Bilge pump to keep water level below tiles

I have the same problem every year in that I drain the pool down to below the tiles. Winterize/cover with a mesh cover and then all the rain/snow keeps adding water until it's back in the skimmer boxes. If I was smart I would have had a gravity drain line installed below the tile line while they were building the pool. I was thinking of using some kind of bilge pump with a float switch that would turn on when the water level got too high. The big problem with this idea is I live where the water freezes so the pump idea becomes pretty complicated. Any ideas from you folks out there?

Not much you can do, especially once things freeze, up where we are, we just forget about it til spring, a couple of winters ago, I had so much snow in my AG pool that the snow was 3' above the top of the pool, just make sure that you use gizmos in your skimmer and you should be fine.
Actually, I don't quite understand why we have to drain below when the water/snow just brings it back up above again......
