Organizers say the ice fishing will go on at this weekend’s derby but Sebago Lake is not an option. The Cumberland County Ice Fishing Derby will happen as planned on Saturday and Sunday at other lakes and ponds in the region. Organizers say the recent storm has left conditions too variable on Sebago Lake, making the ice unsafe. They say the big lake has almost no ice and there are numerous pressure ridges along Jordan Bay with open water on either side. All prize pools from the Sebago Lake Derby have been shifted to the Cumberland County Derby.
