I would like to see the OP reply.....hate to see someone get hurt here.

While OSHA regulations wouldn't apply to you, most likely if what I am understanding of your construction is correct, you are more likely than not in violation of your local building codes and may very well have created a dangerous situation for you and your neighbor.

Looks like a pretty cool pond but not sure how to help

Someone mentioned Rock on a Roll. I used it on our pond to hide the liner around the pond and on the waterfall. It is ok to have it submerged. However, I think the color is going to be wrong for your rocks.

yes, i mentioned the rock on a roll. It looks perfect in your application because it blends in seamlessly. You are right in that it may not work in the case of this pond because it is largely very dark in color.
