Winter pool operation

[Fordracing19]

I live just north of Dfw and was wondering what should run in freezing temps. We have a waterfall , 2 sheer decent and a bubbler that all run off one side of a 3 way valve. The other side runs the returns. Also a booster pump runs off the main pump for the cleaner. Our pump and waterfall outlet are about the same elevation due to yard slope. Should the 3 way just set in the middle and let everything flow?

I'd drain the lines to the water features if any of it was easy to do so and circulate the main pool if you don't officially close it.

I guess I could remove the swg and blow out all the lines leading to the water features.

It's pretty much non-operational with water temps below 60 anyhow.
