County fire chief: rapid multi-agency response contained Tabby Mountain fire

Duchesne County's fire chief (identified in the meeting as Josh) briefed the commission on July 7 about the Tabby Mountain fire that began Saturday afternoon and expanded quickly before multi‑agency resources contained it.

"The first call came in... it was already growing from an acre to possibly 5 at that time," the chief said. He credited rapid local response from Tabiona, Fruitland, Duchesne and Altamont fire departments and assistance from federal forestry, the Bureau of Indian Affairs and state resources. Air assets — both a helicopter and a fixed-wing aircraft — were used to drop retardant.

The chief said variable winds complicated the response but at times helped push the fire into itself, which allowed crews to build dozer lines and anchor containment points. A county dozer line helped hold the fire overnight, and a task force crew from Richfield completed mop-up the next morning.

"We ordered up the county's dozer, and that was outstanding response," the chief said. He reported the fire reached a level of 100% containment by the time Federal crews had mopped key areas and that Brandon (a county firefighter assigned as a firefighter-in-charge) would monitor the area for the rest of the week.

Chief Josh warned of thin firefighting personnel and fatigue as the season progresses and said he would keep engines in place while weather risk remains high.

Commissioners thanked the chief and asked about water supplies; he said he would coordinate with the Henefer Water District (named in his remarks as Hana Water District) to assess hydrants and access on affected roads. No cause was determined at the briefing; the chief said investigators were considering human and natural causes and noted extensive fireworks and other human activity in the season as context.

The commission did not take action in response to the update; it served as an informational public-safety briefing.
