Six Rivers Lightning Complex
September 26, 2022 UPDATE

The Six Rivers Lightning Complex is currently 41,596 acres with 97% containment and 184 personnel assigned to the incident. Ammon – 11,465 acres; Campbell – 30,128 acres.



Fire activity, in one interior pocket of the Campbell, still has some unburned fuel. This accounts for the 97% overall containment of the fires, which is a result of this one interior pocket of still unburned fuel. This interior pocket is surrounded by already blackened fire area. In addition, the perimeters of both fires have well established control lines around them; resources will continue to patrol and monitor all areas to keep the fires within the current footprint.Warmer and dryer conditions on the fire area today. Warm weather trend will continue through the weekend, with high temperatures rising to or above normal as high pressure builds over the area.Suppression repairs will continue on the Ammon and Campbell fires. Fire weakened trees will continue to pose the greatest hazard in the burn area. The public is cautioned to heed the forest closure orders for this reason. While air quality has returned to normal, you can still monitor the air conditions in your area at the AirNow Fire and Smoke Map - https://fire.airnow.gov .

ROAD CLOSURES Due to a large presence of fire personnel and machinery on roadways, residents are asked to limit travel on Titlow Hill Road/Route 1 in zones HUM-E052 and HUM - E062 to essential traffic only. Residents may still use roads to travel out of evacuation order zones.

Current Situation

Total Personnel
Size (Acres)
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 Outlook

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: Moderate RH values through the evening hours should slow or halt fire growth
24 hours: Cooling temperatures should decrease existing fire behavior, mostly interior smoke from existing heat sources and the interior island. Winds expected to be light.
48 hours: Cooler temperatures and higher RH levels. Hazard trees continue to be a concern on the fire. Road conditions are not expected to effect repair operations.
Box 30 will revert back to old numbers. No structures threatened at this time. Box 32: 7 demobed due to illness; 8 in isolation.

Weather Synopsis

Weather Concerns
Warmer and dryer conditions on the fire area today. Warm weather trend will continue through the weekend, with high temperatures rising to or above normal as high pressure builds over the area.
