Dig a channel to direct the flow of water.Garden waterfall image by Allen Stoner from Fotolia.com
Dig a channel from top to bottom to direct the flow of the water. The basin at the bottom should have a berm shoulder to collect the water. It must be at least 24 inches deep. If necessary, use the extra dirt at the opposite end to create an even steeper waterfall. - 3
Wet down the sand and smooth it with your shovel.Garden image by mhiser from Fotolia.com
Pour a layer of sand in the channel, wet it and smooth out with shovel. - 4). Spread the pond liner over the channel and trim it to twice the width and a bit longer than your waterfall. Spread the liner smoothly over the sand, taking care to not punch a hole in it.
- 5). Hook the flexible pipe to the pump and filter. Attach the electrical cord. Run the pipe up the channel to the top of the waterfall. Fill the catch basin with gravel and place the pump at least 2 feet below the surface.
- 6). Position the stones. Think about a stream bed and try to recreate that look with small stones. Use larger stones at the outer edges of the pond liner. Create pockets with the rocks where the water can pool before it cascades down to the next level, and build in twists and turns to give your waterfall an even greater splashing sound.

Fish love the shade provided by water lilies.Water lilies in lake image by L. Shat from Fotolia.com
Add plants.Your waterfall should be equal parts water, rock and vegetation. Add water-loving plants to cover about 65 percent of the water area. - 9
