Where it sits in line
Priority 1898-10-01 — 303rd 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: 0600677 (1895-09-30). Immediately behind: HAYDEN LAKE RES (1905-07-21).
On MAINSTEM at river mile 12.1, it is 15th of 78 down the reach. Immediately upstream: PHIL HOGAN SEEPAGE DITCH. Immediately downstream: HARPE SPRING.
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 |
