So I have a layout I would like in my head. 8x10x30" deep. 12"below ground 18" above. I would like to hang a bog on the back of it. I am wanting to use 2x6 for the side boards. Similar to this design.
Does this seem sturdy enough? I am planning on at least two vertical side boards. I would love to avoid rebar but if need be I can swap to 4x4 and rebar. How do I support the bottom of the bog. I would like a 3x8 bog with a foot hanging over pond and how do I make the spillways. Would like to have 2. Thanks for any help as usual.
