there are 2 ways (that I can think of) to achieve a waterfall like effect (its only an effect, the upper lake wont be accessible with water units and the entire mountain wont be accessible with land units. Air units wont change their elevation due to it either, so dont make it too high):
1) create a custom prop that uses something like the tracks for tanks (basically a part of the texture is moving from left to right and thus creating some illusion of moving parts). I am not sure if thats possible for non-moving units.
2) have a look at the nomads shield, it has a yellow/orange wave going over it from time to time. Using this method would mean to create a prop and a second (waterfall shaped) structure where the entire texture is moved.
I would try the second method, but both of them require significant effort (and modeling skill)
