Get Full Enjoyment From Your Pond, Pondless Waterfall, or Outdoor Fountain During Winter
Is your water feature at risk of freezing this winter? What steps can you take to keep your pondless waterfall or fountain safe from the cold?
In this post, we’ll show you how to protect your pondless water features, fountains, and koi ponds from freezing during the winter months.
By the end, you’ll have the knowledge to keep your water features running smoothly and avoid costly damage caused by ice.
How to Keep a Koi Pond from Freezing
Keep the Pond Aerator Running
Aerators are vital for keeping your koi pond healthy in the winter.
Aerators circulate the water, which helps maintain oxygen levels in the water, prevents the pond from freezing over, and keeps harmful gases from building up under the ice.
Keeping the aerator running will ensure your koi have the oxygen they need to survive the winter months.
Install a De-Icer for Shallow Ponds
If your pond is shallow, you may need a de-icer.
For ponds less than 3 feet deep (2 feet in Maryland and warmer areas), a de-icer is necessary to prevent the entire pond from freezing.
Place the de-icer in the center of the pond. It will keep a portion of the surface unfrozen, giving your koi a safe area to swim. Be sure to remove any non-essential equipment from the pond, as frozen water can easily damage it.
Don’t Break the Ice
If you see ice forming on your koi pond, resist the urge to break it.
Breaking the ice can harm both your fish and your pond equipment. Instead, use an auger to carefully drill holes in the ice. You can also fill a pot with hot water and sit it on top of the ice or use a de-icer. This lets gases escape and allows for better air circulation.
Once holes are made, ensure your aerator keeps the water gently moving.
Monitor Water Temperature
Koi fish are sensitive to temperature changes.
The water temperature should never drop below 39°F (4°C). Use a pond thermometer to keep track of the temperature. If the water gets too cold, consider using a pond heater to maintain a safe range.
Adjust Feeding Practices for Winter
As the temperature drops, your koi fish’s metabolism slows down.
Switch to a wheat germ-based food for the winter months. Stop feeding them altogether when the water temperature falls below 50°F (10°C). This prevents overfeeding and helps keep your koi healthy throughout the cold season.

Clean and Maintain the Pond
Before winter fully sets in, clean your koi pond.
Remove leaves, debris, and any organic matter that could decay. Decaying matter can lead to poor water quality, which can harm your fish. Keeping the pond clean is key to maintaining a healthy environment during the colder months.
Use Cold-Water Bacteria and Enzymes
During winter, use cold-water beneficial bacteria to help break down organic material in your pond. These bacteria are specially designed to work in cooler temperatures. They help keep your pond’s ecosystem healthy and balanced during the winter months.

How to Keep a Pondless Water Feature from Freezing
Understanding Freezing Risks for Pondless Water Features
Pondless water features, like fountains and waterfalls, may not seem prone to freezing, especially in milder climates.
But they can still suffer during extreme cold.
The water in the feature can freeze if left unchecked. This can lead to cracked materials, damaged pumps, or blocked plumbing.
Even if freezing isn’t common in your area, it’s best to take precautions before it gets too cold.
Preventing Freezing in Pondless Waterfalls
A common issue with pondless waterfalls is ice damming.
Ice dams happen when ice, debris, and/or rocks begin building up dams that block the waterway. Eventually, this forces water out of the sides of the stream. This will run the pump dry and cause damage.
You can pour warm water over ice dams to melt them.
To prevent ice dams, unplug the pump and disconnect the plumbing. Drain the tubing and store the pump properly.
Ice may form over the waterfall/stream, but water will still be running underneath the ice. At this point, the ice actually acts as an insulator from the cold.
If you unplug the pump, make sure to drain the tube and store the pump in water. This way, it doesn’t dry out and crack.
What Premier Ponds Says
I prefer, at a certain temperature and duration (let’s say 25 degrees for more than a couple of days), to just turn it off.
Since it doesn’t sustain life that needs oxygen, it’s easiest to unplug the pump and plug it back in when it thaws out. To do this, you only need to make sure that the plumbing will drain of water and not freeze and crack fittings.
It’s also important to ensure the basin where the pump is located is full of water so the pump doesn’t freeze.
How to Keep a Fountain from Freezing
Drain the Fountain Completely
Before winter hits, it’s crucial to drain all water from your fountain.
Freezing water can cause both the fountain and the pump to crack. Make sure to remove every drop of water.
You can use a scoop or bucket for small fountains. For larger ones, a shop vac will do the trick.
Make sure the fountain is completely dry before the cold sets in.
Disassemble and Store the Fountain Pump
After draining the water, disassemble the fountain. This makes it easier to clean and store.
Removing the pump is key. Store it indoors where it’s warm to avoid damage. Before storing, clean the pump thoroughly. Use mild dish soap and water to remove debris. This will help the pump run smoothly when you set it up again in the spring.
Cover the Fountain for Protection
Once your fountain is drained and cleaned, it’s time to move or cover it.
If your fountain is too large to move, cover it with a tarp or protective cover. This shields it from snow and moisture.
If you’re leaving the fountain outside, place absorbent materials like towels or burlap in the basin. These materials will soak up any moisture that seeps past the cover, adding an extra layer of protection.
Don’t Use Antifreeze or De-Icers
Never add antifreeze or de-icers to your outdoor fountain. Antifreeze is toxic to pets and wildlife. It can also damage the pump. The best way to protect your fountain is to drain the water, clean it, and store it properly.
Additional Tips for Winterizing Your Water Features
Inspect and Clean Equipment
Before the cold sets in, inspect all equipment related to your water feature.
This includes pumps, filters, and any other parts that stay in the water. Clean them thoroughly to remove any buildup.
Ensure everything is functioning properly before storage. This will help avoid any surprises when you reopen your water feature in the spring.

Prepare Your Water Features for the Next Season
As winter comes to an end, it’s time to prepare your water features for the warmer months.
Clean out your pond or fountain, removing any debris that may have accumulated over the winter. Check your equipment for any wear and tear.
When everything is in good shape, return all components to the system and get ready for the warmer season ahead.
FAQs About Freezing Water Features
Will koi survive a frozen pond?
Koi cannot survive in a completely frozen pond due to reduced oxygen levels and harmful gas buildup. To ensure survival, maintain an opening in the ice using a pond de-icer or aerator for proper gas exchange. A pond depth of 3 to 5 feet prevents freezing solid and provides a stable environment.
*2 foot minimum depth in Maryland.
Should I turn off the fountain in freezing weather?
Yes, you should turn off the fountain in freezing weather to prevent damage. Freezing water can crack the fountain’s structure and harm the pump and plumbing. Drain all water from the fountain before temperatures drop below freezing, and restart it once the freezing threat has passed.
