16% of normal flow, week of 2026-09-21
0 calls the record places on it, 7 unsettled

The South Platte River is critically low for late September -- 16% of normal flow. No call that the record places on it is active right now. DWR's statements do not settle whether 7 more calls reach it.

Call cascade

If a call were placed at a given seniority, which structures in this basin would be out of priority, and how much of their decreed rate would be curtailed? Computed from this basin's cached decrees.

What this does and doesn't model. Seniority arithmetic only: every right junior to the call is treated as curtailed. It does not model reach applicability — structures downstream of the calling point are not administered by it — and it applies no futile-call judgment. Read it as “who is junior to this date, and by how much,” not as a prediction of what the Division Engineer would actually order.

Pick a calling right

Real decrees from this basin, ordered by administration number — that is, by actual seniority. The years will look out of order, and that is correct: an administration number encodes the adjudication date as well as the appropriation date, so a right appropriated in 1970 can be administered ahead of one from 1950. A senior call curtails almost everything; a junior one curtails almost nothing.

Or enter an administration number directly

DWR administration numbers encode appropriation and adjudication dates; lower is more senior.

Topology cross-check: 9 parent disagreements, 8 sizable streams not on this network (vs DWR's route framework — under review)

This flow network was built mechanically; DWR's Source Water Route Framework disagrees with it in the places below. Each row is a question a human reviewer has not yet answered — not an error verdict. Checked 22 streams, 13 agree. Know this water? Tell us →
