Where it sits in line
Priority 1872-04-15 — 92nd 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: 0604201 (1872-04-15). Immediately behind: KINNEAR DITCH NO 2 (1872-05-20).
On SOUTH BOULDER CREEK at river mile 16.4, it is 36th of 58 down the reach. Immediately upstream: GREENLEE RES 1. Immediately downstream: HUNTER/HINE 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 (9)
| 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 (7/10 points) — the components below are the finding; the letter alone is not.
The rubric, component by component
| Check | State | Detail |

| decreed rights | on file | 9 right(s), seniority decoded |
| diversion record | fragment | 102 measured day(s) on file (under 180 -- a season, not a history) |
| record continuity | unknown | record too short to assess continuity (needs 2+ years of span and 180+ measured days) |
