How to Make a Homemade Garden Pond

A garden pond will add design interest to your landscape and will also invite a new eco-system to your property. You can create a homemade garden pond for Koi, goldfish and aquatic plants like water lilies with materials from your local landscape supply and from online retailers. The filtration system is your most important purchase; systems vary considerably, so make sure to do your research and find the filter that will best suit your garden pond.

Step 1

Outline the location of your garden pond with spray paint. You can make your pond any shape you like; the outline will help you as you excavate.

Step 2

Excavate the area to fit the outline of your garden pond. The depth of the pond depends on your personal preference as well as your intended use for the pond. Koi ponds should be at least 3 feet deep, but 5 feet is better. Koi should have at least 1000 gallons of water to thrive. Water gardens only need to be 2 feet deep, but you should have at least 12-inches below the freeze line for your area. Create a 12-inch deep shelf around the perimeter of the pond for placing plants, if you like. You may also wish to create a bog shelf about 1 foot above the bottom of the pond.

Step 3

Remove any rocks, roots and other debris from the bottom and sides of the pond before you install the underlayment.

Step 4

Position the external pond filter system and dig a trench to the pond for the intake and the outtake lines.

Step 5

Place the pond underlayment in the excavated area. Place the pond liner over the underlayment. Try to minimize the wrinkles in the liner. Don't worry if you can't eliminate them, when you add water the wrinkles should flatten.

Step 6

Install the intake and outtake lines from the pond to the filtration system according to the manufacturer's directions.

Step 7

Install the large rocks around the outside perimeter of the pond to hold the liner in place and to add natural, visual interest to your pond. A layer of mortar on top of the liner covering the ground and between the rocks will hold them in place. Let the mortar dry.

Step 8

Fill the pond with water before you turn on the filtration system.
