Blanket Creek and Spruce Lake Fire Update: August 3

Release Date: Aug 3, 2017  

Contact(s): 541-560-3359

Blanket Creek and Spruce Lake Fire control operations continue with ongoing challenges of record heat and extremely dry fuels.  Each day, in the afternoon heat, the fires have increased in intensity.

Tuesday evening, the Blanket Creek Fire spotted several times north across the containment line into the Lick Creek drainage.  Although some spots were contained, fire became established on a steep hillside.  Preparations have begun to secure an alternate series of containment lines that include Road 6215 (Ginko Rd) and dozer lines parallel to Road 100 that will enclose this portion of the drainage.  The Oregon Department of Forestry is preparing contingency lines to prevent potential spread onto private land west of the fire. Water dropped by helicopters slowed fire movement to provide additional time to initiate this work.

On the northeast flank, burnout operations continued to reduce fuels and reinforce containment lines in advance of the fire.

Last night, on the south edge, a small slop-over occurred across Road 6205.  Crews continued to hold the remaining southern fireline along nearly 8 miles of road. Today’s high priority is to secure the slop-over.

The Spruce Lake Fire continued to grow from the western side of Crater Lake National Park.  Embers flew eastward, up to a mile at a time, starting new fires that then grew together and spotted ahead again.  The fire has now crossed the Pacific Crest Trail (PCT). The PCT is closed for approximately 8 miles, from the intersection of Lightning Springs Trail north to Red Cone Camp. Crews will continue to aggressively suppress this fire, working from the rear and along the flanks to hold established fireline and protect commercial timber to the south and west.  The Spruce Lake Fire is expected to continue to spread eastward today and be confined by natural barriers such as wetlands and previous fires.

As this week’s record breaking temperatures continue, crews remain on high alert for heightened fire activity and personal safety.  Excellent training, physical fitness, and situational awareness help decrease the dangers faced on the fire line but heavy exertion in such abnormally high temperatures continues to present safety concerns.

The Blanket Creek and Spruce Lake Incident Command Post and fire camp are located in the Day Use area of the Joseph Stewart State Park on Lost Creek Lake near Prospect, Oregon. The marina, campground and local businesses are open for visitors while the fire camp is nearby.
