The Caldwell Fire in northeast California was not as active Tuesday as it had been in recent days. It added an additional 1,508 acres which brought the total up to 69,297. Most of the growth was on the northwest side within or west of Lava Beds National Monument.

The area is under a Red Flag Warning Wednesday from 2 p.m. until 8 p.m.

From the Incident Management Team, July 29, 2020:

“[Tuesday] crews conducted burning operations to even out the fire’s edge and fill in unburned areas. On the west side of the fire, the 49 road is holding well. Firefighters were able to begin direct control line construction on the south side of the fire, working from the 49 road eastward. Additionally, crews are still creating secondary control lines south of the fire perimeter.

“On the southeast corner, dozers and firefighters succeeded in creating solid control line, and this allowed the residents of Tionesta to return to their homes. On the east side, fire held well along the 120 road, and fire crews built control line all around the fire area that had crossed over the railroad tracks. On the north, fire flanked into the marsh and the tule is receptive to burning, however, fire is holding well at the 120 road.”

The fire has spread to approximately one mile south of County Road 120. Firefighting resources attacking the new growth included 20 engines, 5 water tenders, and 3 20-person hand crews. On the east side firefighters stopped the fire along 6 miles of a railroad, however there was one slop-over.
