I didn't want to get into an argument about construction CO2 and emissions from the reservoir.

But i would certainly class Hydro as green.

Sure, I get that. Dams often involve lots of concrete, which emits insane CO2 during production; and dams devastates large areas of nature (or human settlements).

Just felt it weird to state that natural gas is required for a stable renewable power grid, when hydro exists. Wherever hydro is possible, it's almost certainly better than natural gas in most aspects.

If you have hydro you definitely use it.

But the opportunities for adding new pumped hydro are very few.
