Water Level Decreased Over Winter

[paulyatt]

Happy spring! I had some rust that I painted over in the fall. Over the winter, I slowly lost about two feet of water. I took the cover off and don't see any tears or large holes. I don't open the pool for a few more weeks. Should I do anything now, or just wait until I open the fool and fill/treat it, then use a leak detection kit? Thanks!

Your second picture shows rusty water leaking through the painted area. That may be where the water went.

It looks like holes in the wall. The rust you can't see on the inside of the wall is always worse than the rust you see on the outside.
If those are holes, there's a risk of wall failure.
