I am not a dirt expert in any means but I have a pond like you described down to the ammount of dam there is. Only difference is mine is all dam excpt for the south side. I will say this though if you get it cored get the entire thing done. Mine has no leaks in the long dam part but there is a small leak in one of the side dams near where it comes back and molds into the hill. I have no clue if mine is cored or not though.
