January pond care in Pennsylvania

Winter is planning season. The permits you need for spring work take time, and some must be approved before you start.

• Safety

  Never assume pond ice is safe; stay off clear ice under 4 inches; aerated ponds have open water.

• Care

  If ice and snow stay on for weeks, clearing snow from part of the ice lets light reach the plants so they keep making oxygen. Penn State suggests keeping roughly 30 percent of the ice free of lasting snow, but only where the ice is safe for the way you clear it.

• Care

  Running an aerator? Penn State says it doesn't need to run all winter: turn it on when ice forms and off when the pond is ice-free. Keep people off ice near it.

• Permit timing

  Plan this year's weed and algae control now. Any herbicide or algaecide in a pond needs a joint DEP/PFBC Chapter 91 permit first, at any amount.

• Permit timing

  Thinking about grass carp? PFBC grass carp permit needed for each waterbody before buying or stocking; $85 fee, returned if denied. PFBC's current form gives no processing time, so apply early.
