In addition to the common types of garden fountain on the market there are also other styles of water features available, namely waterfall and pond varieties. Waterfalls and ponds function differently then fountains do and they direct water in unique ways which are specific to each style. Garden Waterfalls Garden waterfall styles are a replica of naturally occurring waterfalls in nature. These in a true sense are genuine waterfalls, but they have been built specially for a particular location and in a size and style that reflects the surrounding garden and preference of the owner. Waterfalls for the garden can be built of entirely natural materials or man made ones depending upon the effect to be achieved. A fine example is a ledge where stones or boulders have been placed underneath, below which is an area that can hold water to act as a fountain pond. Water can be made to flow over the ledge and down the stones and cascade into the lower pond section with this arrangement. The water will need to be pumped from the pond back to the top of the ledge using a submersible water pump and underground tubing since there will probably not be a naturally occurring water source present. More modern style waterfalls follow this same principal. Modern styles can be made of concrete and usually have flat surfaces and straight lines and look more spartan in nature then the stone or natural cliff ones do.
