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 1874-10-01 — 461st 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: 2302908 (1874-10-01). Immediately behind: 2303981 (1874-10-01).

Decreed rights (31)

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 5 years on record)

In a median year this structure has a recorded diversion of 178 AF. Its most recent year on record, 2005, came in at 1,632 AF — 919% of that, and 4th lowest of the 4 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.

The rubric, component by component
CheckStateDetail
identity complete name, type, and water source all on file
decreed rights on file 31 right(s), seniority decoded
diversion record fragment 45 measured day(s) on file (under 180 -- a season, not a history)
record continuity unknown record too short to assess continuity (needs 2+ years of span and 180+ measured days)
published-record stability stable no upstream revisions recorded against this structure
