~Man Made to Perfection~! At Cheekwood this stream was created to move water from the upper koi ponds nearer to the Mansion, to the lower and much larger ponds, and it is as realistic as it can be! In fact it could fool you, if you did not know it was all man made. At the bottom of it all, they pump all the water back up to the top pond to begin it's journey again. Wouldn't it be lovely?
