Horsefly -

The Horsefly Fire became active on August 6, 2019, and within 24 hours had grown to 1274 acres. It is situated in densely timbered steep terrain with a heavy load of beetle killed fuels, southwest and east of Lincoln, Montana. While fire activity has decreased significantly, fire spread is still possible. Fuels continue to smolder, although visible spots of smoke have been rarely observed in the past 24 hours. Shane Martin’s Central Montana Type 3 Incident Management Team remains in command of this incident.

Horsefly Fire Size: Approximately 1,350 acres Containment: 55% Cause: Unknown Location: 15 miles east of Lincoln Structures destroyed: 0 Fire updates are now posted every 48 hours unless there are significant changes. The Incident Command Post moved to Lincoln, MT, and is operating from the Lincoln Ranger District effective 8:00 am, August 18th. Heavy equipment crews began a check line from the fire’s Northeastern perimeter toward MT Highway 279. This check line will give firefighters a safe point to engage the fire should activity increase with our warmer forecasted weather. Once this check line is complete, fire managers will assess to see if an additional check line should be constructed off the fire’s Northcentral perimeter toward MT Highway 279 to reinforce defensible line if fire activity increases. Two fire crews will continue to patrol the fire perimeter, engage hotspots where exposure is minimized, and mop-up containment lines. Firefighter and public safety remain the number one priority in wildland fire suppression efforts.
