HOMESTAKE TUNNEL OUTLET

Structure dossier · WDID 1104614 · DITCH · LAKE FORK · DWR record

Homestake Tunnel Outlet is a ditch on Lake Fork in Colorado. This page is its public record: the water it has a right to, whether it may take it today, and its history, compiled from the Colorado Division of Water Resources.

Where this page's figures come from

Generated 2026-10-17 07:13 by Hydrohistorian. Sources: DWR HydroBase snapshot HydroBase_CO_20260928 (history) + CDSS REST (current), USGS NWIS cross-checks. Engine v0.5.0 (dd58e60) — every figure regenerates from this named code version and data image.

Who owns it

DWR’s own records name no owner for a ditch, reservoir or well, so this comes from the source shown and can be out of date. Organisations only: a private landowner’s name is never listed.

The record and the river

This is water crossing the divide

Homestake Tunnel Outlet is the receiving end of the Homestake Tunnel (tunnel). It takes water from Homestake Creek, Eagle River basin (Div 5) and delivers it to Turquoise Lake, Arkansas River basin (Div 2). Water arriving here is an import: it was never in this basin’s own runoff.

The other end: Homestake Proj Tunnel 3704614

Metered as a facility: HOMTUNCO — the record for the crossing itself, which may run longer than the record for either structure.

Owner / operator: Colorado Springs Utilities / Aurora Water

In short

In a median year over its last 12 recorded years it diverts 24,288 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.

Which of its rights are out of priority?

The outlook for the weeks ahead is not computable for this structure: no decreed right on file, so there is no priority to test.

Recorded use (last 12 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 24,288 AF. Its most recent year on record, 1986, came in at 17,715 AF — 73% of that, and 4th lowest of the 12 years with a recorded volume.
