5 Things to Know Before Building a Backyard Pond
Backyard ponds are more than just a water feature, they’re a lifestyle upgrade. Adding a pond to your yard creates a peaceful space, attracts wildlife, and turns your outdoor area into a retreat. But before you start digging or calling a pond contractor, there are some important things to know. A pond isn’t like dropping in a swimming pool or planting a flower bed. It’s an ecosystem, and how you plan and build it will affect how much you enjoy it for years to come.
Here are five things every homeowner should know before building a backyard pond.
1. Design Matters More Than You Think
When people think “backyard pond,” they often picture a hole filled with water and maybe a few koi fish swimming around. But design is where most of the success (or frustration) happens.
Start With Purpose
Ask yourself: Why do I want a pond?
Do you want a koi pond for fish-keeping?
Are you looking for a pondless waterfall where the sound of running water is the main attraction?
Would you enjoy a natural ecosystem pond with plants and wildlife?
The purpose will decide how deep the pond needs to be, what filtration you’ll need, and even where it should be placed in your yard.
Placement Is Key
A pond should feel like it belongs in the landscape. That means looking at:
Sunlight: Too much sun can cause algae blooms. Partial shade is ideal.
Slope: Low areas may collect runoff filled with fertilizers and chemicals. That can harm fish and plants.
Visibility: You want to see and hear your pond from the spots where you spend the most time — like a patio, kitchen window, or fire pit.
Size and Depth
Most homeowners regret building a pond that’s too small. A tiny pond can heat up, collect debris faster, and limit your options for fish. A good rule of thumb: if you’re keeping koi, go at least 2–3 feet deep. If you’re building a smaller decorative pond, 18–24 inches is fine.
Designing a pond isn’t about dropping water in a hole. It’s about blending it with your lifestyle and yard. Get this part right, and everything else becomes easier.
2. Maintenance Is Ongoing (But Doesn’t Have to Be Hard)
A pond is a living ecosystem. That means it changes with the seasons and needs a little care. The good news is that modern equipment makes maintenance much easier than it used to be.
Everyday Maintenance
Skimming debris: Leaves, twigs, and pollen will land in your pond. A skimmer system can collect most of it before it sinks.
Feeding fish: Not all ponds need fish, but if you add koi or goldfish, feeding becomes part of the routine.
Checking equipment: Pumps and filters keep the water moving and clear. A quick glance each day can prevent big problems later.
Seasonal Maintenance
Spring cleanouts: After winter, most ponds need a good clean to remove sludge and get equipment running.
Summer algae control: Warm weather can mean green water if your pond doesn’t have enough plants or proper filtration.
Fall netting: Nets keep leaves out of the pond and save hours of cleanup.
Winter prep: Depending on where you live, ponds may need a heater (de-icer) or aerator to keep oxygen levels safe for fish.
Hiring Professionals
If the idea of cleaning filters and vacuuming muck doesn’t appeal to you, many pond companies offer maintenance plans. Some homeowners handle the day-to-day and hire a pro for spring and fall service. That balance can keep your pond healthy without making it feel like a burden.
3. Costs Aren’t Just Upfront
One of the most common questions about backyard ponds is: How much does it cost? The answer depends on size, style, and the level of professional installation.
Upfront Costs
DIY ponds: You can find pond kits starting around $1,000–$2,000, but these often lack the durability or filtration needed for long-term success.
Professional ponds: A contractor-built pond typically starts around $8,000–$10,000 and goes up depending on size and features. Large koi ponds or recreation swim ponds can reach $50,000 or more.
Long-Term Costs
Electricity: Pumps, lights, and heaters add a little to your monthly bill. Most energy-efficient pumps cost $20–40 per month to run.
Maintenance supplies: Beneficial bacteria, fish food, water treatments, and replacement filter pads.
Professional services: Spring cleanouts or emergency repairs can add to the budget.
Value vs. Expense
It’s easy to look at a pond as just another cost. But a well-built pond adds property value and improves your lifestyle. Many homeowners say the return isn’t just financial — it’s in the hours of stress relief, family time, and pure enjoyment.
4. Not All Equipment Manufacturers Are Equal
When you start shopping for pond supplies, you’ll notice there are dozens of pump, filter, and liner brands. They are notall the same.
Major Pond Equipment Brands
Aquascape: Known for ecosystem ponds, pondless waterfalls, and easy-to-use kits. Popular for homeowners who want low maintenance.
Atlantic-Oase: Offers high-performance equipment, strong pumps, and advanced filtration. A favorite among contractors and larger installations.
Savio and Helix: Known for unique skimmers and filtration systems, often used by koi enthusiasts.
Generic box-store brands: Cheaper upfront but often lack the efficiency or durability of professional-grade equipment.
Why It Matters
The pump is the heart of the pond. A cheap pump that burns out in a year can leave you with green water, dead fish, and frustration. The liner is another big one. This is literally what holds your water in place. A high-quality liner can last decades, while a thin one may leak within a few years.
Investing in the right equipment at the start saves you time, money, and headaches later.
5. Think About the Future Now
Building a backyard pond isn’t just about the first year, it’s about how it grows with you.
Room to Expand
Maybe you start with a small pond and later want a waterfall or stream. Or perhaps you decide to add more koi. Planning space for expansion now makes those upgrades easier later.
Lifestyle Fit
Some homeowners love hands-on projects like adding plants, testing water, or watching koi grow. Others just want a pretty waterfall with minimal work. Knowing which type you are will shape the size and style of your pond.
Choosing the Right Builder
If you’re hiring a contractor, ask:
How many ponds have they built?
Do they offer maintenance plans?
Can you see examples of their past work?
The right builder doesn’t just install ponds — they help you understand what living with one is really like.
Frequently Asked Questions
What is the best size for a backyard pond?
For fish, at least 2–3 feet deep and several hundred gallons. For decorative ponds without fish, smaller sizes can work — but most people are happier with something larger than they originally planned.
How much maintenance does a backyard pond need?
With the right equipment, a pond needs just a few minutes of attention each day. Most of the work is seasonal — cleaning in spring, netting in fall, and checking pumps regularly.

Yes. Our team provides pond design, installation, and maintenance throughout Northern Indiana, including Elkhart, South Bend, Fort Wayne, Middlebury, and surrounding areas.
How much does a backyard pond cost to run each month?

Is a backyard pond worth it?
For many homeowners, yes. A pond provides relaxation, a gathering spot for family, and a way to bring nature closer. The enjoyment far outweighs the maintenance when it’s built right.
Final Thoughts
A backyard pond is one of those projects that changes how you use your outdoor space. It’s not just about water and fish — it’s about creating a place to relax, recharge, and connect with nature.
If you take time to plan the design, understand the maintenance, budget for ongoing costs, choose quality equipment, and think about your long-term goals, your pond will be a joy for decades.
