Matt,

You may be right. However, there are other things to consider. If you have limited rainfall are you going to have enough water to fill the pond? If you are considering runoff to fill the pond, is your watershed the right size? I've seen pond hopefuls with a big, big hole in the ground. It's not a pretty sight.

If pigs could fly bacon would be harder to come by and there would be a lot of damaged trees.
