pond rebuild

[odin5738]

I'm in the process of rebuilding my pond. This will be my first attempt at building a pond and waterfall. My pond is situated at the bottom of a hill which will provide a nice drop for the waterfall. I'm planning on a small retaining wall partially submerged on the edge of the pond and run continuously under the waterfall. I'm concerned with the connection of the waterfall to the pond. At the top I'll have a biofall to start and run down to a water fall that will drop 18" to 24" into the pond below. I want it to overhang the retaining wall made of 8" wide dry stack strip stone. Will I have leaking issues if I run the liner under and behind the retaining wall and up to the waterfall stating point overlaping the pond below?
Is there any threads showing pictures of a waterfall pond conection?
Thanks

Here is my rebuild thread. As long as your liner is under all your structures you should not have any leak issues. Run the liner under and behind the dry stack wall. Use PL roof sealant and pond foam to close up gaps.

If you are building at the bottom of a hill, do take note of runoff from rain that may happen into the pond. You might want to build it slightly above ground to prevent that from happening.
