I would like to weld a rebar

place it on the plant shelf so you couldn't see it really unless you are
right on top of it and the water would
effectively be only 6 inches deep in case one of our grandkids or neighbor
kids fell in.

Actually something that can catch a persons leg is more dangerous. I
had an adult relative die in 1 foot of water because his leg got trapped
and he couldn't get out. When he passed out, he drowned. There is no
substitute for a fence to keep small children out. Then there are nets
that you can suspend just under the water to keep people out and fish
in. It prevents herons from eating all of the fish.
