I don't think so. I assume your small pond will be made with a liner? That should prevent any disturbance to the roots of the berry plants. The pond will draw birds, so if the berries are intended for you to eat, you might have a problem with the birds getting at them before you have a chance.
I have a small decorative pond right by my front porch, and the birds love it, both summer and winter. Since it rarely freezes here in the winter, it's one of their dependable water sources during periods when we don't get rain.
