You didn't say where the hole is. If it's on the bottom you can temporarily plug it pretty well by laying a piece of plastic sheeting and dropping a sandbag on it. Plastic sheeting from Home Depot and the sandbag can be an old pillow case or something like that. It will slow or stop the leak until you get the patch stuff ready. My patch was done in Spring 05 and it's still holding well with no sign of lifting. Just ask if I can be of any more help and good luck.
