Which of its rights are out of priority?
Not computable for this structure: no gage record for this year at this date, so there is nothing to find analogs for.
Where it sits in line
Priority 1884-07-03 — 688th 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: ZILLIGEN & COUCH DITCH (1881-12-31). Immediately behind: 0700859 (1884-07-03).
On RALSTON CREEK at river mile 26.7, it is 1st of 24 down the reach. Nothing modelled upstream of it on this reach. Immediately downstream: SEA OF STORMS 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 (5)
| 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 |

Trends for this structure
Recorded use shows no clear trend over its last 13 recorded years — which is itself worth knowing.
Its reference gage, RALSTON-CLEAR CREEK CANAL: no clear flow trend.
How good is our record of it?
Grade A (10/10 points) — the components below are the finding; the letter alone is not.
