Does it lose water and then come to a halt?
The leak would be there.
Or if you turn off the waterfall does the
leak stop?

I turned it off and the leak continued. I panic when it gets below a
certain level and then start adding water, so I can't be sure where it
is. A couple really big rocks have fallen in and I suspect one of them
tore the bottom.
