EAST RESERVOIR ☆ My Water

The record and the river

Where this structure is measured

A green link is DWR's own: either its telemetry inventory maps this WDID to that station, or the station is named for this WDID (0700553 → 0700553A). An amber one is ours — the station sits within 250 m and shares a distinctive word with this structure's name, which is a strong hint rather than a DWR statement that this gage meters this structure. Wrong? Tell us.

Provisional 15-minute telemetry from 0803406A ↗ (EAST RESERVOIR OUTLET). Raw, not the approved record — it is never merged into the diversion history below. DWR publishes the official diversion record after the water year closes and is approved, which is why that record ends months back while this reads minutes ago.

In short

EAST RESERVOIR holds 16 decreed rights on CLEAR CREEK. A call at CHATFIELD RESERVOIR on SOUTH PLATTE RIVER (1868-03-03) currently reaches it: junior rights called out. 5 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 5 recorded years it diverts 275 acre-feet. It was a party to 6 court cases that also touched 3 other structures.

Assembled from the figures on this page — every number above is checked against them before it is shown (7 checked). The detail, with its method, is in the cards below.

Dam safety

Source: DWR Dam Safety’s jurisdictional-dam inventory (damsafety/damsafetydaminfojd), refreshed weekly. DWR’s record for this dam carries no WDID and no matched NID id, so it is joined by name and position: “EAST” 0.042 mi away. More than half of Colorado’s jurisdictional dams can be reached no other way; judge the match before relying on it. Hazard class describes the consequence of failure, not the likelihood of it. DWR’s dam record.

Current administration

● Junior rights called out — call at CHATFIELD RESERVOIR (SOUTH PLATTE RIVER, priority 1868-03-03).

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.

Decreed rights (16)

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.

How often is it out of priority?

Across the 11 seasons whose call record is complete enough to judge this structure (2016, 2017, 2018, 2019, 2020, 2021, 2022, 2023, 2024, 2025, 2026), week by week from April.

Structures it shares court cases with

This structure was a party to 6 court cases that also touched 3 other structures — changes of water right, augmentation plans, exchanges. Being parties to the same case does not by itself mean water moved between them; which way it ran, and how much, is in the decree.

Also a party to 1 omnibus adjudication (CA60052, 30 structures). Those settled many rights at once and are listed separately: they say these structures were adjudicated together, not that they deal with each other.

Recorded use (last 5 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 275 AF. Its most recent year on record, 2025, came in at 0 AF — 0% of that, and 1st lowest of the 5 years with a recorded volume.

This structure records both diversions and reservoir releases — they are separate water movements and are accounted separately below.

How good is our record of it?

Grade A (9/10 points) — the components below are the finding; the letter alone is not.
