On October 21, the Caldor Fire reached 100 percent containment. Great Basin Incident Management Team 7 took command of the Caldor Fire on Tuesday, October 12. The fire was reported on August 14, 2021 and burned 221,835 acres. With over 400 miles of containment line on the landscape, Team 7 will focus on repair work efforts to remove hazardous trees and slash from high-use areas, clear culverts and repair dozer and hand line to limit potential resource issues. Repair and rehabilitation work related to the Caldor Fire will continue for quite a while. A large number of forest personnel will be tasked with continuing the repair and rehabilitation for the foreseeable future.

The fire will continue to creep and smolder within the fire area long into the winter. The public can expect to see smoke and possible single and/or group tree torching. Other dangers in the fire area include fire weakened hazard trees, heavy fuels that continue to smolder, stump holes, loose rock and debris on steep slopes, and hazmat from burned structures.

 All evacuation orders and warnings have been lifted as of October 4,2021.

KNOW WHERE YOU CAN FLY: Drones pose a serious risk to firefighting and can cause air operations to cease. When drones interfere with firefighting efforts, a wildfire has the potential to grow larger and cause more damage. A FAA Temporary Flight Restriction (TFR) is in effect and any private aircraft or drone that violates the TFR could face serious criminal charges. For more information on drones the public can visit the FAA’s website at “If you fly, we can’t!”

Fuels Involved

Chaparral (6 feet)

Closed Timber Litter

Timber (Litter and Understory)

Fuel is not available over the eastern portion of the fire due to snowfall. Over the western portion of the fire, fuel will not carry fire due to recent rainfall. Surface litter is dry where sun exposure is consistent, but duff and other fuel immediately below the top layer is wet.

Significant Events

Minimal. Smoldering was observed, but instances were rare and smoke volume and activity was light.


Planned Actions

Suppression repair efforts include sustained logging operations for hazard tree removal along roadways, dozer line repair, clearing culverts, and slash removal.

A patrol group will coordinate suppression resource response to service calls and nuisance smoke across the fire area.

Projected Incident Activity

12 hours: Fire will not spread. Smoldering fire activity is not likely to be widely visible.

24 hours: Fire will not move.

48 hours: Fire will not move.

72 hours: Fire will not move.

Anticipated after 72 hours: Fire will not move. Precipitation forecast for Sunday and Monday creates the potential for slides or debris flows where high severity burns and steep slopes are present.

Current Weather

Weather Concerns

SYNOPSIS: A few light rain showers are expected Thursday with a more active weather period starting Friday and through the weekend. Significant rain and higher elevation snow is expected over the weekend with the potential for flooding issues in and around the burn area.

OBSERVED: Gusty south-southwest winds of up to 50 mph along ridgetops were observed this morning with lower winds in valleys and lower elevation areas. Skies were mostly cloudy with a few light showers mainly in the morning. Temperatures climbed into the middle to upper 50s across the area.

FORECASTED: A stronger weather disturbance and cold front will move through the area Friday morning bringing widespread wetting rains. Saturday will be somewhat of a break in the wet pattern with only a few light showers expected. Saturday night into Monday could see significant rainfall of 2 to 5 inches over this time period as a strong atmospheric river event is expected. The heaviest rains are expected Sunday night into early Monday morning increasing burn scar flooding and debris flow potential.
