I have ponds. I have two 35 gallons one of those is one of those patio ponds about 14 inches high and 30 around. It is made to be above ground but mine is not on the patio, it is in the shrubs that make a woodsey area along my south side fenceline. Then my other 35 gallon is inground about 12 inches deep and 3 feet around. I usually get a frog or two in that pond in the summer. Plus my "big" pond is a 350 gallon livestock stocktank. It is in ground and has rocks around it to make it look very natural in the garden. That is the one I have nicer fish in since the racoons can't get them. It gets a frog or two come summer also. But toads, I have a heavily mulched garden but no toads that I can see. Believe me if one could buy north american toads in the pet store, I would buy them.
