Commissioners report continued debate over Tropic Reservoir releases and leaky head gate; metering study planned

Garfield County commissioners discussed ongoing water-management issues for Tropic Reservoir and area irrigation systems, describing technical and institutional barriers to storing and delivering water across a long, arid reach.

Commissioners said the reservoir’s existing gate leaks an estimated 3–4 cubic feet per second and that the state engineer and irrigation companies plan to install metering devices this winter to measure actual flow and how far the water travels. County officials expressed skepticism that releases will reach downstream destinations more than 30 miles away and said winter metering data will inform future decisions.

Officials said the state engineer has required a 10% release in recent years, a change they described as reducing the East Fork Irrigation Company’s ability to store. County leaders said the state previously told commissioners that restoring an earlier agreement would allow storage again, but that the change in engineering requirements and interagency decisions have complicated the situation.

Why it matters: Water allocation, storage and conveyance affect local farms, ranches and communities across long distances in Garfield County. Commissioners said the metering effort will provide data to evaluate whether stored water reaches targeted areas and whether state-level agreements should be reinstated or renegotiated.

What was not decided: No formal county action or appropriation was recorded; commissioners said they would coordinate with the state engineer and irrigation companies on the metering study and follow up with staff.

Ending: Commissioners said the winter’s metering data should clarify whether existing releases produce meaningful downstream benefits and whether longer-term infrastructure or agreement changes are required.
