Before you Start

Adding a waterfall to an existing pond or building a water feature with a waterfall can be easy. With a few calculations, a fair-weather weekend, and the right equipment you can have the waterfall of your dreams. There are a few things you should keep in mind...

Types of waterfall projects

  • A waterfall can be easily added to an existing pond. If you don’t yet have a pond, check out our Pond Basics Guide. 

  • A disappearing water feature is a great alternative to having a pond. They are also referred to as, "pondless" because they don't have open water at the bottom of the waterfall. Alternatively, they use a water reservoir hidden under rocks. The water flows through a rock base over the reservoir and disappears, and this cycle continues endlessly. 

  • If you don’t want to dig or you don’t have the space for an in-ground pond or reservoir, you can create a retaining wall. This is an above ground feature that uses paver stones to build a liner to build an aboveground structure. Check out our Projects for ideas. 


The waterfall needs to be positioned above the water’s surface, so you can see the waterfall flow into the water. Choose a location that you can enjoy from multiple vantage points in your yard.

Pump Size

Do you have the right-sized pump? The higher the pumping height (the distance from the pump to the spillway), the more powerful the pump needs to be. 

Water Flow

How much flow do you want? The strength of your waterfall’s flow depends on the height of the waterfall, width of the spillway, tubing size, and the pump’s size. You can have a gentle trickle, a pristine sheet, or a roaring stream of water. 

Not enough space or not able to dig in your yard?
