it just doesn't look that big. I'm pretty good at judging distances in yards, but I am not good at acreage. Bear in mind, the tank is at capacity and it appears it was at capacity when those images on pg. 3 were taken. Those trees are usually on dry land and the water rarely gets that close to the road. 2.5 acres seems a bit much, but I can't argue the scale on those images if correct.
