On August 14, 2021, the Tremont Creek wildfire threatened the community of Logan Lake, British Columbia, when the high-intensity wildfire approached from the north. A wind shift mid-afternoon on August 14 pushed the fire head toward the east with flanking fire spreading toward Logan Lake. Late in the afternoon, extensive aerial suppression operations were
conducted to reinforce forest fuel reduction treatment areas on three sides of the community. Later in the evening, suppression crews incorporated fuel treatments in a successful burnout operation to reinforce a control line that had been created by heavy equipment and hand crews.
This case study presents the fire chronology with fuel, weather, and topographic conditions that impacted fire behaviour. A key objective of this case study is to examine how fuel treatments modified fire behaviour or were strategically used to support and enhance suppression operations.
