Did I drain too much? Photo included

[Trick]

Crud, started draining the pool and completely forgot... 3 hrs later and she's much lower then I would like.

I probably drained about a 3rd of the water.

Do I need to fill this up more or is it going to be OK for Michigan winter and fill it up in the spring.

My fear is the sides colapse in or liner pops out of track or who knows!

Thank you for any advice.

Do you plan on covering it? If not, I would suspect leave it and let the snow & rain fill it back up. Existing water should keep the walls and liner stable, but let's see what @Newdude thinks.

+1. With no cover it'll be up 8 inches by the time it freezes. If covering I'd want more water or a very loose cover. The water needs to support the load above the cover so it would have to be that loose that the cover floated.
