The city of Salmon, Idaho, has been affected by flooding resulting from an ice jam on the Salmon River. This ice jam, known as the Deadwater jam, is composed a frazil ice. Environmental and economic constraints require an innovative approach to the control of the frazil ice in this situation. An Ice Control Structure ICS should provide enough control of both production and transport of frazil ice to prevent the Deadwater jam from reaching Salmon. Past investigations have indicated that a temporary ICS, or a combination of temporary and permanent structures, might be successful at Salmon. This interim report documents the progress of a study intended to obtain the information necessary to design an ICS upstream from Salmon. Keywords River ice Flood control Winter flooding.
