These booms, which will be placed in the river off Galop Island, in the North Channel, near Johnstown and at Prescott, are chain-and-wood devices used to prevent the build-up of ice during the winter. They ensured an even freeze on the river, helping to improve power generation during the winter months.
All users of the river should take extra care in the narrow reaches where the work is being undertaken to install the booms.
Ice booms are placed in the same narrow reaches of the St. Lawrence River each November before the river freezes over and removed in the Spring when the ice has melted, before the St. Lawrence Seaway shipping season commences.
Ontario Power Generation would like to remind boaters to take every precaution around its dams and generating stations, and to practice safety on Ontario’s waterways.
