As promised, here are some pictures of the pond. Don't laugh, I had no prior experience in pond-making. And yes, the waterfall is lame, but it's enough to airate the water. Notice how green it is right now.
This is what you see as you walk toward my backyard.
A closer look.
And closer.
Even closer.
And finally...
The whole thing cost me about $250 and many hours of manual labor.
