Hi, I've be interested in backyard water features for a while. Built them at both homes we've lived in. First one consisted of a 1.5m high rock waterfall that dropped into a lined creek flowing under an arched wooden bridge into an in-ground pond (approx 1,000 litres) that was inside a shade-house where we kept birds. Spent plenty of time just sitting and reflecting, listening to the sounds of water and birds. Current one is a bit less elaborate (downsized yard) - above ground pond with two sides of glass to enable view of plants, rocks and fish. Has a smaller waterfall sitting on edge of the wall in corner and pond has garden beds along the other two sides. Still getting pond established with plants and fish.
