Abstract

In August 2003, the McLure forest fire burned 62% of the drainage basin of Fishtrap Creek. The AA. explore the linkages between changes in streamflow, suspended sediment concentration and changes in channel morphology since this fire. Although the short post-fire period (4 years) limits the ability to draw firm conclusions about streamflow changes, there has been no obvious increase in peak flows since the fire. The timing and magnitude of the observed morphologic changes are consistent with the predicted decline in bank strength due to root decay, implying that the observed changes are associated with an internal instability associated with changes to the stream boundaries, rather than with the more typically reported externally driven instabilities caused by changes in streamflow or sediment supply
