We actually have visits from river otters occasionally. They don't "live" in my pond though. They are just passing through. No gators in the pond. It's one thing to have water lilies in 10" of water. It's quite another to have them in 2". That wouldn't even begin to even cover the pot. Actually I have mine growing in plastic milk cartons, cartons that once were used to stack a half dozen, 1/2 gal. glass milk bottles. They are 1' tall and about 18" square.
