MID FORK SO PLATTE ☆ My Water

In short

MID FORK SO PLATTE holds 1 decreed right on MIDDLE FORK SOUTH PLATTE. No active call senior to its rights reaches its district today (17 active calls checked), so it is in priority now. 5 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: this structure is not on the modelled flow network, so no reference gage can honestly stand in for it. It was a party to 63 court cases that also touched 123 other structures.

Assembled from the figures on this page — every number above is checked against them before it is shown (5 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 (17 active call(s) checked).

5 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: 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 1867-07-01 — 226th most senior of the 21886 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: MICHIGAN CREEK (1867-07-01)☆. Immediately behind: SACRAMENTO CREEK (1867-07-01)☆.

Decreed rights (1)

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 6.765 cfs decreed rate, the average day over the last 6 year(s) had 6.731 cfs in priority (99% of the decree). No call in effect is a free river — that was 6.4% of days.

On 8 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. A call began or ended mid-day on 33 of these days.

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 →

How often is it out of priority?

Across the 11 seasons whose call record is complete enough to judge this structure (2016, 2017, 2018, 2019, 2020, 2021, 2022, 2023, 2024, 2025, 2026), week by week from April.

Structures it shares court cases with

This structure was a party to 63 court cases that also touched 123 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.

51 further shared cases not shown — the most specific are listed first, since a case binding two structures says more than one binding a dozen.

Also a party to 1 omnibus adjudication (W6355, 33 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.
