Hi everyone, Attached is a crude image (sorry, I just wanted to get something visual done up..!) showing a pond and waterfall project I am starting soon. I have built several ponds, several pondless and regular waterfalls, but this one is throwing me for a little bit of a loop due to never having worked on something quite like this.. You can see from the image that the water level will be approximately 18 - 24" above lawn grade.. I have always had my liner just come up onto final grade in the past, but on this one I need to have it contain the water level just below the tops of the boulders that will be surrounding it. My question, as shown in the picture, is about that specific area... How would you finish that section off nicely and securely? A couple notes about the "flavor" of the pond, to provide some framework: -Natural as can be -River rock covering the liner as much as possible. I may slope the grade more gradually than shown to allow river rock on the sides as well -I have control over most things, but the water level and the boulders over the lawn grade is not something I can change on this project. I have thought of a few solutions, but most of them seem pretty mickey mouse.. and I know that there is likely something nice and tidy and secure that I can do there, and likely right in front of my nose, but for whatever reason it beats me!! Anyways, thank you in advance for any and all input on it! Cheers.
