Which of its rights get called out?
Not computable for this structure: no administrative call record for this basin.
Where it sits in line
Priority 1986-04-30 — 1829th 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: SHAW LAKES DIVERSION 2 (1986-04-30). Immediately behind: NORTH SHAW LAKE NO 3 (1986-04-30).
On IDAHO CREEK at river mile 22.0, it is 1st of 7 down the reach. Nothing modelled upstream of it on this reach. Immediately downstream: SHAW LAKES DIVERSION 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 11 years on record)
In a median year this structure has a recorded diversion of 37 AF. Its most recent year on record, 2024, came in at 57 AF — 154% of that, and 10th lowest of the 11 years with a recorded volume.
