DRY CREEK DAVIDSON DITCH ☆ My Water

Who owns it

• Dry Creek-Davidson Ditch Company (nonprofit corporation) — probable match, from the Colorado Secretary of State business record ↗; verify before relying on it. A nonprofit corporation of this name, in good standing, with its principal office in Longmont; matched on the name and the location, not confirmed by the company.

DWR’s own records name no owner for a ditch, reservoir or well, so this comes from the source shown and can be out of date. Organisations only: a private landowner’s name is never listed.

The record and the river

Where this structure is measured

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 2026-10-12 14:00 (2.8 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 DCDDITCO ↗ (DRY CREEK DAVIDSON 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

DRY CREEK DAVIDSON DITCH holds 1 decreed right on SOUTH 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: 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 1,406 acre-feet. That use is falling by about 75.1 acre-feet a year over 15 years (p=0.022821503671488053). It was a party to 3 court cases that also touched 4 other structures.

Assembled from the figures on this page — every number above is checked against them before it is shown (11 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: 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 1863-05-01 — 74th 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: COTTONWOOD DITCH 2 (1863-04-15)☆. Immediately behind: 0602417 (1863-05-01)☆.

On SOUTH BOULDER CREEK at river mile 17.3, it is 40th of 59 down the reach. Immediately upstream: HUNTER/HINE POND☆. Immediately downstream: BURKES RES 1☆.

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 (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 16.748 cfs decreed rate, the average day over the last 6 year(s) had 13.165 cfs in priority (79% of the decree). No call in effect is a free river — that was 13.0% of days.

On 24 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 28 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 →

Filings that would move water above this headgate

4 water-court applications in the monthly resumes name a structure on SOUTH 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 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 3 court cases that also touched 4 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 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 1,406 AF. Its most recent year on record, 2025, came in at 134 AF — 10% of that, and 1st lowest of the 15 years with a recorded volume.

Trends for this structure

Recorded use is falling over its last 15 recorded years (-75 AF/yr, Mann-Kendall p=0.023).

Its reference gage, Dry Creek Davidson Ditch: no clear flow trend.
