Perimeter of the Bush Creek East fire (map data)

The Bush Creek East fire was a wildfire in the Canadian province of British Columbia. The fire caused a major loss of structures and forced the evacuation of thousands of residents. The communities of Squilax, Lee Creek, Adams Lake, Scotch Creek, and Celista were heavily impacted by the fire. The fire was listed as "being held" in September 2023 at a size of 45,613 hectares (112,710 acres), and was declared out in December of 2023.[1]

Background

[edit]

Western Canada has seen a climate change-induced warming and drying trend since the mid-2000s. The province of B.C. experienced major fire seasons in 2017, 2018, and 2021, with burned areas far exceeding yearly averages.[2] Much of the province went into 2023 in drought conditions made worse by a hot, dry fall season in 2022 and lower than average snowfall over the winter. The Shuswap and Okanagan regions saw average temperatures of 2 degrees Celsius above normal during the summer, with extremely low amounts of precipitation.[3]

Ignition

[edit]

The conflagration started as two separate fires, first detected on July 12, 2023. The first, Bush Creek East, started on a ridge near Bush Creek between Adams Lake and Sun Peaks to the west. The second, called Lower Adams Lake East, started on the steep eastern shores of Adams Lake. Both were assessed to by caused by lightning, the result of a series of thunderstorms that passed over the area on July 11 and 12.[4]

Spread and structure loss

[edit]
A pyrocumulus cloud forms over the North Shuswap area during the August expansion of the fire.

The two fires experienced moderate spread for over a month, before spreading rapidly on August 19 and 20. A cold front caused strong 40 km/h winds from the north, causing a massive fire expansion. BC Wildfire officers reported a 20 km growth of the perimeter in 12 hours, a rate of growth "unheard of in B.C. wildfire activity".[5] The expanded fire destroyed 270 structures in the North Shuswap area, with severe damages to the Little Shuswap Band, Scotch Creek, and Celista communities.[6] 3500 properties were placed under evacuation orders.[6] 174 buildings were lost in the Columbia-Shuswap Regional District, 9 in the Thompson-Nicola Regional District, and 85 in the Skwlax First Nation.[7] The fire caused over 240 million Canadian dollars in insured damage.[6]
