this is one of the ideas but with smaller smoother rocks in pond with flagstone to build waterfall.
How do you put in a pond using river rock?

Our community garden has a small preformed pond about 8 by 10 feet and about 30 inches deep. We have a small spillway that sits above and a pump. We want to make it more natural with river rock lining and a waterfall instead of just the spillway. We of course have limited funds but still want a retreat for our volunteers and visitors. We would love some help and always go to your site for ideas and use many of them in our garden.
I found the video I sent my help...

Confirming that you want to tear apart this water feature and re-use the pump and recirculating system?
Yes, the liner material is critical in terms of sealing the joints.
Youll have to determine how strong the pump is for very long run and more water. Obviously the hose length needs to be increased.
The design itself, is a matter of space-confines and electrical supply.
