Fire teams have managed to bring the Little Bobtail Lake fire about 80 per cent under control, though about 80 people remain forced from their homes.
The province's Wildfire Management Branch says cooler, wet weather has helped with firefighting efforts, which are focused about 70 kilometres southwest of Prince George, B.C.
About 220 fire personnel are still on the scene, with many involved in what the branch describes as aggressive mop-up and patrol efforts.
The blaze has not grown since it spiked more than 40 per cent a week ago, from 170 square kilometres to 250 square kilometres.
An officer with the province's fire branch has raised concerns about such a large wildfire striking so early in the 2015 fire season.
