Possibly, but frogs are pretty industrious about hopping around and finding breeding pools. Many species prefer these transient pools where there won't be aquatic predators. I would guess that they can smell water. If you don't see frogs hanging around and signing during the day, tree frogs are a strong possibility.

I'm in North Carolina, and I get both green frogs and grey tree frogs in my pond if I don't have goldfish. The green frogs definitely hang out and sing for mates when there are no goldfish or only young ones, but they go elsewhere when the goldfish are bigger than an inch or two.
