I have egg sized cobblestones around my pond. When my pond was built a shelf 6" deep was cut in around the top to help hold the stones in place. 6' wide landscaping fabric was laid under the stones. It works great at keeping my dogs from tearing up the edge and it keeps them cleaner when they come out, no more muddy legs and less clay gets suspended to cloud the water. I've had the cobblestones about 3.5 years now and I'm just now seeing some grass encroach over the outside edge of the stones.

The downside is the expense and it's more difficult getting plants established in your pond, not much has grown in the stones. I'm adding another 3' wide strip around the pond on the land side to make it more safe to mow around with my zero turn mower. I love the look of natural ponds just as much as the type of pond I have and for me it's easier to maintain especially with my dogs.
