SOUTH CHEYENNE PIPELINE ☆ My Water

The record and the river

In short

SOUTH CHEYENNE PIPELINE holds 9 decreed rights on SOUTH CHEYENNE CREEK. No active call senior to its rights reaches its district today (20 active calls checked), so it is in priority now. 14 further calls state no district and sit outside this one, so they are counted here rather than assumed either way. That is today's position; the weeks ahead cannot be projected for it: no call in the record verifiably applies to this district (statements and caller locations checked). In a median year over its last 15 recorded years it diverts 972 acre-feet. It was a party to 3 court cases that also touched 4 other structures.

Assembled from the figures on this page — every number above is checked against them before it is shown (7 checked). The detail, with its method, is in the cards below.

Current administration

● In priority — no active call senior to this structure's rights affects its district (20 active call(s) checked).

14 further calls state no district and sit outside this one, so they are counted here rather than assumed either way.

Which of its rights are out of priority?

The outlook for the weeks ahead is not computable for this structure: no call in the record verifiably applies to this district (statements and caller locations checked). 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 1860-09-01 — 2nd most senior of the 2872 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: RUXTON CREEK PIPELINE (1860-02-20)☆. Immediately behind: MESA PIPELINE (1860-09-01)☆.

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 (9)

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.

How much of this decree was in priority, by day

A right is in priority on a day when it is senior to every call administering this structure. Of its 23.85 cfs decreed rate, the average day over the last 6 year(s) had 22.574 cfs in priority (95% of the decree). No call in effect is a free river — that was 0.0% of days.

On 1209 days some rights were in priority and others were not — seniority splits a decree rather than switching it off. Calls are set and released at a time of day, not at midnight, so a day is counted by the hour: a call setting at 4pm costs that day a third of its rate, not all of it.

This is paper water. It is the decreed rate that was in priority — not water that was physically in the stream, and not water this structure diverted. A ditch can be in priority for 50 cfs on a day the creek carries five. What that distinction means →

Structures it shares court cases with

This structure was a party to 3 court cases that also touched 4 other structures — changes of water right, augmentation plans, exchanges. Being parties to the same case does not by itself mean water moved between them; which way it ran, and how much, is in the decree.

Also a party to 2 omnibus adjudications (CA13801, 149 structures; CA10146, 126 structures). Those settled many rights at once and are listed separately: they say these structures were adjudicated together, not that they deal with each other.

Recorded use (last 15 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 972 AF. Its most recent year on record, 2025, came in at 903 AF — 93% of that, and 7th lowest of the 15 years with a recorded volume.

Call-derived yield: senior right divertible 96.3% of a median season / 56.5% dry-year.

Trends for this structure

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

Its reference gage, Fountain Creek at 8th Street: no clear flow trend.
