Containment on the Long Bend Fire jumped up to 50 percent late Monday afternoon.  The fire has burned 1,024 acres two miles southwest of Maupin.  The Central Oregon Interagency Agency Dispatch Center says crews were able to make great progress on Monday.  The Wasco County Sheriff’s Office reduced evacuation levels, as south of Highway 216 from Natural Pasture Road to Blue Rock Road, and east of Reservation Road and South of Highway 216 to Natural Pasture Road are now on a Level 1 advisory.  Access to the Deschutes River south of Maupin is expected to reopen on Tuesday.  Boaters should use caution, avoid pulling over on the fire side of the river, and follow directions of firefighters and river staff.  Firefighters on Monday were looking for opportunities to engage the fire directly along Wapinitia Creek, and focused on patrolling and extinguishing sources of heat along the fire perimeter to secure control lines.  Aircraft were assisting ground resources as needed by dropping water to help cool hot spots.  The cause of the fire is under investigation.
