately behind: HIGHLAND DITCH (1861-03-08).
Decreed rights (47)
| 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 15 years on record)
In a median year this structure has a recorded diversion of 7,475 AF. Its most recent year on record, 2024, came in at 9,787 AF — 131% of that, and 13th lowest of the 15 years with a recorded volume.

Trends for this structure
Recorded use shows no clear trend over its last 15 recorded years — which is itself worth knowing.
