I've posted shots of parts of it here before, but here's the global view showing the whole thing. It's maybe 20' long and up to 5' wide at the waterfall end.
I dug it, laid the liner, and did all the stonework...with the help of some very good articles/books on doing it yourself. Plus Lilypons, the original water garden supplier, is nearby, so that's where I got my original equipment, plants, and most importantly, how-to advice.
Sitting out there is instant serenity.
