waterfall and stream. The word "pondless" means that the reservoir for the water is underground where it is safe. The 4' high by 8' wide waterfall spills into a large landing area, and then travels down a narrow stream, around side of a lounging patio, and disappears behind evergreens into our pondless reservoir. This water feature gets winterized in December and starts up again in March. Every spring we come in to spruce up the plantings, adding perennials, annuals and mulch. www.deckandpatio.com
