Picture 1146 makes me laugh. The bottomless looking hole.
It's around 8'
Was getting near bottoming out the backhoe, so maybe a little more.
I checked with that long limb in it, it is about 4-5' of water and 2'+ of really sloppy muck that fell back in

I`m glad the area I selected will be a great pond site, and can't wait to finish out the pond to 10' deep

(then settle w/silt)
