Ice Rink in the backyard means...

So, the ice rink in the backyard (a natural one, mind) has created some havoc in the basement.  Today rain came instead of snow.  The rain had nowhere to go due to the frozen ground.  The rain is, as I write this, pouring in through the granite of our basement.  I've removed almost all items that can be damaged by standing water but I have no way to get said water out of the basement.
