Took them to a neighbors newly built geo-thermal pond.  He was quite excited.  I'll be bringing a guy in with high lift to rework the inside of the berm.  The neighbors tell me that it was a really nice pond at one time so hopefully there is enough clay in the berm to get it to hold.  The previous owner didn't maintain the pond letting it grow up, so between the rodents and willow trees on the berm it developed several leaks.
