An ideal water feature to add to your garden pond is, a waterfall.This is easily accomplished by using pre-fabricated moulds. They come in various shapes, sizes, colours and designs.
These items can be purchased from most aquatic centres.

During the summer months, there is nothing more relaxing than when you are sitting in your garden, drinking a nice cold larger and reading a book, hearing the water in the background as it gently makes it's way down the waterfall and back into the Koi pond.

These moulds can be placed in line, in order to form the length and shape you wish your waterfall to flow.
You can use as many moulds as you like, it all depends on the length of water feature you would like to create.

The first mould you use should be positioned closest to the pond, with the front protruding over the pond edge by 3 to 4 inches.

The second mould should be placed higher, and, to the rear of the first. Repeat this until you have achieved
the length and shape desired.

An added advantage with a waterfall flowing back into your pond is,as the water flows back into the koi pond it generates oxygen,which all fish require.
