That's not a dam. It's a wall of a large tank. I don't think what you are proposing would be practical in an outdoor setting. If you made it work, you would need to set the glass panel in a silicone bed in a concrete wall. The glass would constantly be covered with dirt and algae. If the pond froze, the glass would probably break. Any vandal with a big rock could drain your pond.
