Timber Harvesting and Potential Impacts to the Duhamel Creek Alluvial Fan

In June 2012, the Board received a complaint about Kalesnikoff Lumber Co. Ltd.’s (the licensee) planned road building and harvesting for cutting permit 40 (three cutblocks) in the Duhamel Creek community watershed. The complainant was concerned that harvesting and road building would increase the risk of flooding and debris flows, which could potentially damage property, reduce water quality and endanger the lives of residents of the Duhamel Creek alluvial fan.

Duhamel Creek frequently experiences natural disturbances. The presence and influence of historical landslides and other erosion events are evident throughout the length of Duhamel Creek. The valley sidewalls and streambeds have been eroded over time by events like avalanches, landslides and debris slides. Some of the eroded material was transported downstream, particularly in extreme run-off events, where it settled and created the Duhamel alluvial fan.
