Step 1: Initial design
Step 2: Supplies
1 Pond Kit. It includes a pump and a mechanical filter, 3 underwater lights, 12'X 9' pond liner, a little fish that spits water, and 3 different fountain heads. Paid $79 at my local Meijers store. If you plan on adding fish to your pond, you will need a "biofilter" to remove the fish waste. This filter only filters out large particles, not bio-matter.
For the contruction of the pond itself, I bought:
10 8' 2X4's (I had them cut in half at the hardware store so they would fit in my car)
2 pieces of 1/4" plywood, 2'X 4'. You could use one larger piece, but again, I have a small car.
2 pieces of 1/2" pine 4'X 16", for the facing. I only bought 2 because I planned on putting the pond in a corner.
4 pieces of 1/2" poplar 4'X 4" to go around the top.
1 pound of 3 1/4" nails.
2 30 pound bags of river stones. Make sure you get "prewashed or prescreened" stones for pond use. Regular landscaping stones are often very dirty.
Stain and finishing supplies.
Choose the grade of wood according to how you plan on finishing your pond. I chose some good stain grade wood, but you could get cheaper "paint grade" if thats what you plan on doing. All this stuff was from Lowe's. Wood and supplies: $120

Step 7: Finishing it up, and End Notes
One final note:
I'd like to thank my wife for leaving me, so that I may spend my time doing fun things like this, and enjoying myself fully. :-)
