A vegetation fire that broke out Saturday evening east of Santa Maria blackened an estimated 75 acres, according to the Santa Barbara County Fire Department.
Firefighters responded at about 6:25 p.m. to the blaze along White Rock Road, near Twitchell Reservoir, said fire Capt. Daniel Bertucelli.
A full vegetation fire response — including engines, aerial tankers, bulldozers, hand crews, bulldozers and water tenders — was dispatched to the fire, which had a slow to moderate rate of spread.
No structures were threatened and no injuries were reported, Bertucelli said.
Firefighters from Calfire in San Luis Obispo County assisted in battling the fire.
