How did the duckweed get into your pond?

I don't know. I think maybe ducks, mainly because I see a lot of
them and because of the name, but that's just a guess. I suppose if
alligators and otters can make it here (I'm only a couple of miles
from the Suwannee River) most anything could have brought it.
