As of 3 p.m. Tuesday, Lake Hughes Road was reopened from Ridge Route Road to Deeswood Drive, along with San Francisquito Canyon/Dry Gulch roads to Lake Hughes Road.
However, upper and lower Lake Castaic, along with all Lake Castaic Recreation Areas, will remain closed to support fire operations at the Incident Command Post.
The fire was first reported about 3:30 p.m. Aug. 12 near North Lake Hughes Road and Pine Canyon Road in the Angeles National Forest, according to the Forest Service, which was battling the blaze with the Los Angeles County Fire Department and assistance from other agencies.
“There have been areas of this fire that have not burned in decades, (and) it’s in inaccessible terrain, which has added to the complexity of the fire,” Los Angeles County Fire Department Chief Daryl Osby said at that time.
The Los Angeles County Sheriff’s Department and California Highway Patrol were also involved in the firefight.
Castaic Lake remained closed to public access until further notice. Fire personnel were using the lake and surrounding areas as a base camp.
Gov. Gavin Newsom declared a statewide emergency last week to help ensure resources to combat multiple fires burning across the state.
The cause of the fire remained under investigation.
