How to Build Above Ground Ponds for Fish

If you want the joy of a koi, goldfish or other fish filled pond without digging into your lawn or garden, consider above ground ponds for fish. Building above ground ponds for fish can be easier than digging an actual water garden. The main focus is site preparation and sturdy construction.

Above ground ponds for fish can be just as permanent as their below ground cousins, and this permanence can be incorporated into the design features when deciding where and how to build your backyard pond.

  1. Plan where you want above ground pond for fish to be in your yard. This could be in your garden or on a deck or patio. Be sure the location is strong enough to hold up a pond and that the surface is flat and relatively smooth. Mark out the dimensions of the above ground pond for fish where you intend to build it.

  2. Stack up bricks or stones blocks as directed by the manufacturer in your rectangle, square or round shape. Use masonry adhesive, to attach them firmly to each other. If you are using timbers, stack them in the same shape and attach them to each other with brackets and bolts. You want to build a wall at least 1-foot high but preferably 2-feet tall if you want to keep fish in the water garden.

  3. Lay the flexible pond liner in the rectangular structure you just built. Smooth it out by folding the corners on themselves and overlapping the liner on the top layer of the above ground pond for fish wall. You can use adhesive to attach this as well.

  4. Use stones, more brick or masonry blocks or additional timbers to the above ground ponds for a fish wall. This will hide the edge of the flexible pond liner. Position the filter and pump and fountain apparatus in a hidden spot off to the side, if possible. Fill the pond with water and turn everything on.
