Here on the forum we talk a lot about a site being suitable for a pond or lake. However, we always seem to place the most emphasis on soil samples, clay content, watershed....Maybe a potential site can have all the basics covered in good standing and STILL be unsuitable for a pond, due to what lies below.
In this scenario the pond is already in place, and the question becomes one of whether or not to purchase. Granted, the pond was there first, but can "after the fact", off property changes render a previously suitable, existing pond or piece of property, unsuitable? I believe so.
