On calm days we sometimes see something large swim past my parents camp, going about 1 meter per second, for long straight stretches that can exceed 100 meters. Whatever makes these clearly visible wakes is typically not visible, although sometimes it seems that the back or head breaks the surface. This is one of a series of photos I took from an elevated position on the shore, and by zooming in I can clearly see that it is a large fish. I took the kayak out to see if I could see one up close, or better yet, catch it with my flyrod. I was able to get right in the path of one of these wakes and had a great view of three huge carp swimming right under my boat. There are many accounts on the web of carp cruising the surface of lakes to eat cottonwood seeds, which are extremely abundant on the lake this week. There are even cottonwood flies made specifically for flyfishing for carp (see http://forum.gon.com/showthread.php?p=4852883 and http://coloradoflyfishingreports.blogspot.com/2011/06/carp-on-topwith-cottonwood-seeds.html). I suspect that most of the Lake Champlain Monster sightings are of large carp, singly or in groups. The wakes are visible from a long distance and the waves from the wake can look very serpentine. The size, speed, and energy of these wakes is very impressive. See my video on this page.
