Who owns it
- The Handy 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 Berthoud; 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DWR’s own records name no owner for a ditch, reservoir or well, so this comes from the source shown and can be out of date.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.

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

Zero is a real reading: the gage is reporting, and it says this structure is not diverting right now.
Provisional 15-minute telemetry from HANDITCO ↗ (HANDY 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
HANDY DITCH holds 24 decreed rights on BIG THOMPSON RIVER. As of 2026-09-27, 18 of them are out of priority under a call at admin 8522.00000 placed by FARMERS IRRIGATION CANAL. Its 6 most senior rights, back to 1861-11-10, keep diverting. 6 further calls state no district and sit outside this one, so they are counted here rather than assumed either way. In a median year over its last 15 recorded years it diverts 13,503 acre-feet. It was a party to 10 court cases that also touched 29 other structures.

Current administration
● Junior rights called out — call at FARMERS IRRIGATION CANAL (BIG THOMPSON RIVER, priority 1873-04-30).
Which of its rights are out of priority?
Under today's controlling call (FARMERS IRRIGATION CANAL, priority 1873-04-30): 18 of this structure's 24 rights are out of priority now. (6 call(s) state no district and sit outside this one — not judged, not assumed.) In the 5 past years most like this one (2008, 2007, 2017, 2011, 2012), 6 of the rights shown below were out at least one week in at least one analog year.

How this table is built, and what it is not
“Now” compares each right's admin number with today's most senior applicable active call. The outlook uses flows at CHARLES HANSEN FEEDER CANAL WASTEWAY TO BIG THOMPSON around 2026-09-27 (the newest reading on file) — currently 115% of that gage's own median for this window — to pick the 5 most similar past years with complete administration records (2004–2026). Only calls that verifiably apply count: DWR's own district statements in the call's set comments, a caller located in this district, or — on the same stream, where DWR records both stream miles (measured from the mouth) — a caller DOWNSTREAM of this structure. An upstream senior cannot demand water this diversion never deprives it of. Calls that state nothing and sit elsewhere are counted as unjudged rather than assumed, which also means the verified record is shorter than the raw one: early calls rarely state districts. For each week it finds the most senior call then in force; a right is out in that week exactly when that call is senior to it, which is why one line prices every right and juniors can be out while seniors keep diverting. “Majority out by” is the first week out in more than half the analog years. A frequency among named historical years, not a probability from a model, and not a forecast of what the division engineer will do. It says how often years whose flow resembled this one were under a call senior to this right in a given week. Snowpack, storage, and the actual administrative decisions of a given season are not modelled. Check the analog years listed: if they do not resemble this year to you, the outlook does not either.

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: GEORGE RIST DITCH (1861-11-10). Immediately behind: HILLSBOROUGH DITCH (1861-11-10).

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 (24)
| 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 2250.759 cfs decreed rate, the average day over the last 6 year(s) had 433.044 cfs in priority (19% of the decree). No call in effect is a free river — that was 3.8% of days.
On 1718 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 10 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: 3991, of which 2690 sit on a river it flows into.

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.
4332.00000 · never out of priority in these seasons
24286.12023 · peaks at
11 of 11 seasons
46020.24323 · peaks at
11 of 11 seasons
Snow sets the clock here. In the driest third of snow years (3 seasons), 2 seasons stayed under call throughout and 0 ended free. In the middle third (5 seasons), the call settled in for the season around June 10 (June 3 to June 24 across those years); in 2 of them it never lifted at all. In the wettest third (3 seasons), the call settled in for the season around July 8 (June 17 to July 8 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 2 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 10 court cases that also touched 29 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 3 omnibus
adjudications
(CA10077, 104 structures; CA4862, 50 structures; 01CW0182, 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 13,503 AF. Its most recent year on record, 2025, came in at 8,130 AF — 60% 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.
| 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 | Released (AF) | Days recorded | Peak (cfs) |
|---|---|---|---|---|---|
| 2011 | 16,405 | 13th lowest of 15 · 122% of median | — | 95 | 199.0 |
| 2012 | 8,808 | 4th lowest of 15 · 65% of median | — | 113 | 76.8 |
| 2013 | 14,571 | 12th lowest of 15 · 108% of median | — | 142 | 124.0 |
| 2014 | 13,549 | 9th lowest of 15 · 100% of median | — | 124 | 152.0 |
| 2015 | 7,698 | 1st lowest of 15 · 57% of median | — | 81 | 90.6 |
| 2016 | 11,849 | 6th lowest of 15 · 88% of median | — | 125 | 157.0 |
| 2017 | 16,954 | 14th lowest of 15 · 126% of median | — | 135 | 175.9 |
| 2018 | 13,503 | 8th lowest of 15 · 100% of median | — | 127 | 189.0 |
| 2019 | 14,283 | 11th lowest of 15 · 106% of median | — | 135 | 180.0 |
| 2020 | 8,380 | 3rd lowest of 15 · 62% of median | — | 94 | 126.0 |
| 2021 | 17,082 | 15th lowest of 15 · 126% of median | — | 139 | 195.6 |
| 2022 | 14,140 | 10th lowest of 15 · 105% of median | — | 159 | 204.7 |
| 2023 | 9,786 | 5th lowest of 15 · 72% of median | — | 98 | 180.0 |
| 2024 | 12,100 | 7th lowest of 15 · 90% of median | — | 125 | 107.0 |
| 2025 | 8,130 | 2nd lowest of 15 · 60% of median | — | 150 | 54.3 |
Call-derived yield: senior right divertible 100.0% of a median season / 61.2% dry-year.
Trends for this structure
Recorded use shows no clear trend over its last 15 recorded years — which is itself worth knowing.
Its reference gage, Charles Hansen Feeder Canal Wasteway to Big Thompson: 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.
The rubric, component by component
| Check | State | Detail |
|---|---|---|
| identity | complete | name, type, and water source all on file |
| decreed rights | on file | 24 right(s), seniority decoded |
| diversion record | current | 11403 measured days, newest 351 day(s) before the data's end (DWR publishes ~1 year in arrears) |
| record continuity | patchy | 71% of the irrigation seasons in 1950-2025 carry measured days |
| published-record stability | stable | no upstream revisions recorded against this structure |
