To prevent a natural swimming pond from freezing in the winter, you can take a few steps to keep the water from getting too cold. One option is to install a pond heater or aerator, which helps maintain water movement and keeps a portion of the surface from freezing over. Aerators also help with oxygen exchange, which is important for fish and beneficial bacteria during the colder months.
If you live in an area with extreme winters, consider creating a deeper pond, as deeper water is less likely to freeze completely. In some cases, people allow their ponds to freeze but leave a small, unfrozen area for wildlife or to prevent the entire pond from freezing solid. Using a cover or protective netting over the pond can help prevent ice from forming too quickly and reduce debris buildup.
