Although the Yellowstone River remains the largest undammed river in the continental United States, it is nonetheless exposed to a number of anthropogenic stressors including bank stabilization, diversion dams, water withdrawals, and altered hydrographs, thermographs, and sediment regimes from dammed tributaries. The purpose of this study is to evaluate the effects of bank stabilization on the river morphology, fish habitats, and the fish assemblage within the transition and warmwater fish zones of the Yellowstone River.
