The purpose of this report was to evaluate the hydraulic characteristics of mudflow events resulting from a hypothetical failure of Castle Lake a debris blockage on the north fork of the Toutle River, caused by the Mount St. Helens eruption on 18 May 1980 and to examine the ability of a downstream sediment retention structure SRS to capture and pass such events through an emergency spillway. mm
