Your primary winter maintenance goals are protecting equipment from ice damage and managing water levels to prevent overflow. Ensure you have enough empty space at the top of the bank to handle sudden heavy snowmelt and expanding ice without overflowing.
Monitor liquid levels through the season, since frozen surfaces can hide changes that point to seepage or overflow risks. When the weather briefly warms, a quick inspection during the thaw will often reveal any issues caused by shifting soils or melting snow so they can be fixed before the next cold spell.
