My late husband, Peter, built a magical pond and stream creation in our back yard over 20 years ago using the old lath and plaster method. Our waterfront back yard had just the right slope for a running stream with waterfalls along the way. He dug an upper pond which connected to a lower pond with a winding stream that included mini rapids and several small waterfalls. The water was circulated back to the top using a pump in the lower pond which brought the water back to the upper pond via underground pipes. Unfortunately, several hurricanes damaged the plaster liner causing serious leaks. While still an interesting landscape feature, it has not been a working water feature for over a decade. I plan to resurrect it using flex seal paint to repair the cracks and look forward to the sound of gurgling water and the wildlife it will attract.
