Lake Country's fire chief says his crews did everything they could.
At a press conference Sunday evening at the Okanagan Centre fire station, Steve Windsor said Saturday's wildfire "escalated very quickly."
Windsor confirmed eight homes were destroyed by fire on Nighthawk Road and one outbuilding on Tyndall Road. Earlier reports were as many as 10 homes had been lost.
"We did everything possible to save people's homes and property," he said. "We did our best."
He said there is still fire burning below some homes on Nighthawk.
Windsor said all evacuation orders and alerts remain in place, and the fire remains 80 per cent contained.
He said there have been some flare-ups today, and that crews will continue to work round the clock on spot fires.
After the news conference, media are expected to be taken on a bus tour of the fire area.
