St. Lawrence River<\/h3>\n

The U.S. Great Lakes St. Lawrence Seaway Development Corporation maintains 99 lighted buoys and 112 fixed aids in the U. S. Section of the St. Lawrence River. These aids to navigation are commissioned in late March as ice conditions permit. They are decommissioned in mid to late December during Seaway closing activities.<\/p>\n

The Chief, Marine Services Division, prepares a commissioning\/decommissioning schedule based on ice\/weather forecasts and traffic demands.<\/p>\n

All Canadian aids to navigation are managed by the Canadian Coast Guard and follow approximately the same schedule.<\/p>\n
