Bass are not renowned for being caught through ice. They tend to go very dormant in the cold, low-dissolved oxygen conditions of winter. This year (early 2021) was an exception, possibly thanks to the relatively open winter that preceded a few fiercely cold spells that finally caused pond ice to form.
