ECCV AUG SOUTH PLATTE EMPIRE TO BIJOU IM

Structure dossier · WDID 0102858 · REACH · SOUTH PLATTE RIVER · DWR record

Eccv Aug South Platte Empire To Bijou Im is a water structure on South Platte River in Colorado. This page is its public record: the water it has a right to, whether it may take it today, and its history, compiled from the Colorado Division of Water Resources.

Where this page's figures come from

Where this structure is measured

GageFlowing nowRecordHow we know
SOUTH PLATT RIVER AT BIJOU CANAL HEADGATE PLABIJCO — — co-located, 101 m

A green link is DWR's own: either its telemetry inventory maps this WDID to that station, or the station is named for this WDID (0700553 → 0700553A). An amber one is ours — the station sits within 250 m and shares a distinctive word with this structure's name, which is a strong hint rather than a DWR statement that this gage meters this structure. Wrong? Tell us.

In short

ECCV AUG SOUTH PLATTE EMPIRE TO BIJOU IM holds 2 decreed rights on SOUTH PLATTE RIVER. A call at STERLING IRR CO DITCH 1 on SOUTH PLATTE RIVER (1936-01-13), and 1 other currently reaches it: fully called out. 1 further call state no district and sit outside this one, so it is counted here rather than assumed either way. That is today's position; the weeks ahead cannot be projected for it: this structure is not on the modelled flow network, so no reference gage can honestly stand in for it. In a median year over its last 14 recorded years it diverts 735 acre-feet. It was a party to 1 court cases that also touched 2 other structures.

Assembled from the figures on this page — every number above is checked against them before it is shown (9 checked). The detail, with its method, is in the cards below.

Current administration

● Fully called out — call at STERLING IRR CO DITCH 1 (SOUTH PLATTE RIVER, priority 1936-01-13).

● Fully called out — call at HARMONY DITCH 1 (SOUTH PLATTE RIVER, priority 1995-12-31).

Which of its rights are out of priority?

The outlook for the weeks ahead is not computable for this structure: this structure is not on the modelled flow network, so no reference gage can honestly stand in for it. Today’s position is a separate question, and it is answered in Current administration above — that screen reads the district’s active calls and needs no reference gage.

Where it sits in line

Priority 2009-12-31 — 6121st most senior of the 7708 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: MEADOW SPRINGS RANCH WELL B (2009-12-30). Immediately behind: YOCAM POND 2 (1963-06-01).

Decreed rights (2)

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. Alt-pointAn absolute amount decreed at another structure that may be diverted here instead -- an alternate point of diversion or an exchange. DWR calls this the APEX amount; a right showing 0.0 absolute but an alt-point amount is exercised here under another structure's decree. Decreed forWhat the court said this water may be used for -- irrigation, municipal supply, augmentation and so on.Case
58439.00000 2009-12-312009-12-31 0.0 cfs 0.0 112.47 cfs Municipal, Augmentation +1 09CW0283
59590.00000 2013-02-242013-12-31 0.0 cfs 0.0 8.08 cfs Municipal, Augmentation +1 09CW0283

Amounts marked cfs are flow rates; AF are stored volumes (storage rights are decreed in acre-feet). An absolute amount of 0.0 beside an alt-point amount is not a dead right: the water is decreed at another structure, and that row records permission to divert it here instead (an alternate point or exchange). A case listing several numbers reflects the original decree plus later change cases.

Recorded use (last 14 years on record)

Years far under the decreed amount? That gap has a name — paper water vs. wet water, explained on this structure.

In a median year this structure has a recorded diversion of 735 AF. Its most recent year on record, 2025, came in at 2,368 AF — 322% of that, and 11th lowest of the 14 years with a recorded volume.
