When I step into the pond, the ENTIRE WATER LEVEL RISES AT THE SAME TIME! Water must travel instantly?
So, a hydro dam is actually a method for sucking the energy out of the entire surface of a lake, all at the same time! (Actually the pressure-waves travel at the speed of sound in water, a few thousand MPH.) It doesn't happen instantly, but damn close.
