Extreme hydrologic events are becoming more common with changing climatic conditions. Although the impacts of winter and spring floods on lotic ecosystems have been well studied, the effects of summer floods on fish assemblages in mountain streams are less well known. This study took advantage of an extreme precipitation event during the course of an ongoing monitoring program, which allowed the opportunity to quantify the effects of a severe late summer flood on fish communities in a montane watershed. We also evaluated the effect of the flood on the density and age structure of two ecologically important populations of sport fish (brown trout Salmo trutta and rainbow trout Oncorhynchus mykiss).
