Where this page's figures come from

Generated 2026-08-31 16:20 by Hydrohistorian. Sources: DWR HydroBase snapshot HydroBase_CO_20260707 (history) + CDSS REST (current), USGS NWIS cross-checks. Engine v0.5.0 (e1cc9aa) — every figure regenerates from this named code version and data image.

In short

In a median year over its last 8 recorded years it diverts 1,568 acre-feet.

Assembled from the figures on this page — every number above is checked against them before it is shown (2 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.

Source: DWR Dam Safety’s jurisdictional-dam inventory (damsafety/damsafetydaminfojd), refreshed weekly. Joined on this structure’s own WDID as DWR records it on the dam. Hazard class describes the consequence of failure, not the likelihood of it. DWR’s dam record.

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 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 1,568 AF. Its most recent year on record, 2010, came in at 1,420 AF — 90% of that, and 4th lowest of the 8 years with a recorded volume.

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

Year	Diverted (AF)	Compared with its own record	Released (AF)	Days recorded	Peak (cfs)
1998	15,164	8th lowest of 8 · 967% of median	11,652	184	161.2
1999	—	no recorded volume	2,852	0	—

Trends for this structure

Recorded use shows no clear trend over its last 8 recorded years — which is itself worth knowing.

How good is our record of it?

Grade C (4/10 points) — the components below are the finding; the letter alone is not.

The rubric, component by component

Check	State	Detail
identity	partial	missing name, structure type, water source
decreed rights	absent	no water rights cached for this WDID
diversion record	present	653 measured days; currency unknown (no data-coverage date to compare against)
record continuity	sparse	11% of the irrigation seasons in 1984-2012 carry measured days
published-record stability	stable	no upstream revisions recorded against this structure
