Have you checked the area behind the dam for seepage? Ideal slope for pond slopes is 3-1. So a dam 15 feet tall would be 45 feet wide at the bottom of the slope. That is just one side of the dam. Both sides would equal 30 feet at the base. That would be awesome if you have the room.
Moving lots of dirt gets to be monotonous. I know. Just spent the last 4 days moving dirt and spreading it on the dam for a little more height and width at the top.
