The pond is 3/4 or more drained now... we had counted about 15 or so LARGE
frogs a month ago, but I've seen none at all now. (After seeing the snake
with one in his mouth the other day), but it looks like all our fish are
present and accounted for!

Most frogs don't spend a lot of time in water, except during mating season.
Leopard frogs spend so little time in water they're called "Meadow frogs"
in many places.

However, while snakes will eat frogs _and_ fish, they're more likely to go
for frogs when they're available. It's easier for the snake to catch food
on land, and frogs are apt to spend a lot of time immobile, allowing a
snakes to sneak up on them.
