GOOSE HAVEN RESERVOIR COMPLEX ☆ My Water

The record and the river

In short

GOOSE HAVEN RESERVOIR COMPLEX holds 11 decreed rights on BOULDER CREEK. A call at RURAL DITCH on BOULDER CREEK (1862-05-09), and 1 other currently reaches it: fully called out. 7 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. In a median year over its last 15 recorded years it diverts 3,008 acre-feet. It was a party to 4 court cases that also touched 5 other structures.

Assembled from the figures on this page — every number above is checked against them before it is shown (8 checked). The detail, with its method, is in the cards below.

Current administration

● Fully called out — call at RURAL DITCH (BOULDER CREEK, priority 1862-05-09).

● Fully called out — call at HOWELL DITCH (BOULDER CREEK, priority 1860-04-01).

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 1872-04-15 — 89th most senior of the 1867 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: CHURCH DITCH(UPPER) (1870-09-20)☆. Immediately behind: BASELINE RES (1872-04-15)☆.

Decreed rights (11)

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 1.73 cfs decreed rate, the average day over the last 6 year(s) had 0.206 cfs in priority (12% of the decree). No call in effect is a free river — that was 9.5% of days.

On 26 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 26 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 →

Water-court filings naming this structure

4 applications in the monthly water-court resumes explicitly reference this WDID. The resume is the earliest public notice of a new claim (C.R.S. 37-92-302) — years before anything reaches the decree record below. Most applications name structures by name rather than WDID, so absence here is weak evidence of absence.

Source: Judicial Branch combined monthly resumes (archive), indexed nightly; WDIDs attached only when a 7-digit token in the filing matches DWR’s structure inventory.

How often is it out of priority?

Across the 12 seasons whose call record is complete enough to judge this structure (2015, 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 4 court cases that also touched 5 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 1 omnibus adjudication (85CW0119, 19 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 3,008 AF. Its most recent year on record, 2024, came in at 70 AF — 2% of that, and 2nd lowest of the 15 years with a recorded volume.

This structure records both diversions and reservoir releases — they are separate water movements and are accounted separately below.

Trends for this structure

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