Crews working in the steep White River Canyon completed the two remaining segments of fire line around the 570-acre White River Fire on Monday.  The fire line completely encircles the fire and mop-up is proceeding satisfactorily inside the fire line…prompting Incident Commander John Buckman to declare the fire 65 percent contained.   More than 90 firefighters were assigned to night shift…looking to continue mopping up inside the north and south fire lines.  Night shift crews do not work inside the White River Canyon due to safety concerns.  Crews were also adding to or moving existing hose lines so the mop-up operation can proceed deeper into the fire’s interior.   A firefighter working inside the canyon on the fire’s northeast side suffered a heat-related illness during the afternoon and was transported by helicopter to Mid-Columbia Medical Center in The Dalles for treatment.  The firefighter responded quickly to treatment and was released.   As wildfire activity picks up in central Oregon, the incident management team in charge of the White River Fire’s suppression has agreed to support the Oregon Department of Forestry unit in The Dalles with initial attack fire suppression resources should new fires break out inside the unit’s protection area.  Assistance could include engines, helicopters and firefighters to keep newly reported fires from escaping initial attack.
