Screen capture of the Persistent Ice Hazard map around the Champlain Bridge.
Some types of hazards occur in the same place year after year. Gas, current and reef holes are good examples. We have started a map which has a fair amount of data for some parts of Lake Champlain. The map is most useful for checking out an area to learn of some of the problems you might find there. As always, expect to find hazards not shown on the map.
