Pumped hydro can work anywhere that has hills. It's just a lot cheaper in some locations than others, due to favorable geography.
Water use just has to keep up with evaporation on average.
I'm not sure why building a reservoir needs to be an "ecological nightnmare" except in the sense that it's a sudden change to an environment.
