Six Rivers Lightning Complex
September 30, 2022 UPDATE 

The Six Rivers Lightning Complex is currently 41,596 acres with 97% containment and 75 personnel assigned to the incident.

Heavy equipment operators, fire crews and patrols are finishing the last projects on the Ammon and Campbell fires. To ensure roadside safety this upcoming winter, crews are currently working to remove trees that pose a potential threat of falling over roadways and critical infrastructure. Pockets of unburned fuel in the interior will continue to smolder and residents may see small smoke outputs. Crews will continue to patrol the fire perimeters. The incident management team have vacated Veterans Park and is back open for the public to enjoy. Some personnel are still occupying the Veterans Hall.

Percent of Perimeter Contained97%
Fuels Involved

Timber (Litter and Understory)

Light Logging Slash

The primary carrier of fire at lower elevations is timber litter with a substantial hardwood dead and down component resulting from winter 2022 ice/snow event. Upper elevations are a timber under story dominated by brush and conifer litter beneath conifer over-story. Overall, these fuel models are well represented by fuel model 165 (very High Load, Dry Climate Timber-Shrub). Fuels to the west become more open and grassy on upper slopes, with heavier conifer component in drainages.

Significant Events

Minimal Creeping, Backing, and Smoldering

Acreage growth is all interior in the unburned islands on the east side of the Campbell fire. These islands, totally approximately 50-acres, have relatively flat terrain with high fuel moistures. The fire is likely to continue to creep along, burning the moist dead ground fuel until a rain event extinguishes them. Fire behavior can be described as smoldering, creeping, and backing with low intensity ground fire.


Planned Actions

Resources will monitor and patrol fire lines, keeping fire in the existing footprint. Roll-out and hazard trees remain an area of concern across the fire and are being addressed where possible. Focus shifts to suppression repair activities working closely with the resource advisors, using available equipment to restore resources to the forest standards. Falling modules continue to work in areas of high safety concern do to snags.

Projected Incident Activity

12 hours: Gusty winds possible tonight over some of the ridgelines. Moderate relative humidity values through the evening hours should slow or halt fire growth

24 hours: Seasonal weather is not expected to effect existing fire behavior. Activity is mostly interior smoke from existing heat source and interior island.

48 hours: Moderate temperatures and seasonal relative humidity levels. Hazard trees still remain a concern on the fire.


Box 30 will revert back to old numbers. No structures threatened at this time. Box 32: 7 demobed due to illness; 8 in isolation.
