A creative way to add water to your landscape is to build a beautiful cascading waterfall. Outdoor waterfalls are comprised of two major components. One is the cascading structure for the waterfall itself and a pool that the water falls into. While you are busy mulling over your design options, you should not forget to get the correct parts that are designed for cascading falls & spillways. At Everything Koi, we carry a large selection of products for cascading falls & spillways.
