Following the 2021 Two Mile Road Wildfire, the Columbia-Shuswap Regional District retained BGC Engineering Inc. to complete a hazard assessment in the areas impacted. In its Assessment Report, BGC identified the risk of a post-wildfire debris flow.
The fire affected Wiseman Creek, which flows onto the Sicamous Creek fan-delta complex and is located immediately south of the town of Sicamous. This fan-delta complex is composed of sediments of Sicamous Creek, Wiseman Creek and a small unnamed creek south of Wiseman Creek.
This work was commissioned following a separate hazard assessment for Sicamous Creek currently being completed by BGC for the Fraser Basin Council (FBC). During fieldwork for FBC, Wiseman Creek watershed was identified by BGC as being prone to post-wildfire debris flows.
