Hi', Frank. That is a very likely explanation, as some snails are air breathers --pulmonates -- and snails, I was once informed, migrate by attaching themselves, by their 'foot', to the surface film, while the surface movement carries them hither and thither, in search of pastures green. The clue is very gentle dimpling, with no sign of a flying or floating insect on or over the water. I associate this behaviour with mid September to October, when there are fewer naturals about. Incidentally, if you are sure that snails are the cause, a fair copy is a fat, short bodied Black and Peacock, with the hackle ginked up.
A dark grey or blue dun hackle works, and you may use a hook with a longer shank to give better point exposure, and to act as a keel.

PS If you can't see your snail fly, you can tie in a bit of material as a marker, pointing forward over the eye of the hook. A bunch of game red cock hackle barbs would do.
