All I do know is that it cannot be a craggy waterfall .The complete opulate drop has to be completely free falling without obstacles such as
the craggy rocks or acrevia from the rocks or hillside (from which it is falling from..This water fall cannot be so high that the perfect opulate or drop can change or be vaporized on its way down
either.It must be an waterfall with an off the main fall that drips but is considered part of the whole waterfall...But These are not bad clues..for someone who may have the best estimate for an answer.
