Where this page's figures come from

Generated 2026-09-13 17:04 by Hydrohistorian. Sources: DWR HydroBase snapshot HydroBase_CO_20260707 (history) + CDSS REST (current), USGS NWIS cross-checks. Engine v0.5.0 (956f090) — every figure regenerates from this named code version and data image.

In short

In a median year over its last 13 recorded years it diverts 167 acre-feet. That use is rising by about 19.1 acre-feet a year over 13 years (p=0.044083783741320826).

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.

What is in the bundle
  • rights.csv — every decreed right, most senior first, with admin numbers, dates, amounts, uses and case numbers.
  • annual_use.csv — recorded diversion by year, with releases accounted separately.
  • curtailment_now.csv — each right's current priority status and how often it was out across analog years.
  • court_cases.csv — the cases attached to its rights.
  • co_parties.csv — the other structures that were parties to those cases. Not available anywhere else.
  • call_climatology.csv — how often each right has been out of priority by week of season, with confidence intervals and the seasons the record could actually judge.
  • README.txt — provenance, methods, limits, disclaimer, and links back to DWR's own records for verification.

Which of its rights are out of priority?

Not computable for this structure: no decreed right on file, so there is no priority to test.

Recorded use (last 13 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 167 AF. Its most recent year on record, 2024, came in at 335 AF — 201% of that, and 11th lowest of the 13 years with a recorded volume.
