How to Dig a Pond

Getting your pond going is more than how to dig a pond!

LAYOUT THE SHAPE Use a hose or rope to make the shape you require on the ground
surface.

Using this formula: Length x 2 + Width x 2 + Depth x 2 + Overlap x 2 to work out maximum size of your pond. Remember to keep within the size of your liner.

Depth: Depending on your location make the pond at least 18” (46cm) deep, 24-36” (61-91cm) is preferred in colder winter regions.

DIGGING THE HOLE to your shape, remember to leave shelves if you are putting plants in. The depth of the shelves will be dependent on the type of plants you intend to add. Check the plant tag for the correct application.

Make the sides vertical where possible to keep the pond volume high. One option is to add building sand to the bottom and sides of the pond surface, before installing the Pond Underlay to protect liner from damage. Be sure there are no sharp stones or tree roots in the pond walls.

Call 811 from anywhere in the country a few days prior to digging, and your call will be routed to your local one call center. Tell the operator where you’re planning to dig . Your affected local utility companies will be notified about your intent to dig and will send locators to your dig site to mark the approximate location of buried lines with flags or paint.
