Where it sits in line
Priority 1859-10-01 — 4th 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: LEYNER COTTONWOOD DITCH (1859-10-01). Immediately behind: DRY CREEK NO 2 DITCH (1859-10-01).
On SOUTH BOULDER CREEK at river mile 10.6, it is 12th of 58 down the reach. Immediately upstream: COMMUNITY DITCH. Immediately downstream: LAFAYETTE DITCH NO 9.
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 (23)
| 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. | Units | UsesWhat the court said this water may be used for -- irrigation, municipal supply, augmentation and so on. | Case |

How good is our record of it?
Grade B (8/10 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 | 23 right(s), seniority decoded |
| diversion record | current | 3689 measured days, newest 399 day(s) before the data's end (DWR publishes ~1 year in arrears) |
| record continuity | sparse | 23% of the irrigation seasons in 1950-2025 carry measured days |
| published-record stability | stable | no upstream revisions recorded against this structure |
