The August Complex is 1,032,649 acres and 93% contained. The fires within the Complex ignited August 16 and 17, 2020. 

Due to the Complex’s size, the incident is divided into two zones and is coordinated between the Mendocino National Forest, Shasta Trinity and Six Rivers National Forests. Incident Management Organization (Coots) is on the South Zone (Mendocino National Forest) and California Team 14 (Strawhun) is on the North Zone (Shasta-Trinity and Six Rivers National Forests). 

In the interest of the safety of firefighters and visitors to the national forests in the Pacific Southwest Region, fire restrictions are extended to November 6 to prevent further fires from being started and overtaxing the resources of those fighting existing wildfires. 

Fire Area Closures remain in effect: 

Private properties accessed via a Forest System road may require a permit from the USDA Forest Service. Please contact the appropriate National Forest office for more information. Hunting and recreation are prohibited within the August Complex Closure area.

Significant Events

Minimal, creeping and smoldering fire activity.

Interior fuels will continue to consume throughout all zones. Seasonal leaf fall and needle cast are leading to isolated, short durations of active fire.


Planned Actions

Northeast Zone: Irish Mountain group will continue to secure fireline into the South Fork of the Trinity River. Monitor the fire within the Buck Fire (2017).

Northwest Zone: Patrol and mop up focused on the Ruth Lake area. Resources continue to

work with homeowners to address concerns and mitigate hazards. Patrol South Zenia, patrol and mop up. Suppression repair in the municipal watersheds of Mad River and South Fork of the Trinity River

is continuing.

South Zone: Monitor through EGP website. Engine crews are cutting hazard trees off National Forest System Roads to improve transportation safety for suppression repair activities.Continue with suppression repair prioritization and implementation along dozer lines. Back haul all unneeded equipment and supplies.

Projected Incident Activity

All Zones: Dry needle cast will fall on burning materials leading to short durations of active burning.

Northeast Zone: Fire activity expected to be limited to current fire perimeter with smoldering and creeping.

Northwest Zone: Minimal fire activity predicted, but there is potential for active fire behavior due to the predicted weather.

South Zone: No perimeter growth expected. Interior fuels will continue to burn out.


Burned acreage as of 10/30/2020:

Mendocino NF-612,634

Six Rivers NF-162,201

Shasta Trinity NF-139,760

West Zone-140,522

Current Weather

Weather Concerns

Seasonably warm and very dry conditions occurred across the fire area once again. Humidity recovery will be best in

the northern portions of the fire and degrade moving to the south. Winds near the surface were once again light and terrain-driven.

The forecast if for temperatures 75-85°F, humidity 15-20%, north northeast wind 6-12 mph.
