Presenting my back-yard pond made of recycled and reclaimed palette wood (well, a significant part of it, at least). I started by digging out 2 tiered hole (7 by 5.5 foot and 2.5 foot deep) then installed contractor grade wood reenforced walls as the foundation and lined it with a cotton base-coat and a 15 by 15 foot 1/32 inch waterproof foil. the pond itself consists of multiple wall segments, each with even planks (resembling mid-century kitchen wainscoting) secured to wooden studs via smooth headed corrosion proof nuts and bolts. The segments were then coated with waterproof, environmentally safe (and very expensive) yacht-hull enamel. Then the final pond structure was assembled on the lawn adjacent to the hole and lowered (extremely carefully) into place. Prior to filling the pond with water, 400 pounds of pea pebbles were added to blanket the pond floor and planting shelf. The running boards and seating shelves are solid ceder planks waterproofed with earth-friendly classic wood-hull boat stain. the last step was to add the landscaping (including these really cool blue glow pebbles), the whiskey barrel, waterfall pump (950 gal/hr) and 575 gallons of water (recycled mason jar lamps light up the water feature at night).
