Are those railroad ties in that structure? If so, doesn't the creosote affect water quality? I stumbled across part of an old brige buried in my pond site with several large rr ties. I have them piled up waiting to burn, but maybe I should consider putting them in the pond for structure?
They are cedar landscape timbers 6" x 8" left over from a project.
I don't think a few weathered railroad ties would be a problem.
If you want to see what the Xs looked like before they went under water they are in the
