I hope I put this message in the right place, sorry if I haven't. I would like to construct a small floating island for my duck pond. A safe haven for the ducks to nest and ducklings to rest. My pond is 100 long and 60 feet wide, and 10 feet deep. So I was thinking the island could be 10 long and 6 feet wide. Problem is, I have no idea how. I would like to have water grasses to grown on it and have it look as natural as possible. Any ideas and advice would be appreciated.
