eeshup, thanks for the Google map measuring tool, I had no idea there was anything out there that was so easy. As I suspected, the pond is not as large as I once thought, or was told by the good folks that dug it. Only .59 in size. I believe the formula they use when trying to determine acre size for a pond was a more traditional length / width / and average DEPTH, which, if they go by that, even though the surface area never changes, the acre size they say the pond is will grow based on how deep they have dug the pond.

I did google this method back when the pond was dug, and it is a legitimate way to determine acre size, but I don't think it really has that much application for pond owners, since it is possible to have a pond with the same surface area such as mine, but very deep, and a rather false reading of a 1+ acre pond. The problem with that is ( and when we were looking for places to buy seven years ago, we saw places with ponds that were 70 feet deep ! ) from what I understand and even have seen in my small pond to some degree, much of the water in a deep pond goes unused or is unappealing to the fish for various reasons, so the label of a one acre pond would be not be very useful using that method of determining size.

I really like this tool you have passed on to me. I was able to look at our backyard surrounding the pond, which we have long guessed at 5 to 7 acres ( with NO idea at all if we were even close,) and it turns out it is 5.5 acres. Thanks so much!
