FWIW-here are a couple of photos of the two ends of the pond. If they appear in the order I included them the first is the smaller end and the second is the larger end.
I took both photos from about the same spot one one side near the center. The photos cannot show it but the smaller end is on an angle in relation to the larger end. In other words near about mid point there is a bend in the pond.
The pond was about 1/2 full when I took these.
Thanks
