Where it sits in line
Priority 1860-06-01 — 40th 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: HUNTER/HINE DITCH (1860-05-01). Immediately behind: EGGLESTON NO 1 DITCH (1860-06-01).
On SOUTH BOULDER CREEK at river mile 13.7, it is 20th of 58 down the reach. Immediately upstream: MARSHALL LAKE. Immediately downstream: GOODHUE 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)
| 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 |

Recorded use (last 15 years on record)
In a median year this structure has a recorded diversion of 938 AF. Its most recent year on record, 2025, came in at 689 AF — 74% of that, and 4th lowest of the 15 years with a recorded volume.

How good is our record of it?
Grade B (8/10 points) — the components below are the finding; the letter alone is not.
