Introduction to Large Ponds

The Large Pond Series

In this series of articles, we’ll look at several valuable topics for the large pond owner, especially those who are still potential pond owners. As we go, we’ll consider the benefits and challenges of large pond ownership, so if you’re still sitting on the fence, this may help you define your position better. And don’t forget! Even if your logical mind says no, sometimes it’s ok to let the passion of your heart rule.

Is My Pond Large?

Surprisingly, no official criteria exist that distinguish a pond from a lake. While most sources agree that ponds are generally smaller and shallower than the average lake, that leaves much wiggle room.

According to one source, a pond is a body of water less than 0.5 acres (150 square meters) in area or less than 20 feet (6 meters) in depth. A lake is defined as a body of water bigger than 1 acre (4,000 m²), which begs the question of what we should call those poor overgrown puddles of 0.8 acres?

According to the Illinois Department of Natural Resources, on the other hand, bodies of more than 20 acres of water are considered lakes and reservoirs, while those under 20 acres are ponds.

Ponds are shallow enough to allow sunlight to reach the bottom, which causes plants to grow at the bottom and on the surface. Lakes usually are much deeper than ponds and have a larger surface area.

In fact, many natural lakes are over 1000 feet deep, including the five deepest lakes in the US: Crater Lake, Oregon; Lake Tahoe, California/Nevada; Lake Chelan, Washington; Lake Superior, Michigan/Wisconsin/Minnesota; and Land Pend Oreille, Idaho, but the Great Salt Lake in Utah goes no deeper than 33 feet.

On the other hand, New Hampshire doesn’t work on a simple measurement. According to them, if a waterbody during the summer is deep enough to stratify into three distinct layers, with one warm layer on top, one cold layer at the bottom, and a layer of rapidly changing temperature in between (called a “thermocline”), then it is a “lake.” At the same time, a waterbody with one or two weakly defined layers is a “pond.”

Ultimately, deciding whether your watery oasis is a big pond, or a small lake is yours. Most bodies of water were named arbitrarily during settlers' days, explaining the famous “Walden Pond,” an undoubtedly lovely puddle with a spread of 61 acres and a maximum depth of 100 feet.

In this series of articles, we’ll consider anything between 1 and 20 acres with a maximum depth between 8 and 20 feet, a large pond. Don’t worry; no matter the size of your “large pond,” you’ll find helpful information here!

The Rewards

One of the most significant benefits of having a large pond is the visual impact it creates. The tranquil sight of clear, shimmering water nestled amidst lush greenery can instantly elevate the beauty of any outdoor space. Large ponds provide a sense of serenity and create a calming atmosphere, making them a perfect addition to gardens, parks, or commercial properties. The reflection of the surrounding landscape on the water's surface adds a touch of magic, making your outdoor oasis a feast for the eyes.

Moreover, large ponds provide a haven for wildlife. They attract many types and varieties of wild creatures, including native birds, amphibians, and insects, fostering a healthy, diverse ecosystem in your backyard. This biodiversity can bring about an exhilarating sense of being connected to nature, which is especially difficult to achieve in an increasingly urbanized world.

In addition to their aesthetic value, large ponds can significantly enhance the value of a property. Real estate agents often highlight such features as key selling points. Prospective buyers are typically drawn to houses with unique elements, and a well-maintained pond can provide a distinct edge in the market.

The Challenges of Ownership

Despite these benefits, owning a large pond comes with its share of obligations. One of the primary concerns is maintenance. Regular cleaning and filtration are crucial to prevent algae and debris buildup. Maintaining the appropriate water chemistry and temperature for fish health can also be time-consuming. Additionally, larger ponds may require frequent inspections and repairs due to their size. It's essential to be prepared for the ongoing maintenance tasks of owning a large pond.

Another drawback of having a large pond is the associated cost. Building and maintaining a large pond can be a significant investment. Construction costs can vary depending on the size and complexity of the pond, including excavation, liner installation, and landscaping. Ongoing expenses, such as electricity for water pumps or filters, fish food, and water treatments, should also be considered. Additionally, if you plan to hire professionals for maintenance tasks, such as pond cleaning or fish care, these services can add to the overall cost. It's essential to weigh the financial implications before committing to a large pond project.

Safety concerns can arise regarding large ponds, especially if you have young children or pets. The depth and size of the pond can pose a drowning risk, requiring additional precautions. Safety features like fences, nets, or alarms can help mitigate these risks. It's crucial to be aware of local regulations and safety guidelines to ensure the well-being of everyone who interacts with the pond. Regular supervision and education about water safety are essential to enjoy a large pond's benefits without compromising safety.

In conclusion, large ponds offer a range of benefits that can transform your outdoor space into a captivating oasis. From enhancing the aesthetic appeal to supporting biodiversity and promoting relaxation, these water features have much to offer. However, it's important to consider the drawbacks as well. The high maintenance requirements, cost implications, and safety concerns associated with large ponds should not be overlooked. Before deciding to create a large pond, carefully evaluate your resources, preferences, and the specific requirements of your property. By weighing the benefits and drawbacks, you can make an informed decision and create an outdoor oasis that perfectly suits your needs and lifestyle.
