Current administration
● In priority — no active call senior to this structure's rights affects its district (23 active call(s) checked).
Which of its rights get called out?
In the 5 past years whose flows most resemble this one (2020, 2024, 2022, 2021, 2025): its one decreed right was out of priority in 12 of the next 12 weeks at least once.

How this outlook is built, and what it is not
Flows at GREEN LAKE SEEPAGE IMPACT POINT around 2026-08-09 (the newest reading on file) sit at 55% of that gage's own median for this window. The 5 most similar past years with a complete administration record (1950–2026) supply the history; each week asks whether a call senior to a given right's admin number was in force that week of the analog year, using the same controlling-call-per-day computation as the Legal tab. Priority is per RIGHT: a structure with several decrees loses its most junior first, and the columns above are the two ends of its range. A frequency among named historical years, not a probability from a model, and not a forecast of what the division engineer will do. It says how often years whose flow resembled this one were under a call senior to this right in a given week. Snowpack, storage, and the actual administrative decisions of a given season are not modelled. Check the analog years listed: if they do not resemble this year to you, the outlook does not either.
Where it sits in line
Priority 1873-05-10 — 81st most senior of the 1815 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: GREEN LAKE RESERVOIR (1873-05-01). Immediately behind: CLEAR LAKE RES (1873-05-10).
On SOUTH CLEAR CREEK at river mile 8.0, it is 1st of 3 down the reach. Nothing modelled upstream of it on this reach. Immediately downstream: CLEAR LAKE RES.
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 |
