Backyard Waterfall and its Features

In planning to build backyard waterfall, you should mind on two things: the pond in which water will falls and the shape of waterfall above pond. It is often more difficult to build waterfall than pond. You should use the stones, which many people have on their own backyard or can be easily found. 

I have a pretty big slope in my backyard.  Can someone  advise me on the process of building up the front side of the waterfall.  I have started digging, and in order to have a level surface area, I will need to build up about that much.  The previous homeowner had a pallet of stones that were about the same amount, so I am looking for an idea where I can use the pallet of stones, without having to purchase thicker ones.  Thank you.
