STONEWALL SPRINGS SOUTH RESERVOIR ☆ My Water

The record and the river

Current administration

● Junior rights called out — call at ARKANSAS RIVER COMPACT(COLORADO-KANSAS STATE LINE) (ARKANSAS RIVER, priority 1949-05-30).

● Junior rights called out — call at JOHN MARTIN RESERVOIR (ARKANSAS RIVER, priority 1905-04-07).

Which of its rights are out of priority?

The outlook for the weeks ahead is not computable for this structure: only 3 analog year(s) have both flow and a complete administration record; 4 needed. 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 1887-05-01 — 24th most senior of the 1361 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: EXCELSIOR DITCH (1887-05-01)☆. Immediately behind: STONEWALL SPRINGS CENTRAL RESERVOIR (1887-05-01)☆.

On MAINSTEM at river mile 46.5, it is 453rd of 927 down the reach. Immediately upstream: 1413812☆. Immediately downstream: STONEWALL SPRINGS NORTH RESERVOIR☆.

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 (3)

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 60.0 cfs decreed rate, the average day over the last 6 year(s) had 23.045 cfs in priority (38% of the decree). No call in effect is a free river — that was 0.0% of days.

On 52 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 →

Filings that would move water above this headgate

1 water-court application in the monthly resumes names a structure on ARKANSAS RIVER upstream of this headgate. A new right, exchange or change of use up there changes what arrives down here — the resume is the public notice, and the opposition window is how anyone affected answers it.

Judged on this structure’s own named stream only — a filing on a tributary that joins upstream is not judged here. Filings that name structures only in prose, without a WDID, are invisible to this card. Reading aid, not legal advice; the deadline is computed from C.R.S. 37-92-302(3), and the court’s own notice controls.

Structures it shares court cases with

This structure was a party to 2 court cases that also touched 3 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.

Recorded use (last 4 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 768 AF. Its most recent year on record, 2025, came in at 1,288 AF — 168% of that, and 3rd 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.

Call-derived yield: senior right divertible 0.0% of a median season / 0.0% dry-year.
