Hi guys I am new here and I was planning to build a 500 gallon pond. My original plan was to build a L6 x W4 X H4 foot wooden frame and drop 2 feet into the ground. So 2ft underground and 2ft above ground.
I had an idea I could save about half the wood buy just digging the 2ft hole and putting a 2ft frame above it instead of a 4ft frame inside of it for preventing caving issues. I saw a video of a guy basically doing this and his pond was still good a year later with no in ground supports like boulders, just a liner and water.
My question is can I dig a 2ft square hole and just put the underlayment and liner in it without having caving issues? The pond will still have the 2ft above ground frame.
