Firefighters have increased containment to 60% on the 1,024-acre Long Bend Fire.   The fire is located approximately two miles southwest of Maupin on the west side of the Deschutes River.  Firefighters continue to identify and extinguish sources of heat within the fire perimeter to further secure control lines.  Most of the remaining heat is still along Wapinitia Creek so crews and aircraft were focusing their efforts in that area again today.  Crews will also continue to patrol the flanks of the fire that are contained to ensure the fire stays within the established containment lines.  A Central Oregon Type 3 Incident Management Team will transition command of the fire scene to a Type 4 Incident Commander at 6 a.m. tomorrow.  The fire started the afternoon of Saturday, June 22.  The cause of the fire remains under investigation.
