  • Take into account the prevailing winds and avoid placing the waterfall in a spot that can cause excessive splashing.
  • Consider factors such as wind chimes or traffic in the area and determine if the sound of the waterfall will be drowned out.

Deciding On The Waterfall Size And Shape

Waterfalls come in various shapes and sizes, and you need to determine what works best for your pond and surrounding landscape. Here are some tips to help you decide on the right waterfall size and shape:

  • Consider the overall space and a proper size ratio to the pond.
  • A larger waterfall needs a more substantial water supply to prevent aeration problems.
  • Determine the height and width of the desired waterfall.
  • Decide on a waterfall that suits the overall style and theme of your backyard landscaping design.

Creating The Pond And Water Reservoir

Digging And Shaping The Pond Area

Before starting, you should always measure the pond area markings, making sure that it fits nicely in the chosen location. Ensure that the size of the pond is appropriate for the yard, pool or garden. Here are the steps to follow:

  • Start digging the chosen area, making sure that it is evenly deep. The ideal depth for a pond is around two feet.
  • While digging, shape the pond according to the design you had in mind. You can shape it any way you want, round or oval, depending on the look you want to achieve.
  • Once the hole is dug and shaped, remove any debris and rocks that could puncture the liner.

Installing The Liner And Water Pump

After the pond has been dug, shaped and debris-free, it’s time to install a liner and a water pump that will keep the water circulating. Here are the steps:

  • Install the pond liner, ensuring that it fits snugly into the pond. The liner should be long enough to reach the edges of the pond without leaving any gaps.
  • Fill the pond with water, allowing the liner to settle to the contours of the pond’s shape.
  • Place a water pump in the pond. Make sure the pump is in the best location to keep the water moving and flowing.

Creating A Reservoir For The Waterfall Water

To create a natural-looking waterfall, a separate water reservoir is necessary. The reservoir should be connected to the pond’s water pump to keep the waterfall flowing. Here are the steps to do this:

  • Dig a separate hole next to the pond deep enough to hold a large plastic container or bucket, which will be used as a reservoir.
  • Place the container in the hole, ensuring that the reservoir’s opening is slightly above the desired height of the waterfall.
  • Connect the pump to a flexible hose and place the other end into the reservoir.
  • Fill the container with water, keeping the water level low enough to ensure that the pump is always submerged.
  • Finally, turn on the pump and adjust the flow of water for the best possible waterfall effect.

Building The Waterfall Structure

Choosing the waterfall design is only the first step in creating an impressive pond waterfall. Once you’ve decided on the design, it’s time to start building the structure. Follow these steps for success:

Creating The Waterfall Structure

  • Begin by digging a hole where you want your waterfall to be. This hole should be deep enough to accommodate the first tier of your waterfall structure.
  • Install a pond liner, and make sure that it reaches the bottom of the hole and extends outwards, beyond the hole’s edges. Then, place a layer of sand over the liner to create a foundation for the structure.
  • Next, place the first tier of your waterfall structure which usually include a water pump. Make sure that it is level and secure. You can use cement or an adhesive to support the structure.
  • Connect the water pump to the water supply, ensuring that it is covered with water before turning the pump on.

Covering The Structure With Stones And Boulders

  • Once the core part is done, cover the structure with stones and boulders to blend seamlessly with the surroundings. Use both bigger and smaller stones to create dimension and texture to your waterfall. After each stone is placed, shore it up with fill materials like grout or fine sands.
  • If you want to make the structure look more natural, plant small trees or shrubs around the waterfall. Using natural and indigenous materials is encouraged.
  • Add some decorative touches to customize your waterfall, such as adding colored lights or adding a layer of paint or sealant for extra colors.

By following these simple steps, you can build a beautiful and impressive pond waterfall to complement your backyard oasis. Remember, the key to a good installation is both consistency and creativity, and over time, it will become the centerpiece of your outdoor living space.

When selecting plants to place around your waterfall, make sure to choose plants that can thrive in wet conditions, such as bog plants, rushes, and cattails.
