There is (was?) a project to do your first structure in the Atacama Desert in Chile:

> Espejo de Tarapacá (EdT) – one of the most innovative infrastructure projects in the world – is comprised of a 300 MW pumped hydro storage plant that operates with seawater, located approximately 100 kilometers south of Iquique. This project is essentially a large electricity storage system which will eliminate, at a low cost, the intermittency of non-conventional renewable energy – such as solar energy.

There’s one in the mountains of Virginia too: https://en.wikipedia.org/wiki/Bath_County_Pumped_Storage_Sta...

I wonder if salinity and salt accumulation could become a problem in the upper body of water due to evaporation.

But I guess you could get around it by monitoring and clever mixing.

Don't forget you get 2.7% more mass per volume from the salt!
