Wildfire near Sugar Pine Reservoir 75 percent contained after growing to 65 acres

A small wildfire that broke out Friday afternoon near the Sugar Pine Reservoir in Placer County was 75 percent contained just before noon Saturday, according to the U.S. Forest Service.

The Sugar Fire burned 65 acres of grass and timber, according to a news release from the U.S. Forest Service.

The U.S. Forest Service led the response effort, with the California Department of Forestry and Fire Protection assisting, said Joe Flannery, a Tahoe National Forest spokesman.

On Friday afternoon, more than 100 personnel were responding to the fire from the three agencies, Flannery said. By noon Saturday, less than 40 personnel remained, including one hand crew, two engines and one water tender, the release said.

Firefighters worked through the night securing securing containment lines and performing mop up duties, the release said.

The cause of the fire is still under investigation, the release said. Sugar Pine Road has reopened to the public.

Cal Fire had earlier tweeted at 8 a.m. Saturday that the fire was 100 percent contained.

The fire is fully encircled with a containment line, which some interpret as 100 percent contained, Flannery said. U.S. Forest Service is estimating 75 percent until the fire is fully mopped up within those lines, Flannery said.

The fire was located at Sugar Pine Road and Big Reservoir Lane, about seven miles northeast of Foresthill and 10 miles east of Colfax. It was the first wildfire in the four-county Sacramento region this year. There have been several other small wildfires in Butte County.
