Abstract
During a period of normal low-flow conditions, a major and unusual pulse of suspended sediment was observed in the Middle Fork of the Flathead River, northwest Montana, in late July 1994. Tracing the sediment back to its source revealed that several debris flows resulting from thunderstorms and associated rapid snow melt were the source of the sediment. Although this particular set of events did not produce landslide-dammed lakes, such a hazard exists. The contribution of eastern tributaries to geomorphic change from flooding along the Middle Fork has been considered minor, but this conclusion may require modification in cases of rapid mass movements into their headwaters.
