Pond Boss Forums POND CONSTRUCTION Creating habitat Setting posts for a non floating dock

We have a pier in a lake that was installed in the mid '70's. Never replaced a post yet, and it's close to 70' long. We used 2" galvanized pipe for posts, installing them by cutting holes in the ice, washing them in by screwing on a threaded cap, and hooking that end of the pipe to the garden hose. It washed itself down most of the way, and we pounded it the rest of the way with a sledge.
