Back when I used to fish Junior Club matches on the canal I remember fishing a few where the ice needed breaking, including one on the canal under Spaghetti Junction, never did catch much and I think I remember the matches being called off early. But one of the adult runners used to break the ice with a breaker so I've never had need to do it myself, in fact, I've just checked and the two local fisheries I fish have said they are closed over the last few days due to the lakes being frozen, so no ice breaking.
