I once experienced a storm surge on Lake Superior. I was camped with 
friends on a low beach in a bay in Pukaskwa National Park when a rainstorm 
passed by the mouth of the bay. Suddenly the water rose several inches and 
swirled onto the beach, putting out the fire in the Coleman double-burner 
stove I was cooking dinner on. The water remained high several minutes, 
then slowly drained away. I always assumed that low pressure associated 
with the rainstorm caused the surge. An alternate explanation would be the 
wake from an ore or grain ship that was over the horizon. However, Pukaskwa 
is far from the shipping lanes, so that explanation seems unlikely.
