Hi, we are building a pond new pond using a on a sloping site. The higher end will sit approx 12" higher than the lower end. The site is now level.

@poconojoe I'm willing to bet when they talk about a porous wall between the bog and pond is due to the make the bog in the pond and separate them by only a porous wall like wood or cinderblock. If i was to build such a set up i would install liner between the peastone and the block wall to insure no large flows get through without being filtered
