OROVILLE, Calif. -

If you saw smoke coming from the Oroville Airport, don't worry. It was all part of a training exercise with a focus on investigation.

With a busy fire season on tap for us this summer, CAL FIRE is taking every chance they can to get ready.

Firefighters pretended it was the real thing Monday morning at the airport lighting 16 vegetation fires in the dry brush fields nearby.

CAL FIRE said the best way to stop wildfires is to know how they get started in the first place.

“The fires are in the middle of the roadways and we have highly trained professionals out here to keep it from spreading,” said Marie Sager with CAL FIRE – Butte County.

CAL FIRE investigators were training more than a dozen firefighters by teaching them the tools of the trade, and how to stop wildfires from getting out of hand.

“The way this season is looking with the hot and dry conditions,” said Sager. “The fuels are thick and ready to burn.”

They were also looking for the tell-tale signs of what starts and fans the flames, things like burn marks and wind direction.

“They get to take the opportunity to practice and train on their suppression skills,” Sager said.

Firefighters used water tenders and water packs to stop the flames from spreading. Fire officials claim one of the leading causes of wildfires are dooryard burns, the burning of yard waste at their homes.

“All it takes is one little spark and the next thing you know it grows to a large fire,” said Sager.

CAL FIRE has issued a burn ban in the unincorporated areas of Butte County. They encourage you to clear all the dry brush around your home and take it to a local landfill just to be on the safe side.
