Low water in pool during the winter - advice please!

[Bill]

Last summer I knew I had a leak in my in ground pool some place but had not found it when I closed the pool in the fall. Now it is Feb and in the single digits. My pool cover collased into the pool last night due to heavy snow and lack of water in the pool. The pool is almost empty!

Do I need to pump some water in it to keep things in place or just wait till spring. I'm expecting the liner is going to be shot but is there other damage I can expect?

Any advise or recommendations are welcome.
