Waterfall help!

[Mostyn]

Can anyone help, I need a detailed plan for a natrual rock waterfall That I
would like to build on the edge of my pond.
I have no idear haow to start it, I know I need a sump for the water but its
how to lay the liner and hide it and have the water run through the last two
layers of rocks.
Any designs would be greatfully appreciated.
