What are these snail-like things living in my pool cover?

I discovered a group of these baby snail creatures living underwater, on the side of my pool cover. They have shells and look like snail, but I didn't think snails could live underwater like that. What are they?|||There are freshwater snails. They live on algae. They have to come up to the surface sometimes to breathe, which they do through a breathing tube on their side.
