A backyard waterfall can be as natural as a tumble of boulders feeding a pond or as clean as a single sheet of water spilling off a stone wall. The first choice is pondless or pond, because that decides how much room it takes and how much upkeep it needs. After that, it’s about the stone and the setting.
Waterfalls bring life to any suburban backyard in Bethpage. The cascading water adds movement and an ever-changing sound, whether it’s built from sleek, modern materials or from boulders for a more natural look.
Pondless or pond: which waterfall fits your backyard?
A traditional waterfall empties into a pond. A pondless waterfall drops into a hidden basin filled with gravel and decorative stone, and a pump in that basin sends the water back to the top. You get the sound and the movement without open water at the bottom.
Pondless waterfalls are a good option for Bethpage homeowners with limited space or small kids. With no standing water, there’s less algae to deal with and no open water at the bottom. They’re also easier to shut down for a Long Island winter.
A pond gives you a place for fish and water plants. Consider a natural waterfall that empties into a quiet koi pond. The sound helps mask street noise, which suits a quiet spot for reading. Asian-inspired designs typically show plenty of wood and plants, so a wooden pergola or small deck over the pond, surrounded by lush planting, fits the theme. Koi anchor the look and fill the yard with life, though a pond with fish does need more care through the year.
How is a natural rock or boulder waterfall built?
A rock waterfall starts with the boulders. Placed well, a few large stones give the water a believable path and make the whole feature look like it’s always been there. Smaller boulders combine with the falls to create authentic-looking streams and pools, and the spill stones, the flat rocks the water runs over, decide whether you hear a trickle or a steady rush.
Boulders do plenty of work away from the water too. A rock arrangement can be a focal point for the yard or an attractive part of a zen garden. Single boulders at the corners of a property can mark boundaries or fill gaps in planting beds. If you’re grouping rocks into a rock garden, space them out so plants can grow in between. Whether your taste runs to the traditional rules of a Japanese garden or to relaxed, natural outcroppings, rock arrangements handle it.
What does a modern backyard waterfall look like?
Modern waterfalls trade boulders for clean edges. An understated waterfall set into the face of a retaining wall, grill island or outdoor bar is an excellent addition to a contemporary patio. A single sheer descent of water coming out of a modern wall has a sleek look, and its minimal lines suit modern outdoor designs.
Why is stacked stone such a flexible choice?
Stacked stone water features adapt to almost any style. They carry the rugged textures and imperfections of a rustic design but are refined enough for a modern setting. The whole feature can be built from natural stone or veneered concrete. For contemporary yards, the stone can be cut precisely and chosen in dark shades, and lighting set in geometric patterns gives a sleek stone waterfall a finished look.
Custom stone waterfall or a waterfall kit?
Search for backyard waterfalls and you’ll see plenty of kits. They can be fine for a small accent, but they’re a different product from a built waterfall:
- Scale. Kits come in fixed sizes. A custom waterfall is designed for your yard, its grade and the view from the house.
- Stone. Many kits use formed or faux rock. A custom build uses real boulders or natural stone that weathers like the rest of the hardscape.
- Pump sizing. The pump has to match the width of the spillway and the height the water is lifted. Undersized pumps give you a thin dribble instead of a sheet of water.
- Winterizing. On Long Island, freeze-thaw is hard on anything with water in it. A built waterfall is planned with a way to drain down and pull the pump for winter, or with the right equipment to keep a fish pond open.
How should you light a waterfall?
Lighting makes a waterfall look far more dramatic after dark. An underwater light hidden in the pond or basin puts a soft glow at the base of the falls. Lights tucked behind the falling water make it shimmer.
Can a waterfall be part of a bigger water theme?
If a single water feature isn’t enough, you can build a theme for the whole backyard. A stream that meanders across the yard can link a waterfall to a pond, or stand on its own as the main feature. A fountain on the patio or in the yard adds its own sound and tends to draw birds.
A bird bath carved out of a boulder ties smaller features back to the stonework. If you or your neighbors have a cat, keep the bath raised. Plan its placement with the rest of the design.
What about a waterfall for the pool?
A waterfall can also be tied into your pool’s circulation system for a steady stream and pleasant white noise. Built from large, rough natural stone, it can make a pool feel more like a natural pond. That’s its own design problem, so if a pool is what you have in mind, read our ideas for swimming pool waterfalls.
FAQ
How can I create a waterfall in my backyard?
Start with the site: pick a spot you can see from the house, then decide on pondless or pond. The build involves digging the basin or pond, setting a liner, placing boulders and spill stones, and running plumbing to a pump sized for the flow you want. The pump needs a GFCI-protected outdoor outlet nearby, so plan the electrical early.
How much does it cost to build a waterfall in your backyard?
It depends on a few things. Size and height drive most of it, followed by the stone: large natural boulders cost more to buy and set than smaller stone. Excavation and pump size add to it, as does the electrical work. A pond with fish also costs more to build than a pondless basin. A design visit is the way to get a real number.
Is a pondless waterfall easier to maintain?
Usually, yes. With the water stored in a gravel-filled basin instead of an open pond, there’s less algae to fight and no fish to care for. You’ll still need to top off water lost to evaporation in summer and clear leaves in the fall. On Long Island, most owners shut it down and pull the pump for winter.
