Hello everyone, I want to build a 8x20 KOI mud pond in my backyard without using liner. Ground water is within 3 feet of the ground surface (I do have a 8x11 pond with liner right now so I know and there is a natural pond for the goft course about 50 yards away in the back of my house that has clean and high water year round.
I don't know anything else about mud/natural pond.
I guess maybe I want to know how deep do I have to dig to bring the water level up near to the ground level?
Your help is much appreciated.
