And do they actually suck water from downstream to pump it back into

Yes. In California a few years ago, during one of their periods of energy
scarcity, several generating stations pumped water back into the resevoir
during off-peak hours (night). The California equivalent of a
perpetual-motion machine.
And where did they get the power to run those "pumps" ?
I would imagine it comes from some of the water flowing
through the generator, which would be the most logical source.
Ah, thermodynamics repealed!
