800-Acre Brush Fire Near Castaic Lake 20 Percent Contained

A 800-acre brush fire continued burning near Castaic Lake for the second day Sunday as containment reached 20 percent, officials said.

Crews were tackling the flames at the fire's east end after focusing more on the western portion after it broke out around 2 p.m. Saturday, according to Nathan Judy with the U.S. Forest Service.

The fire reached 1,000 acres at its peak and firefighters were hoping the push the fire down toward the lake itself.

However, the lake was expected to remain open to recreational boats Sunday via the western ramps, officials said. No roads closures were reported.

No homes were threatened, but two outbuildings were destroyed the previous day, officials said.

One minor laceration injury occurred Sunday, according to the U.S. Forest Service's incident information page, but it was unclear whether the person injured was a firefighter or civilian.

More than 450 firefighters were on scene battling the blaze, along with nine aircrafts.

The crew prepared for the triple-digit heat expected in the area on Sunday, Judy said.

“It does make it more difficult," he told KTLA. "It’s the hydration issue we’re concerned with.”

Wind would also likely be a factor but wasn't a large concern, Judy said, with gusts predicted to be coming from south and southwest at around 4 to 8 mph.

Tall grass surrounding the lake had fueled the flames Saturday, contributing to its rapid expansion.

The cause of the fire was unknown, but officials said they were looking into campers who were in the area.

It is the second fire in the area this month after a 25-acre blaze broke out near the 5 Freeway at Lake Hughes Road on June 3.

A second Southern California fire that was burning Saturday in Wrightwood, in San Bernardino County, was held at 11 acres on Sunday, firefighters said. Containment was at 50 percent Sunday, compared to 20 percent the day before.

Although some resident were ordered to evacuate Saturday afternoon, they were able to return to their homes by evening.
