How to Build a Backyard Pond in 10 Simple Steps

how-to build a backyard pondOne sure way to add a beautiful focal point to any landscape is to introduce a water feature. What about building a backyard pond? It will not only add diversity, it attracts beneficial wildlife. Adding a small pond with trickling water is an easy weekend project, plus you and your family will enjoy it for years to come.

Keep it Close

To get the maximum enjoyment from your pond, keep it close to your home. You want to see and hear it from your windows or patio area. Because you need electricity for the pump, keep the pond within close proximity to an outdoor outlet. Most pumps come with a 24-foot power cord; any further than that and you will need to extend your power lines.

Not Too Much Sunlight, Please

Ponds need sunlight to support beneficial wildlife and they prefer partial daily exposure. Too much sun can warm the water too much and allow algae to thrive. Avoid positioning your pond near large trees. Roots can damage your lining in their quest for moisture. Besides, fishing leaves out of your pond all the time is no fun.

Habitat for Fish?

Do you want a fish pond? You and your family may enjoy taking care of fish. However, they will need to be fed daily and the pond filter will need to be cleaned or changed regularly. It’s a decision to make before committing to be “fish parents.” If you commit, build in water depth to the pond, which is more critical than circumference. You need to dig a minimum of 18 inches for goldfish and three feet for koi in order for them to survive the winter.

The Soothing Sounds of a Waterfall

Consider adding a waterfall to your pond. Keeping the water moving and aerated helps keep algae in check and prevents mosquitoes from laying eggs. Flowing water also attracts birds and other interesting wildlife. Plus you benefit from the soothing sounds yourself.

Time to Start Digging

Now that you’ve decided where and how large of a pond you want, it’s time to call 811 to have someone come out and determine where underground gas and electrical lines might be. Once you’re clear of that, it’s time to start digging.

  • Mark the outline – form the shape you want with twine or landscape paint.
  • Excavate the area – if you are going for a lovely large water feature you may want to consider using a Bobcat or an excavator to make your digging easier.
  • Terrace the pond
  • Create a 3-inch wide area around the outside of your outline for the stone border.
  • Create a 1-foot wide shelf around the inside of the outline for aquatic plants. It should be about 8 inches deep from the edge of the pond.
  • Dig the bed of the pond a minimum of 18 inches deep, sloping slightly in creating the walls.

4) Dig a trench back to the power supply – this should be close to the deepest part of the pond since that is where the pump will go.

5)   Add an overflow trench at one end of pond – It should be about 6 inches wide and 1 inch deep to help channel overflow caused by heavy rains away from your pond.

6)   Prepare the Base – Add a 1 inch layer of sand followed by a 1/2” layer of newspapers around the entire base of the pond and terrace areas. The newspaper will help protect the liner from punctures.

7)   Line the Pond – Use a polypropylene flexible liner that can withstand UV rays, freezing temps, and is rated “fish friendly”. Cut the liner about 4 feet wider and longer than the pond dimensions. Center the liner in the pond and press it down, pushing tightly into the crevices.

8)   Fill the Pond – Begin adding water to the pond using a garden hose. While the pond is filling up pull the liner tightly to help remove creases. Get someone to help with this so that the extra liner you’ve left over the pond edge will not shift.

9)   Install the pump – Thread the power cord through a PVC pipe and place it in the trench leading back to exterior outlet and backfill. Place the pump in the deepest section of the pond while holding onto the other end of the hose.

10) Create a Rock Border – To hide the liner edge place rocks around the perimeter. The rocks need to interlock so they will not be loose and cause a safety hazard. Create easy access for wildlife by extending some of the rocks into the shallow water.

Jump Start Your Pond’s Ecosystem

Landscaping inside and around your pond is important for completely the look of your water feature. It helps to attract wildlife like birds and butterflies, and looks pretty to the human eye, too. To jump start your pond’s ecosystem add a bucket of water from a nearby natural water source. It will introduce millions of organisms and help keep your pond’s health in balance with nature.
