Firefighters are battling a blaze that is threatening homes at a Northern California lake community that was evacuated because of a destructive wildfire last year.

Daniel Berlant, a spokesman for the California Department of Forestry and Fire Protection, says several streets in Lower Lake are under the evacuation order.

The blaze erupted just before 5 p.m. Saturday and has burned at least 80 acres.

Berlant says firefighters are dropping retardant to protect structures from the flames.

The wildfire is in the rugged hills of Lake County, which was devastated by one of California's most destructive wildfires last September. A CalFire report released this week said the fire, which killed four people and destroyed more than 1,300 homes, was caused by faulty wiring on a hot tub.

5:55 p.m.

A fast-moving wildfire in central California has led to an evacuation order in a lakeside community but it's unknown how many residents left.

The California Department of Forestry and Fire Protection says the blaze broke out shortly after 4 p.m. Saturday in the rolling hills south of Lake Nacimiento, about 230 miles northwest of Los Angeles.

It quickly grew to at least 350 acres and sent a plume of smoke over the lake.

The cause of the fire is under investigation.

Authorities say an evacuation order was issued for residents in the Running Deer Ranch community. It's unclear how many people fled their homes.
