Can Pond Fish Survive in a Frozen Pond?

December 2018 weather in Long Island, NY, has hovered around 50 degrees.

However, recent news that the Polar Vortex may very soon cause the northeast some winter trauma suggests we should all give a thought to our backyard ponds and especially our pond fish. 

The big question is:

Can Koi Survive in Frozen Ponds?

Pond Gases Must Escape

Pond Gases Must Escape

Some pond owners remove their koi for safe keeping in a warmer place. That is not necessary, say experts. However, it’s important to remain alert, especially if the weather gets particularly bad.

Your koi will happily lie dormant during winter months and can survive in a frozen pond as long as they can get enough oxygen. This requires;

  •  two feet of water to swim in,
  •  oxygenating the water by running waterfalls into the pond etc.,
  •  and keeping a hole in the ice with a heater, bubbler and an aerator, thereby allowing the naturally produced gasses to escape from under the ice.

If the above efforts fail to keep it from freezing, Aquascape Inc. designs manager, Gary Gronwick, suggests using a pond de-icer. 

“This will keep a little hole in the ice so gases can escape,” he says. “While some recommend boiling water to create an opening in frozen-over ponds, that should be discouraged. It will only ice up again quickly.“

Gronwick also says to avoid chopping or sawing the ice to open a hole. The noise and vibrations will stress out the hibernating fish to a point they could die.

That done, Mother Nature will do the rest. The fish will spend the entire winter hibernating at the bottom of the pond, or in a cave designed for this, and then will slowly wake up as the water warms in the spring.  The fish do not need to eat during this time and, in fact, shouldn’t be fed at all.

If you haven’t done this already, before any brutal weather sets in, carefully look over your plant material and remove dying plant material. Otherwise, these will rot and build up poisonous gases that can’t escape through ice when it forms. Such conditions might mean that the koi are no longer simply hibernating, but are in a dangerous state of torpor.

Running waterfalls during cold months helps move the water so ice doesn’t form. But if ice builds up, pond aerators can put bubbles back in the water to add oxygen for the fish.

Happy Holidays

So! If the Polar Vortex throws us all it’s got, you don’t need to worry too much about your fish. Ensure they have enough oxygen, etc., and they should be just fine. 

Merry Christmas, everyone!

“Pondless” Waterfall Features Are Easy to Create and Maintain

In order to enjoy the beauty and serenity of a flowing stream or waterfall, some sort of basin is required to capture the water. Frequently, such a basin is a pond, possibly adorned with exotic water plants as well as being a home to pond fish. But there are many who want a water feature — just not with a pond.

Those with very young children, for example, sometimes worry that a full, deep pond in their backyard might present safety concerns, and prefer a pondless waterfall (left) where river rock allows water to seep down into the ground. In addition, come spring and fall, ponds require maintenance to keep it healthy and beautiful.

Another reason for not wanting a pond came up with one our water feature clients. Their property abutted parklands, and they feared a pond would attract too many wild animals. With other clients, budget and property size are factors.

For all or any of these reasons, if you are considering a water feature, you may want to go “pondless.”

Certified Aquascape Contractor

Deck and Patio is a Certified Aquascape Contractor, which means we’ve been pre-qualified as experts in designing and building water features of all types, including “pondless” waterfalls. Aquascape offers years of experience in this field and their products are both technologically and biologically efficient. Their pondless systems allow water to drain through gravel into a reservoir, which stores the filtered water underground and recirculates it.

 

“Of course, having a pondless waterfall does not mean that it can’t be adorned with robust plantings, especially when you consider that you’ve not had the added expense of any extra labor and materials required in creating a pond,” says Dave Stockwell, owner of Deck and Patio.

For the handsomely landscaped pondless waterfall pictured here (right), we planted durable thick and compact evergreens, including the low-maintenance Procumbent Juniper, which spreads well. For splashes of color we added Begonias, Coleus, plus Astilbe with its beautiful and showy flowers.

With a pondless waterfall, you are recirculating water, which is definitely eco-friendly. But natural evaporation will require that this recirculating water be “topped off” and refreshed occasionally. For those who would prefer to go totally “green” and not use town water to replenish your stream/waterfall, Aquascape also makes a RainXchange reservoir system.

With RainXchange, runoff rainwater — either from a roof or permeable pavers is collected to maintain the water feature’s system through completely green rainwater harvesting methods. This captured rainwater can also replenish the surrounding landscape, wash a car, rinse down a deck or patio, etc., and is especially helpful during droughts.

Water doesn’t soak into asphalt and concrete and picks up contaminants

“Whether you harvest rainwater or maintain your water feature with town water, an Aquascape Inc. pondless system will keep the spillover water from running into over-burdened sewer systems,” says Dave.

“That is because we use river rock underneath the waterfall. It not only allows water to seep through to the reservoir, but it helps filter it. This river rock process is essential, because water doesn’t soak into asphalt and concrete, but, instead, flows away to the local waterways, picking up contaminants as it goes.

“So if you’re not sure you want a pond, but definitely want the sounds and sights of running water, pondless just may be the way to go,” says Dave.

You can see the river rock we used here instead of concrete or asphalt so that the water seeps through into the reservoir below.

Preparing Ponds for Winter

 

We are not alarmists at The Deck and Patio Company, but our job requires that we pay attention to credible weather forecasts. And according to Accuweather, the Northeast may be in for an extended snowy winter, stretching into spring of 2017. If you have a backyard pond, there are a few things you can do to get ready for this onslaught.

Pond Fish in Winter

First, let’s deal with the misconception that you can’t leave your fish in the pond during winter months. Actually fish do just fine in winter. They go dormant and hibernate. However, our pond expert, Bill Renter, does add that it’s well to be especially alert to their needs once water starts to freeze. Should ice, for example, completely cover your pond, the fish could become starved for oxygen.

“This can be remedied by ensuring the pond has at least two feet of water for them to swim in,” says Bill. “It’s also key for the water to remain oxygenated by keeping a little hole in the ice with a heater, bubbler, and an aerator. We use products from Aquascapes Inc. — pond experts from St. Charles, Illinois.”

Aquascapes’ designs manager, Gary Gronwick agrees it’s important to use a pond de-icer. “This will keep a little hole in the ice so gases can escape,” he says. “While some recommend boiling water to create an opening in frozen-over ponds, that should be discouraged. It will only ice up again quickly.“

Gronwick also says to avoid chopping or sawing the ice to open a hole. The noise and vibrations will stress out the hibernating fish to a point they could die.

These things done, Mother Nature will do the rest. The fish will spend the entire winter hibernating at the bottom of the pond, or in a cave designed for this, and then will slowly wake up as the water warms in the spring. The fish do not need to eat during this time and, in fact, shouldn’t be fed at all.

We’ve included in our photo captions below more tips on preparing your pond and fish for winter and how to watch over it all. Happy ponding.

Water Plants in Winter:

Water Plants in Winter:

Hardy water lilies (shown here) that float on the water’s surface and have a short blooming period can withstand the cold winter months nicely. Lotuses also can withstand the cold winter months because they bloom in summer and go dormant in winter. Note that frost kills water hyacinths; water lettuce, which fights algae, should be wintered in a warm spot that is well lighted as they will not survive in the pond over winter.

To be on the safe side, take water temperature regularly once it hits 55 or lower. If your pond jewels are hungry and moving about and you haven’t fed them, they will find something in the pond to eat and soon will be dormant anyway.

 

 Pond Caves for Fish:

Pond Caves for Fish:

Ask your pond designer/builder to create a small cave, or caves, where the fish can hide from predators in warm weather, and where they can also lie dormant during the winter months. Caves are easily made from the way rocks are positioned in and around the pond.

 

 

Natural Swimming Ponds: Embracing the Pond Life

Updated 6-29-23

Aquascape’s Ed Beaulieu, known to many as The Pond Professor, highlights in a recent video that a growing trend in the landscaping world of outdoor living spaces is what he calls “a living pool or recreational pond.” 

“A recreational pond is water the way nature intended it — full of life, with fish, a home for pollinators, water lilies, all living together, symbiotically, creating a beautiful serene setting,” says Ed.

How’s that for a description of idyllic outdoor living!

Our own Dave Stockwell adds: “Indeed, these natural swimming ponds are so popular today that Aquascape has come up with a do-it-yourself kit for creating one in your own yard (see video). Deck and Patio can certainly help you obtain what you need to do that and walk you through any questions. Or if you prefer, we can design/build one for you.” 

This pond, for example, is one of two ponds a client asked us to create in their yard — a yard which overlooks beautiful Long Island Sound:

More examples of Deck and Patio natural swimming ponds, including this one, and information about the natural pond experience  continues below. 

According to reports, across ‘the pond’ in Europe, natural swimming ponds have grown in appeal for a quarter of a century. Here at home, however, North Americans have not yet joined the craze with equal zeal. While swimming au naturel (chemical free) certainly appeals to health-conscious North Americans, some can’t get over sharing their backyard swimming water with — ewww — bugs, tadpoles, let alone pond fish.

This, however, may be changing. After all, a man-made natural pond is no different from swimming in a lake, swimming hole, or swimming in the ocean. Who hasn’t brushed up against seaweed, or snorkeled to enjoy colorful fish? And, indeed, in recent years, Deck and Patio has been asked to create man-made ponds on Long Island for the pure enjoyment of swimming in them.

In a recent post on Aquascape Inc.’s website entitled: Growing Up Around a Pond, the writer focuses on the ’10 most interesting things’ she has learned from having just such a pond:

          all bacteria is not bad;

          swimming in a pond is more fun than in a pool;

          ponds are wondrous at night;

          ponds are better than TV or video games.

We would have to agree with her. Snorkeling in a regular swimming pool isn’t all that exciting.

Don’t let the bugs bug you:

Unchecked by the chemicals of a regular swimming pool, the odd dragonfly will no doubt flit across your natural pond’s surface. You may spy a salamander at its edge. And frogs (who eat the more undesirable insects around your pond) may parent some tadpoles in any natural pond. And if there’s koi in your pond, you’ll want to keep them healthy and free of disease.

That aside, swimming in a pristine natural pond is very possible and thrilling. Using the right underlayment, liner, Biofalls and skimmers, bog filtration and water plants are part of creating the perfect experience. Detailed information on how to do this can be found on such helpful websites as Aquascape Inc’s, and local pond experts can aid you in keeping your water clean, and your fish healthy.

Now you may think that our beautiful model is avoiding the ‘ewwww’ factor by using a floating device. But as you’ll see from the next photo below, she’s not bothered at all by healthy pond life. Indeed, this pond is pure and clean — a joy to swim in.

A key factor in a good natural swimming pond is to build it big and deep enough so that you can snorkel as well as have room to swim.

Some ponds, like this one, is intended as a koi pond and not a natural swimming pond. One way to ensure you pond is sufficiently pristine for swimming is not to overload it with koi or other pond fish. This allows the aquatic plants and filtration systems the ability to absorb and “clean” the pond sufficiently for an enjoyable swim.

Keeping Pond Fish Safe and Healthy in Winter

Updated 11-30-23

Fall Backyard Maintenance: Along with covering your swimming pool at the end of summer, it is helpful in due course to put up pond netting to collect foliage debris; nets also offer an extra layer of safety for your pond fish by protecting them from birds and other animals.

Fall Backyard Maintenance:

If you’ve seen to fall maintenance for your pond already, you’re on your way to ensuring a safe and healthy pond in winter. By fall maintenance, we’re referring to cleaning the skimmer basket, trimming any dead or dying foliage, preparing your waterlilies for winter, etc. 

And you also need to add cold water bacteria to help keep the water clean and clear.

 

Getting Ready for Winter

It is a common myth that you can’t leave your pond fish outside once the cold sets in. Actually, fish do just fine during winter. That said, Deck and Patio’s own Dave Stockwell does caution to be alert. When ice covers the pond, the fish might not be getting enough oxygen.

This can be remedied as long as you give them:

  • two feet of water to swim in,
  • oxygenate the water,
  • and keep a hole in the ice with a heater, bubbler and an aerator. This allows the naturally produced gasses to escape from under the ice.

If the above efforts fail to keep it from freezing, Aquascapes Inc. designs manager suggests using a pond de-icer. “This will keep a little hole in the ice so gases can escape,” he says. “While some recommend boiling water to create an opening in frozen-over ponds, that should be discouraged. It will only ice up again quickly.“

Gronwick also says to avoid chopping or sawing the ice to open a hole. The noise and vibrations will stress out the hibernating fish to a point they could die.

That done, Mother Nature will do the rest. The fish will spend the entire winter hibernating at the bottom of the pond, or in a cave designed for this, and then will slowly wake up as the water warms in the spring.  The fish do not need to eat during this time and, in fact, shouldn’t be fed at all.
