Now my idea for the waterfall part was to take a bucket and plumb the incoming water into it. I would create a weir area out of a flat piece of flag stone. I foamed this rock into position. On the inside I used a larger rock to brace the inside portion of the weir rock.

I used a 1.5 thread to slip pvc connection to a 90bend pvc joint out of the bucket. Why the bucket? Well, I don't like to just simply throw the pipe or hose of water behind rock and let er' rip. You really have to work with getting a nice even distribution of the water, and if it is really flowing, the water shoots right off the rock like a ramp, and kills the look. By having the water pool first-- you slow down the fast flow and can create a nice even spill off a weir rock.

Here is my bucket above.

Building the rock around the bucket to hide it, I foam as I go. Using gravel to fill in large holes, then coming back with foam to congest that area, and push the water OVER. Always think where the water will run and foam accordingly. Splash dirt and gravel on foam that is visible to hide it. No one likes to see nasty yellow-orange foam :P Keep buckets of small gravel, larger gravel, and sand or dirt nearby so you can quickly grab what you need and foam fast. (Front view above.)

In this shot, I've connected the incoming water flex pvc to a small section of pvc pipe and into the bucket.

All done.  Blue arrows are water flow I was hoping to achieve in building with the rocks and their placement.
