Hi esshup,

Thank you I'll let it go as is for now.

I put a link in the post to a video when I built the deck.
There are 6x6 in the corners on shore then 4, 4x4's pounded into the bottom of the pond about 2' deep. Along with 2 kind of
"T" bars pounded in the pond so the deck couldn't sink.

That's what I came up with at the time.

Thank you again
