ICE AND SHIP EFFECTS ON THE ST. MARYS RIVER ICE BOOMS

The operation of ships in winter under a federal program to extend the navigation season on the river has led to troublesome ice movements and accumulations. To help counteract these effects, two ice booms with a 250 ft (76 m) wide navigation opening between their adjacent ends were installed at the southerly outlet from the harbor at Sault Ste. Marie, Michigan and Ontario. The ice booms contained six force measuring devices. Records of these forces and pertinent data on the weather, water levels, ship passages and ice conditions were kept the following winter of 1975-76. The ice booms reduced the harbor ice losses to an acceptable level and provided much information about the interactions between itself and the ice cover and the ships. Ships and environmental effects kept the ice behind the west boom free from shore much of the winter.
