The record and the river
Where this structure is measured
| Gage | Flowing now | Record | How we know |
|---|---|---|---|

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 last reported 2026-09-24 02:00
Zero is a real reading: the gage is reporting, and it says this structure is not diverting right now.
This station has not reported in over a day, so treat the number as the last thing it said, not as now.
Provisional 15-minute telemetry from SBBDITCO ↗ (SOUTH BOULDER & BEAR CREEK DITCH). 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
S BOULDER BEAR CR DITCH holds 26 decreed rights on SOUTH BOULDER CREEK. A call at RURAL DITCH on BOULDER CREEK (1862-05-09), and 1 other currently reaches it: junior rights 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 15 recorded years it diverts 392 acre-feet. It was a party to 4 court cases that also touched 20 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.

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
Priority 1859-10-01 — 7th 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: ENTERPRISE DITCH (1859-10-01). Immediately behind: SOUTH BOULDER CANON DITCH (1859-10-01).
On SOUTH BOULDER CREEK at river mile 12.3, it is 17th of 59 down the reach. Immediately upstream: GOODHUE DITCH. Immediately downstream: DRY CREEK NO 2 DITCH.
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 (26)
| 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.
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 29.77 cfs decreed rate, the average day over the last 6 year(s) had 21.477 cfs in priority (72% of the decree). No call in effect is a free river — that was 7.8% of days.
On 370 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 17 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 this is worked out, and what it cannot tell you
- This is a decreed rate that was in priority -- paper water, not water that was available or diverted.
- Augmentation plans, exchanges and substitute supply plans let a structure divert lawfully while out of priority; none are modelled.
- Calls on the river this source flows into are included without a position test, so curtailment can be over-reported where the calling point sits above the confluence.
- DWR's administration is the authority. Scored against DWR's own call analysis, this method agreed on 95.5% of 85,822 structure-days (2026-08-29).
- Calls considered for this structure: 5941, of which 5289 sit on a river it flows into.

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.

Snow sets the clock here. In the driest third of snow years (3 seasons), the call settled in for the season around June 3; in 1 of them it never lifted at all. In the middle third (5 seasons), the call settled in for the season around June 24 (June 17 to July 1 across those years); in 1 of them it never lifted at all. In the wettest third (3 seasons), the call settled in for the season around June 24 (May 6 to June 24 across those years); in 1 of them it never lifted at all.
Snow years ranked by the district’s April 1 snow-water percentile across 3 SNOTEL sites; 11 seasons carry both a snow reading and a judgeable call record. How the past played out, not a forecast.
Why only 11 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 — 12 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.
Structures it shares court cases with
This structure was a party to 4 court cases that also touched 20 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.
| Case | Filed | Also touched |
|---|---|---|
93CW0025 |
1993 | LOWER BOULDER DITCH, ENTERPRISE DITCH, 0600762, LAFAYETTE DITCH 1 and 1 more |

1980 | COMMUNITY DITCH, DAVIDSON DITCH, DRY CREEK NO 2 DITCH, EAST BOULDER DITCH and 6 more |

2005 | LOWER BOULDER DITCH, COMMUNITY DITCH, LEYNER COTTONWOOD DITCH, DRY CREEK NO 2 DITCH and 7 more |
Also a party to 7 omnibus
adjudications
(80CW0468, 28 structures; W8346, 20 structures; 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.
How this is derived
Every court action DWR records for a structure
carries its case number. Where one case number appears in the records of
several structures, those structures were parties to the same proceeding.
This is read straight from the cached transaction tables — no
document was interpreted to build it. Case numbers are validated against
the known Colorado formats first: the case column also contains stray
dates (10/04/1884 appears on 98 Clear Creek rows), and
treating one as a case number would invent a shared proceeding between
60 unrelated structures. Cases spanning more than
12 structures are separated out as omnibus
adjudications. The filing year comes from the case number, not from the
row's adjudication date — that date belongs to the water right the
action describes, so a 2006 case legitimately carries a 1989 date.
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 392 AF. Its most recent year on record, 2025, came in at 371 AF — 95% of that, and 7th lowest of the 15 years with a recorded volume.
| Year | Diverted (AFA volume: one acre covered a foot deep, about 326,000 gallons -- roughly a suburban household's outdoor use for a year.) | Compared with its own record | Days recorded | Peak (cfs) |

Trends for this structure
Recorded use shows no clear trend over its last 15 recorded years — which is itself worth knowing.
Its reference gage, South Boulder & Bear Creek Ditch: no clear flow trend.
How good is our record of it?
Grade A (9/10 points) — the components below are the finding; the letter alone is not.
