I have 3 of these in my small pond, sized from about 1-1/2" to 4" and I have tentatively identified this one as a green frog. Am I correct?
Also, where do they go in the winter? We have a few inches of muck at the bottom of the pond, which I would like to clean before fall, but I will not if that is where they spend the winter.
Beside the pond are planting beds covered with woodchips and I wonder if they would dig into these areas to hibernate.
The reason I am asking is that we may have some construction (excavation) happening in this area in a few months and I wonder if we shouldn't postpone until early next summer so that the frogs are "awake", back in the pond, and not in the way.
Any advice (and a definitive identification!) will be appreciated. :)

I am located in southwestern PA
