The Knob Fire was reported on Sunday, August 29, 2021 at approximately 2:30 in the afternoon. It began about 3 miles south-southwest of Willow Creek on the Six Rivers National Forest.
By September 1, 2021 the fire was at 1,961 acres and 0% contained. Several areas were under mandatory evacuation orders with other areas under warnings. The forest decided to have the Knob Fire managed by the Incident Management Team working on the Monument Fire.
After work concentrating to get the fire under control, 100% containment was achieved as of the morning of September 12, 2021. Total acreage as of that date was 2,421 acres. All evacuation orders and warnings had been lifted.
The final 209 report was produced the evening of September 14, 2021. The cause of the fire remains undetermined.

The fire is within an area with little documented fire history. Canopy closure is predictably tight. All live
fuels are cured to levels normally seen in late September.
The Knob Fire remains at approximately 2,421 (+0) acres and 100 (+0) percent contained. As of today, Friday, September 24, management of the Knob Fire was returned to the Six Rivers National Forest.
Implement suppression repair on the Knob fire.
|Projected Incident Activity|
Minimal fire. With diurnal nighttime winds and shorter days, fire behavior will temper
considerably under locally "good" relative humidity recovery. Fire behavior will be low
intensity surface fire, interior to control lines on the northern most perimeter. No expansion
expected, as the fire incrementally consumes unburned fuels within containment lines.
Later today we will see a pattern shift, with wind flow becoming more out of the west. Temperatures will be warm again this afternoon. Although we will see a shift to that westerly flow, dry air will remain in place across the fire.
