I bought this at Home Depot, which also offers a "materials" service from the same help desk in each store that will help design a deck and print out all the needed materials.
This offering appears to be "best in class." I found the following extremely helpful:
1) Up front discussion of the hardest part, creating a balanced ecosystem with balanced chemistry. If you do nothing else, let county water sit in a tub overnight to dissipate the cholorine, before putting it into a live environment.
2) Complete coverage (chapter 3) on materials and equipment. This is a lot easier than most might think, but it *does* require hard work if you get much above a pre-fabricated form. Rocks are *heavy* and you need a LOT of them--three times as many as you might think.
3) Superb photographs and drawings, checklists, and at the end, a list of water resources.
I am struck by how many people seem to be turning not only to waterfalls, but to full-up water gardens. While perhaps difficult to support in drought conditions, my wife and I have had a small pond for years and now want to move up to a waterfall and 4 times larger pond, and this is the book that has made that possible.
If you are discouraged or do not feel up to the challenge, I do recommend a very simple water feature, just a wash-tup and one of those spouting lion heads, or the bamboo trio. For under $100, you can get a water feature that is ready to go and plugs in, and for under $75 you can get a world class wind-chime. Add an outdoor clay fire pot with chimney, and you have the three key ingredients: water, wind, and fire.
