| Quote from Minh "I will have one shallow edge of the pond where it will be a slight slope of bed rock and small pebble."
I had this I think when I built my first pond. A little beach area where you could see stones going down into the water. It was very beautiful and serene. A miniturization of a scene. Because I used pea stone and because of some "hanging out" I did in Georgetown a long time ago I called it "P Street Beach."
Funny thing though. The herons looked at it as an invitation. And they walked into the pond using it as their ramp. It was eliminated after their lunch.
The big stones are fine if you understand the logistics of moving them, placing them and supporting them long term. Have you decided to use concrete to stabilize your soil around all the edges of the pond? Concrete can be formed thick enough and wide enough to make a stable ledge for these rocks all at the exact level of your water. Liner would go over the concrete and would also be raised along all of the back edge of the stones. An overflow of the correct height keeps water and food from going into the rocks, but you will still need to keep rain from washing things out of the rocks into the pond. Discreetly mortaring these rocks in place, over the liner, may be the best way to avoid this runoff and the entry of debris that has been caught in the rocks. The mortar should probably be sealed so it doesn't leach into the water when new. If there is a pronounced slope away from all edges of the pond it could be only a small problem about this runoff and you could maybe skip the mortar but still, keeping all of these crevices clean would be a vigilant precaution.
