If we want to create a 'live well' on the ice, we will cut a line of 6 or 8 pairs of holes 2/3rd of the way down into the ice, and just barely touching each other -- then using a spud, chip out the sides between the holes so they are all connected, and then punch through the bottom of one of the corner holes to fill it with fresh water (if the hole is too big that you risk fish escaping, jam a rock into it)! We have kept fish alive all weekend using this type of 'live well'...!
