J COOLEY AUG PLAN RECHARGE PIT

Structure dossier · WDID 2002082 · RECHARGE AREA · RIO GRANDE · DWR record

J Cooley Aug Plan Recharge Pit is a water structure on Rio Grande in Colorado. This page is its public record: the water it has a right to, whether it may take it today, and its history, compiled from the Colorado Division of Water Resources.

Where this page's figures come from

Generated 2026-10-14 20:02 by Hydrohistorian. Sources: DWR HydroBase snapshot HydroBase_CO_20260928 (history) + CDSS REST (current), USGS NWIS cross-checks. Engine v0.5.0 (dd58e60) — every figure regenerates from this named code version and data image.

In short

J COOLEY AUG PLAN RECHARGE PIT holds 1 decreed right on RIO GRANDE. A call at CHICAGO D on RIO GRANDE (1881-09-01) currently reaches it: fully called out. 8 further calls state no district and sit outside this one, so they are counted here rather than assumed either way. That is today's position; the weeks ahead cannot be projected for it: this structure is not on the modelled flow network, so no reference gage can honestly stand in for it. In a median year over its last 15 recorded years it diverts 120 acre-feet.

Assembled from the figures on this page — every number above is checked against them before it is shown (5 checked). The detail, with its method, is in the cards below.

Current administration

● Fully called out — call at CHICAGO D (RIO GRANDE, priority 1881-09-01).

Which of its rights are out of priority?

The outlook for the weeks ahead is not computable for this structure: this structure is not on the modelled flow network, so no reference gage can honestly stand in for it. Today’s position is a separate question, and it is answered in Current administration above — that screen reads the district’s active calls and needs no reference gage.

Where it sits in line

Priority 1887-02-09 — 284th most senior of the 8023 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: W2625 WELL NO 07 (1887-01-01). Immediately behind: FARMERS UNION CNL (1887-04-01).

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. Alt-pointAn absolute amount decreed at another structure that may be diverted here instead -- an alternate point of diversion or an exchange. DWR calls this the APEX amount; a right showing 0.0 absolute but an alt-point amount is exercised here under another structure's decree. Decreed forWhat the court said this water may be used for -- irrigation, municipal supply, augmentation and so on.Case
13554.00000 1887-02-092000-12-29 120.0 AF 0.0 — Recharge 00CW0042

Amounts marked cfs are flow rates; AF are stored volumes (storage rights are decreed in acre-feet). An absolute amount of 0.0 beside an alt-point amount is not a dead right: the water is decreed at another structure, and that row records permission to divert it here instead (an alternate point or exchange). A case listing several numbers reflects the original decree plus later change cases.

Recorded use (last 15 years on record)

Years far under the decreed amount? That gap has a name — paper water vs. wet water, explained on this structure.

In a median year this structure has a recorded diversion of 120 AF. Its most recent year on record, 2025, came in at 60 AF — 50% of that, and 3rd lowest of the 15 years with a recorded volume.
