In 1984,I built a dock using treated utility poles on my new 2+ acre pond. I made it in a "U" shape so my boat would be under roof when I docked it.They are still as strong and have never had a problem with any chemicals leaching out of the poles.

Go with the poles,you won't be sorry. You can trust a fellow Kentuckian to speak the truth. Some of these Texan pond owners one can't be too sure about!
