Dwight I put some "structure" similar to what you have in the picture in my pond with the idea that it would always remain hidden by the water. Well we have had the worst drought in fifty years going on for the last two years. This low water has caused my pond to look like a junkyard and so now I've decided to pull it out and haul it off. I think that from now on the only structure I'm going to place in the pond will be more natural looking. I am only saying this because removing this mess is more difficult than not putting it in the first place. However you may not have the water fluctuations we have in Texas and putting it in would not be objectionable. Just something to think about.
