Description: Scope/Content: Abstract: Ecologically based dam removal often seeks to reestablish the pre-dam hydraulic regime of the river, which in turn can significantly affect the timing and peak values of flood hydrographs. As a result, typical dam removal studies address open-water impacts of dam removals. In northern rivers, dam removal and ensuing changes in hydraulic regime cause changes to the ice regime that may have significant local impacts on ice formation, ice cover growth and progression, ice cover breakup, and the movement and jamming of ice. In several cases, dam removal has resulted in increased frequency and severity of downstream jams (Fig. 1). Furthermore, lowering of water levels in impoundments containing sediment deposits may result in more frequent or longer duration ice-induced scour and erosion of bed and bank material. Ice-related adverse effects associated with dam removal can be mitigated through ice control measures.
