The fire, which also damaged a barn, has consumed 323 acres since it began Sunday near Lake Oroville. It was about 35 percent surrounded Monday morning.
People living between the middle and southern forks of Lake Oroville were advised to evacuate.
To the south, the fire burning in the mountains near Yosemite National Park also was expected to be fully contained Monday. The fire bordering the western edge of the park was 95 percent contained in the morning.
The Yosemite blaze has burned 53 square miles, destroyed 21 homes and cost an estimated $34.7 million to fight since it was ignited by a target shooter on July 25.
The fire forced hundreds of residents from their houses. All remaining evacuations were lifted, and evacuees were allowed to return to their homes over the weekend.
With several months of the fire season remaining, California already has seen more land ablaze this year -- some 1,975 square miles -- than any since the 1930s when the state began compiling statistics. Fire officials say 25 fires remain active statewide.
