Find the area for your waterfall---a corner of the yard or garden that has multiple vantage points from inside the house is ideal.
Dig out the catchment pond of the waterfall, 1 foot deep should be enough. The pond can be as large as you like it, but 5 feet across is an easy, manageable size.
Dig out a small channel in the edge of the pond on the side where the waterfall will go. Make this channel around 1 inch wide for the pump hose to go in, carrying the water unseen from pond to the waterfall.
Line the pond area with the pond liner, making sure the channel is still accessible. Put river stones around the edges of the pond liner, holding it in place and creating a more natural look.
Place the water pump hose in the channel, with about 3 inches sticking out into the pond area. Lead the hose to where the water pump will be.
Place the largest rocks for the waterfall at the base, creating a platform to build to waterfall on top of. These rocks should be on the edge of the pond.
Place the pump where the hose ends, fixing the hose to the nozzle on the pump. Attach the hose for the waterfall as well. Lay more stones to build the waterfall, threading the waterfall hose up through the center as you go.
Lay stones laterally, resembling a natural rock formation---if the rock is simply piled one on top of the other it will just look like column of rock, not a real waterfall.
Test out how the water will flow over the waterfall using the garden hose to run water down the stones. Adjust stones so that the water is flowing into the catchment pond, and so that an aesthetically pleasing flow is created down the waterfall.
Cement unsteady stones in place. The whole structure shouldn't need cement, but add cement in key areas, if necessary, only after you are happy with the design. For mixing and drying instructions, follow the directions on the cement manufacturer's label.
Fill the pond with water, arranging plants around the sides of the pond, and even on the waterfall. Turn the pump on.
Things You Will Need
- Faux or real rocks, variable sizes
- Water pump and hose
- Pond liner
- River stones
- An electric pump is used, so the location of the waterfall needs to be within a reasonable distance of a power source.
- Fish will live happily in a waterfall pond.
