Building a pond for your garden is not nearly as complicated as I first thought it may be. I built a pretty little pond in my front yard just off the front walk and next to the porch. Here, I could sit and enjoy the sights and sounds. And I did it in a weekend without ANY professional help! Here’s how to build a pond, and tips on easy maintenance as well. Plus, we have other bloggers’ DIY pond tutorials as well, with everything from a DIY Koi pond, to a patio pond idea! Just in case you are looking for something different for your backyard water feature!
How to Build a Pond
DIY Pond Tutorial
Step one– Rough out the area the size you want your pond. A pond can be as large as you wish, but I chose to make mine approximately 4×8 feet. Check with your local code if you plan to place the pond in an unfenced area…some towns limit the depth of the pond if it is unfenced, usually to 12 inches.
Decide if you just want a decorative pond, or a complete water garden with live plants and fish. I chose a decorative pond with a fountain feature, but keep in mind a water garden will require a deeper pond with more maintenance.
Step two– Once you have the pond shape marked with either paint, chalk or a spare hose laid out on the border, its time for the hard work! Dig! My original pond was 18 inches deep to allow for some goldfish my children wanted. Goldfish are tough as nails, but keeping up with the algae was tougher! When doing some repairs the following spring, I removed the fish and backfilled my pond until it was only 12 inches deep. Whatever you choose, excavate the pond to the desired depth and try to keep the sides as vertical as possible. This will make it easier to hide the liner later.
Lay some material in the bottom of the pond to cushion the liner against rocks, sticks and other items likely to punch holes. Good low budget ideas are newspaper, old carpet or even sand.
Step three– Purchase a pond liner from your local supplier or discount store. Measure your pond depth x 2 and add to the length plus 2 feet- that is the length of your liner. Your pond depth x 2 added to the width plus 2 feet- that is the width of your liner. The extra 2 feet allows for fitting and cutting away of the excess.
Lay the liner over the pond and fit into the bottom, fill halfway with water and allow to sit several hours or overnight to settle the soil. Trim the liner to hang just 3-4 inches over the lip of the pond…that few inches is important, better to trim too little than too much, you can always go back later and re-trim. If you are going to add a fountain pump, place it in the pond now.
Step four– Now you want to hide the edges of the pond liner with rocks. Flagstone in my part of the country is pretty expensive, so I figured out a way to get the flagstone look for only $25. I picked up a case of slate floor tiles, and used a hammer to break them into pieces. I lay the slate over the lip of the pond with the broken side facing the pond center. Then I hid any smooth edges of the tiles with river rocks from my yard, simply layered on top of the slate. You can also use the local rocks to hide any excess pond liner as well. Plug in your fountain pump, and set it onto a brick to achieve the right height if necessary. Make sure you have a GFI outlet to plug into, if not, consider a solar pump.
Step five– Add plants and accessories around the pond to make it a welcoming place for all your visitors! Be sure there is seating nearby. A birdfeeder in the nearby trees will ensure a steady supply of feathered friends to enjoy your pond oasis! First two photos in this tutorial were from ‘EHow‘, this one is my actual finished pond. You can build a pond without breaking the bank!
There are many algae controls available for those not interested in learning the complexities of creating a natural biological environment in their water garden. Even discount stores carry such supplies the garden section. A small amount of bleach will also keep the water clean, though you must be careful to use small amounts. Avoid this method if wildlife frequents your pond. These backyard pond ideas are fast, easy and a showstopper that will add real value to your garden and your home.

Hi, your tutorial is amazing. Just needed info on how to clean the pond. I mean do we need to make an outlet for the water to flush out in order to refill it while cleaning?
Regards from the Himalayas.
How can we get rid of mosquitoes and algae??
Pond supply stores have additives for both those problems!
Chemicals are not the answer! Photos of the koi pond are totally green on this site and indicate a lack of knowledge regarding filtration. A correctly built pond doesn’t have to be emptied twice a year.
what maintenance one needs to do to keep the pond looking new especially to keep out algae.
There are additives that you can buy wherever they sell pond supplies that fight algae, and it also helps to position the pond in the sun. We clean ours out and refill it in the spring and fall… Hope that helps!
I just found what is called a bird bath fountain pump on Amazon to put in the middle of this. I have not built it yet but its in the plans
