Firefighters have decided to use a bold tactic to stop the northern spread of the Carr Fire in California. Since it started from a burning vehicle near Redding on July 23 it has burned over 186,000 acres in an area about 27 miles long by 19 miles wide.

The tactic they selected a couple of days ago was to go approximately five miles north of the fire and backfire, igniting ahead of the main fire hoping that eliminating burnable fuel will stop the main fire when it reaches the backfire. This is taking place along a 12-mile stretch at the northwest part of Shasta Lake near Moist Cove working to the northwest, roughly following Road N7601 and dozer lines they are constructing. Then they make a left turn south for another five miles to tie in with the main fire east of Trinity Lake.

If crews can get the backfire to consume the fuel for at least several hundred yards (more is better) toward the main fire, they will have a pretty good chance of success.

Backing off from the fire, WAY OFF, and removing the fuel by burning it, usually from a ridge, has often worked very well. Sometimes firefighters ignite a backfire from the next ridge ahead of the fire, which may not provide enough time to complete it to the point where it will be effective. The late Rick Gale, who over several decades fought some of the largest wildland fires as a Type 1 Incident Commander and Area Commander, would say, “Don’t choose the NEXT RIDGE, choose the BEST RIDGE”, even if it is miles away.

If the north end does not move any further, the backfire would encompass approximately 40,000 acres, roughly 12 miles by 5 miles in size.

The Carr Fire has been spreading more slowly in recent days. It has been fairly quiet around Redding, but has continued to grow on the northeast and southwest sides.

Resources assigned to the fire include 335 fire engines, 76 hand crews, 12 helicopters, 112 dozers, and 125 water tenders for a total of 4,665 personnel.

According to CAL FIRE, 1,077 residences and 22 commercial structures have been destroyed in the fire. Three people working on the fire have been killed, including two firefighters and one CAL FIRE heavy equipment mechanic.

A Red Flag Warning is in effect Saturday for high temperatures, low humidity, and gusty winds.
