Location: Chinese Historical Garden, Portland OR.  The pond is located in a private garden and reflects the landscape giving depth to the view.  Materials: concrete, stone.  Dimensions:~40'x60'  The pond serves it's function quite well after being modeled after those found in traditional chinese gardens.  The idea was to provide the opportunity to learn about and feel as though you were in China and this pond adds significantly to that concept.  Ponds can be somewhat costly to maintain as they require constant up keep.
