Backyard Pond

Building a customized backyard pond isn't as hard as you think. This guide will walk you through the process.

Tip: Make sure to choose an area that gets a minimum of six hours of sunlight per day, especially if you plan to include plants that require moderate to heavy sunlight. Double-check with your local pet store if you plan to add fish to your pond.

• Press the liner into all gaps to ensure a proper fit.
• Leave at least a 10-inch overhang.
• Remove the liner and create the underlayment to provide additional protection for the liner. Two layers of underlayment are recommended.
