Current administration

● Junior rights called out — call at SWADLEY LONGAN DITCH (RALSTON CREEK, priority 1861-04-09).

● Junior rights called out — call at CLEAR CR PLATTE RIVER D (CLEAR CREEK, priority 1861-11-01).

● Junior rights called out — call at FARMERS INDEPENDENT DITCH (SOUTH PLATTE RIVER, priority 1865-11-20).

Which of its rights are out of priority?

Under today's controlling call (SWADLEY LONGAN DITCH, priority 1861-04-09): 71 of this structure's 78 rights are out of priority now (call list is 12 days old). (10 call(s) state no district and sit outside this one — not judged, not assumed.) In the 5 past years most like this one (2018, 2024, 2025, 2022, 2017), 5 of the rights shown below were out at least one week in at least one analog year.

How this table is built, and what it is not

“Now” compares each right's admin number with today's most senior applicable active call. The outlook uses flows at ROCKY MOUNTAIN DITCH around 2026-08-09 (the newest reading on file) — currently 40% of that gage's own median for this window — to pick the 5 most similar past years with complete administration records (2005–2026). Only calls that verifiably apply count: DWR's own district statements in the call's set comments, a caller located in this district, or — on the same stream, where DWR records both stream miles (measured from the mouth) — a caller DOWNSTREAM of this structure. An upstream senior cannot demand water this diversion never deprives it of. Calls that state nothing and sit elsewhere are counted as unjudged rather than assumed, which also means the verified record is shorter than the raw one: early calls rarely state districts. For each week it finds the most senior call then in force; a right is out in that week exactly when that call is senior to it, which is why one line prices every right and juniors can be out while seniors keep diverting. “Majority out by” is the first week out in more than half the analog years. A frequency among named historical years, not a probability from a model, and not a forecast of what the division engineer will do. It says how often years whose flow resembled this one were under a call senior to this right in a given week. Snowpack, storage, and the actual administrative decisions of a given season are not modelled. Check the analog years listed: if they do not resemble this year to you, the outlook does not either.

Where it sits in line

Priority 1860-02-25 — 5th most senior of the 1815 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: CLEAR CR PLATTE RIVER D (1860-02-25). Immediately behind: FARMERS HIGHLINE CANAL (1860-02-25).

On MAINSTEM at river mile 49.8, it is 50th of 107 down the reach. Immediately upstream: ROCKY MOUNTAIN DITCH. Immediately downstream: AGRICULTURAL D RT TO CL CR.

Position on the modelled network, not a claim about whose water this is — a stream carries water from many rights at once, and diverted water returns to it.

Decreed rights (82)

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 10,305 AF. Its most recent year on record, 2025, came in at 9,093 AF — 88% of that, and 6th lowest of the 15 years with a recorded volume.
