DIY Hillside Waterfall: 1,500 GPH Pump and Natural Stone

Pump Size

For a 4–5 ft vertical lift on a steep bank, a 1,500–2,000 GPH pump (e.g., Little Giant, Tetra) provides a natural sheet flow.

Construction

• Use existing rocks and plants.
• Lay EPDM liner on the slope, tucked into soil.
• Dry-stack stones for multiple small drops.
• Plant ferns/mosses in crevices.

Mindset

You'll always want to tweak it—that's the joy of ponding.
