Hi Jim
It's quite possible that water was pushed out of the pool over the winter by the water on the cover AND a plug of ice in the pool.
What you can do to see if you have a leak is mark the water line (I usually use electrical tape on the skimmer mouth) and see if the water drops after a day or so. {you don't have to get wet and cold this way}
There are other ways to determine what might be leaking if you are loosing water (bucket test, vessel test ...).
If you need more assistance from me on this, simply ask![]()
