Devil’s Knob Complex Update
Sunday, September 12, 2021 – 9:00 a.m.
Rocky Mountain Type 1 Incident Management Team
Dan Dallas, Incident Commander
Information phone: 541-900-6133
Information staffing hours: 8:00 am – 8:00 pm
The cooperative weather of the last two days allowed fire managers to modify containment strategies in Divisions G and A on the north side and adopt a smaller footprint. Indirect line preparation continues as a contingency and will provide additional defense should fire move out of primary lines. The high humidity, cool temperatures, and calm winds diminished flame heights and fire spread enabling firefighters to work directly on the edge. Despite calmer fire behavior, several spot fires were detected yesterday. Firefighters were aggressive in their response and placed fireline around the spot fires.
Today, skies will be clear of smoke and clouds which will impact fire behavior, promoting burning activity on south and southwestern facing slopes due to solar heating of fuels. Weather will also be warm with average temperatures in the mid 70s and humidity about 40%, contributing to an uptick in fire behavior with fire activity starting earlier in the day. Fire behavior is not anticipated to be as active as early last week. With the clear conditions, crews will be supported by helicopters allowing for continued efforts on building line on uncontained edges, completing firing operations where feasible, and further securing contained perimeters.
Acreage: 44,410 | Containment: 20%
Branch I: Divisions E and F – Firefighters will continue patrol and mop-up.
Division A and G – Across Divisions A and G, firefighters observed slow-moving fire due to the moist conditions. With the clear skies, helicopters were able to fly and three additional spot fires in the vicinity of Hemlock Lake were discovered. Firefighters worked to place fireline around the spots and will continue to secure spots today. In Division G, firefighters continued work on direct firelines and indirect firelines along Forest Road 2719.
Branch II: Division B – Heavy equipment and chippers aided firefighters by helping to dispose of fuel east of Ash Valley. Removal of this vegetation would diminish fire behavior should winds shift and fire threaten structures from the east. Other work remains unchanged from yesterday; firefighters will continue preparations along Highway 28 and firelines will continue to be secured around structures.
Divisions C and E – Today’s work will include patrol, mop-up, and securing of contained firelines, construction of uncontained firelines and assessing options for the uncontained finger near Ash Flat Campground.
Big Hamlin Fire
Acreage: 19,035 | Containment: 75%
Branch III: Divisions J, L, and N – Firefighters will continue holding the fire in its current footprint through patrol and mop-up efforts.
Divisions H – Yesterday, firefighters were moderately successful in introducing fire to Division H, but moist fuel conditions limited fire from establishing and carrying. Today, firefighters will be using fire as a tool again, and may be aided by a helicopter conducting aerial ignitions. Firefighters will also be supported by a crew of fallers removing standing dead trees and other trees that present hazards to firefighters or which could fall on Forest Roads 29 or 2925.
Weather and Fuel Conditions:
Sunny skies with little smoke and dry air are predicted for today. Temperatures will range from 70 to 80 degrees, depending on elevation, and humidity will average about 30%. These conditions will drive more active fire behavior with increased tree torching and the possibility of fire spread. Areas with heavy dead and downed trees will experience the most fire activity.
The Ash Creek-South Umpqua Road remains at a Level 3: Go (Leave immediately). As of 8 am on September 11, Dumont 2810 to Jackson Creek was reduced to Level 1: Be Ready.
