Current administration

● Fully called out — call at LAST CHANCE DITCH 2 (SOUTH PLATTE RIVER, priority 1863-12-30).

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 1873-06-25 — 413th 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: 0801171 (1873-06-20). Immediately behind: 0801279 (1873-06-30).

Decreed rights (22)

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 3,032 AF. Its most recent year on record, 2025, came in at 3,087 AF — 102% of that, and 10th 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.

How good is our record of it?

Grade B (7/10 points) — the components below are the finding; the letter alone is not.

identity complete name, type, and water source all on file
decreed rights on file 22 right(s), seniority decoded
diversion record present 3012 measured days; currency unknown (no data-coverage date to compare against)
record continuity sparse 34% of the irrigation seasons in 1984-2025 carry measured days
