Do you need to run the waterfall during the winter for your pond?

Running a waterfall during winter can be beneficial for your pond, as it helps to aerate the water and prevent it from freezing completely. However, if temperatures are extremely low, consider reducing the flow or shutting it off to avoid damage from ice formation. Additionally, maintaining some water movement can prevent fish from becoming stressed due to a lack of oxygen. Ultimately, it depends on your specific pond conditions and the local climate.
