Summary: Southwest Area Incident Management Team #3 is utilizing a full suppression strategy and developing tactics that minimize impacts to important values at risk. Firefighter and public safety remain the highest priority.

The Terwilliger fire has established on both the west and east sides of Cougar Reservoir. To the west near Terwilliger (Cougar) Hot Springs and across the reservoir to the east in the Three Sisters Wilderness. Wednesday morning crews went direct on the western portion of the fire. When the smoke inversion lifted and winds increased, fire became very active and moved to the west across Forest Road 115 and north of Boone Creek. Crews disengaged from the line and began scouting for new line locations as fire activity continued well into the evening. The eastern portion of the fire moved to the east toward Tipsoo Butte within the Three Sisters Wilderness. Resources assigned to the Terwilliger fire assisted with a new start at the request of Oregon Department of Forestry.

Firefighters will resume direct line construction Thursday from Forest Road 19 west to hold the fire north of Forest Road 266 and east of the Forest boundary, minimizing impacts to private lands to the west. Heavy equipment will continue to open existing roads and fire managers will scout out areas with the highest probability of success to hold the fire on the west and northeast sides of the fire. 

The fire did burn through Terwilliger (Cougar) Hot Springs. Damage assessments will begin as soon as it is safe to enter the area.
