Abstract: A combination skimmer and waterfall apparatus for use with a pool or spa. A skimmer is provided with a waterfall supply opening operable to deliver a flow of waterfall water into the skimmer interior at a location above the surface of the water of the pool or spa. A channel, preferably attached to a lid of the skimmer, directs the flow of waterfall water from the waterfall supply opening to a location proximate a top portion of the skimmer inlet opening to the pool or spa. The flow of waterfall water is then directed downward to form a pleasing waterfall effect in front of the skimmer. A source of light may be disposed within the skimmer interior to provide a back light for the waterfall. The width of the waterfall may be somewhat less than the width of the skimmer inlet opening. Waterfall operation and flow rate may be controlled independently from the normal recycle flow through the pool/spa pump and filter.
