A lodge building at Zaca Lake in the Santa Ynez Valley was destroyed Wednesday night by a fire that spread to the adjacent vegetation and charred 3-5 acres, according to the Santa Barbara County Fire Department.

The blaze, originally reported as a barn fire, broke out at about 5:40 p.m. at the Zaca Lake Retreat, which has 20 lake-side cabins in a remote canyon on the north side of the valley, said Mike Eliason, a Fire Department spokesman.

When a county helicopter arrived on scene, its crew reported that the structure was engulfed in flames, which had sparked into the nearby brush and chaparral.

County crews, assisted by U.S. Forest Service personnel, quickly mobilized to attack the fire from the air and the ground.

With the help of two water-dropping helicopters and two air tankers making retardant drops, firefighters were able to fairly quickly stop the forward progress of the vegetation fire.

“We have fire crews on scene, and they will remain there all night,” Eliason said.

Crews were able to get a containment line around the blaze and were working to extinguish hot spots, Eliason said, adding that they were being hampered by the rugged terrain and falling debris.

Meanwhile, the lodge building was reduced to embers and ashes.

“The large structure is still burning,” Eliason said. “It’s a complete loss, and there is a lot of heat still coming off that structure.”

An investigator was on scene Wednesday night, but the cause of the fire had not been determined, Eliason said.

Nine fire engines were dispatched to the incident, along with two hand crews, bulldozers and water tenders.

Power lines were reported down in the area of the fire.

The Zaca Lake Retreat is perched on the edge of 20-acre Zaca Lake, the only natural lake in Santa Barbara County. It is privately owned and surrounded by Los Padres National Forest.
