There are no official records of wave height on Lake Champlain. The National Weather Service doesn’t have a data buoy out in the broad lake with which to measure wave heights accurately. It relies on reports from ferry operators to estimate wave heights. The Weather Service says that during Tropical Storm Floyd in 1999 the wave heights may have been up to six feet.
The images below were taken during a storm in February 2006 that had 40mph+ gusts. The waves crashing into the cliff were creating spray all the way to the top of the cliff! It was a wet day on the ferry!
