Abstract
A flat ribbon-shaped waterfall for a portable spa is caused to flow out of the top rim or top side of a spa. A narrow elongated spout forms the output end of a plenum chamber that has a water inlet. The plenum chamber is constructed to baffle surges in the inlet water flow. A light source is placed close to the mouth of the elongated spout to light the ribbon of water flowing from the spout in multi-color, if desired.
