RIVERSIDE CANAL ☆ My Water

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.

Zero is a real reading: the gage is reporting, and it says this structure is not diverting right now.

Provisional 15-minute telemetry from RIVCANCO ↗ (RIVERSIDE CANAL AT RESERVOIR INLET GAGE). 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

RIVERSIDE CANAL holds 21 decreed rights on SOUTH PLATTE RIVER. No active call senior to its rights reaches its district today (19 active calls checked), so it is in priority now. 4 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: no administrative call record for this basin. In a median year over its last 15 recorded years it diverts 125,878 acre-feet. It was a party to 16 court cases that also touched 27 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.

Current administration

● In priority — no active call senior to this structure's rights affects its district (19 active call(s) checked).

4 further calls state no district and sit outside this one, so they are counted here rather than assumed either way.

Which of its rights are out of priority?

The outlook for the weeks ahead is not computable for this structure: no administrative call record for this basin. 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.

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 (21)

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 much of this decree was in priority, by day

A right is in priority on a day when it is senior to every call administering this structure. Of its 5834.25 cfs decreed rate, the average day over the last 6 year(s) had 5834.25 cfs in priority (100% of the decree). No call in effect is a free river — that was 100.0% of days.

Calls are set and released at a time of day, not at midnight, so a day is counted by the hour: a call setting at 4pm costs that day a third of its rate, not all of it.

This is paper water. It is the decreed rate that was in priority — not water that was physically in the stream, and not water this structure diverted. A ditch can be in priority for 50 cfs on a day the creek carries five. What that distinction means →

Structures it shares court cases with

This structure was a party to 16 court cases that also touched 27 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.

4 further shared cases not shown — the most specific are listed first, since a case binding two structures says more than one binding a dozen.

Also a party to 6 omnibus adjudications (CA2142, 255 structures; W2919, 144 structures; CA16704, 121 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 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 125,878 AF. Its most recent year on record, 2025, came in at 72,561 AF — 58% of that, and 2nd lowest of the 15 years with a recorded volume.

Trends for this structure

Recorded use shows no clear trend over its last 15 recorded years — which is itself worth knowing.

Its reference gage, Illinois Ditch: no clear flow trend.
