STROMQUIST POND 1, SOUTH 0603392B — — named for this WDID

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.

Flowing now

0.0 cfs as of 2026-10-13 00:00 (2.5 h ago)

Zero is a real reading: the gage is reporting, and it says this structure is not diverting right now.

Provisional 15-minute telemetry from 0603392A ↗ (STROMQUIST PONDS INLET). Raw, not the approved record — it is never merged into the diversion history below. DWR publishes the official diversion record after the water year closes and is approved, which is why that record ends months back while this reads minutes ago.

In short

STROMQUIST POND 1 holds 2 decreed rights on BOULDER CREEK. A call at RURAL DITCH on BOULDER CREEK (1862-05-09) 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: no gage record for this year at this date, so there is nothing to find analogs for. In a median year over its last 10 recorded years it diverts 334 acre-feet. It was a party to 5 court cases that also touched 6 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).

Which of its rights are out of priority?

The outlook for the weeks ahead is not computable for this structure: no gage record for this year at this date, so there is nothing to find analogs for. 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

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: 0600825 (1971-12-31). Immediately behind: STROMQUIST POND 2 (1982-07-01).

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 (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

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.

Filings that would move water above this headgate

4 water-court applications in the monthly resumes name a structure on BOULDER CREEK 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.

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.

Snow sets the clock here. In the driest third of snow years (4 seasons), the call settled in for the season around July 15 (June 3 to July 15 across those years); in 1 of them it never lifted at all. In the middle third (4 seasons), the call settled in for the season around June 24 (June 17 to July 8 across those years); in 1 of them it never lifted at all. In the wettest third (4 seasons), the call settled in for the season around June 24 (June 17 to June 24 across those years); in 2 of them it never lifted at all.

Snow years ranked by the district’s April 1 snow-water percentile across 3 SNOTEL sites; 12 seasons carry both a snow reading and a judgeable call record. How the past played out, not a forecast.

Why only 12 seasons, and what the bars mean

Each bar is one week: how many of those seasons that right was out of priority under a call this site can lawfully attribute to this structure. Green is never, red is every season on record.

The short record is a property of DWR's data, not of the river. A call only counts against a structure when we can establish it applies — by the districts named in its set comments, or by stream mile on the same source. DWR did not begin stating affected districts routinely until about 2015: fewer than one call in ten can be judged before then, against roughly two in three since. A season we cannot judge is not a season without calls, so it is dropped rather than counted as quiet — 11 seasons dropped here.

This is a frequency over past seasons, not a forecast. It says nothing about what the division engineer will do this year.

Recorded use (last 10 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 334 AF. Its most recent year on record, 2024, came in at 168 AF — 50% of that, and 2nd lowest of the 10 years with a recorded volume.

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