I agree that the pond should come out farther. Especially if you want the waterfall in the corner. My mother had a pond that was about 4-5" from her fence, which gave her plenty of room to build a gradual slope to the waterfall, room for small shrubs/small trees, a bench, and using a waterfall with lava rock and scrubber filter pads.
Also, I would check a local pond club for min. depths for your area.
Might also rethink that whole "hope I don't hit any pipes or lines." Your little pond project might become rather expensive, if not deadly, once you start chopping away at the hard soil below the soft top soil.
