Winterizing a Whiskey Barrel Pond with Koi

New Jersey whiskey barrel pond (~20 gal) with 2 baby koi, water lily, iris. Asks if bring in for winter.

Barrel Pond Will Freeze Solid

Above-ground, small volume = total freeze. Fish and lily will die. Some iris survive freezing.

Action Plan

• Move koi indoors: aquarium or Rubbermaid stock tank (larger better).
• Keep lily/iris indoors (active or dormant). See overwintering plants.
• Basement or garage works if above freezing.
• Below 50°F: no feeding needed.

Note: Koi need 1,000+ gal long-term. Plan larger pond or rehome.
