Containment of the County Line 2 Fire on the Warm Springs Reservation is up to 31 percent.  That fire has burned 61,735 acres.  As of Tuesday morning, all Warm Springs Reservation evacuation advisories were reduced to Level 1 except for Tenino Road, which remains at Level 2 from mile post 1 to mile post 7.  Crews today will continue with structural protection and direct and indirect line construction, and strengthening containment lines.   Firefighters continue to look for opportunities to build containment lines in the steep, tough to access terrain in canyon bottoms and proceed with operations in those areas if possible.  Because of progress made on the northeast and east sides of the fire, crews will begin to concentrate on the southwest, which still has heavy fuels including timber.  On the northeast side of the fire, crews are patrolling burned areas in and around structures.  Three residences have been reported destroyed along with one other structure.  The cause of the fire reported Wednesday afternoon remains under investigation.
