My pond is losing water

How to arrange my rocks in my pond so they do not splash out and lose water?

The water looks like they are causing me to lose water off the rocks.  How can arrange them so it does not happen?

  The water area needs to be twice as wide as the height of the waterfall. If it is not, the water will splash out. That's one of those laws of physics that none of us can break. Even if the water flow is in little drops, it will still splash out. So lower your water height or make the pond bigger.
