I would say there 7 or 8 years old. When i look at my property, the big metal bldg is not up yet and the pond is the smallest it ever was. The guy who owned the place before me made the pond bigger, and that was seven or 8 years ago but he only had the place here 9 years so the photos are about 7 or8 yrs old. Then, I got it I made it even bigger. I cant wait to see a new areial shot.
