River Fire update; firefighters work to reinforce containment lines

September 7, 2019 - 1:52 pm

The River Fire grew to approximately 6,880 acres overnight, with the growth occurring within planned containment lines. Crews were successful in holding the fire between Forest Road 41 and Forest Road 17 on the northeast side of the fire. Crews extended burnout operations along Forest Road 17 back to the southwest on top of New River Mesa.

Today firefighters will work to reinforce containment lines in preparation for thunderstorms which are forecasted for the area on Sunday and Monday.

Though no containment has been reported thus far, many areas on the fire perimeter have not been active for a few days and are unlikely to spread. Due to remote and inaccessible terrain, it is difficult to insert firefighters on the ground to confirm containment in these areas. Firefighters will continue to monitor all areas of the fire from the ground and the air.

To keep firefighters and the public safe, Forest Road 41 (“Table Mesa Road”) is closed from the Tonto National Forest Boundary on the west to the junction with Forest Road 24 (Seven Springs). Additional closures in the area may be required if the fire progresses.
