FORT COLLINS - The Galena Fire is expected to be 75 percent contained tonight, at the end of Sunday's operations, according to the Larimer County Sheriff's Office.

Officials say there was minimal perimeter growth Sunday. However, authorities say the total acreage will likely be higher than previously reported. The total acreage burned will be available on Monday.

Firefighters worked against gusty winds to contain the wildfire that has scorched an estimated 750 to 1,000 acres in the foothills west of Fort Collins.

Calm weather Saturday allowed crews to make significant progress. The National Weather Service was worried about winds on Sunday, but says wet weather prevented the fire from growing.

A Type III fire incident management team is battling the fire with the help of additional crews and a Type 2 helicopter. A second helicopter was ordered for Sunday.

The fire, reported Friday morning, forced hundreds of residents from their homes. All evacuees were allowed to return home Saturday night, but they have been told to remain prepared to leave again.

The blaze is burning west of Horsetooth Reservoir, near the scene of a large wildfire last summer that burned 259 homes and killed one person. No injuries have been reported and no structures have been damaged in the latest fire.

South Bay, Inlet Bay, Lory State Park and Horsetooth Mountain Park remain closed.
