You can use any excess liner to trim and place under streams and waterfalls that you’re building, or you can save it to use later. So dig the hole first, then measure for the liner.Īlways buy a liner that is slightly bigger than you think you will need. It is very difficult to pack ground back into the pond to make the pond smaller. You don’t want to find out that the hole you spent hours digging is too large for your pond liner. Here are two good rules of thumb to calculate liner size: Unlike pre-formed ponds, flexible liners conform to any shape hole, and most come with a 20-25 year warranty. Offers the most options in terms of creating the shape and size of your pond, stream or waterfallĮasy to install. These materials are very popular for the following reasons: Check with the dealer to ensure the material is safe for fish.
These are well-suited for both applications, although you cannot alter the shape.įlexible Liner Ponds: These are constructed of 45ml EPDM and PVC. An above ground installation takes a little more time and care when installing to ensure the pond form is stable and balanced. For in-ground applications, you simply excavate the shape of the pre-form and drop it in. Pre-formed ponds: These are generally for smaller ponds ranging from 50 gallons up to 200 gallons. Liners come in weights ranging from tear-resistant, lightweight liners to heavy-duty EPDM liners.Ĭoncrete Ponds: This option is not used often for residential ponds due to the cost in materials and labor and the eventual issue of cracking.

There are three basic methods to install a garden pond: concrete, pre-formed ponds and flexible liners. Also, ponds intended specifically for Koi should be closer to three feet deep to allow room for these larger fish to swim freely. For areas with very cold temperatures, such as upper New England or the upper Midwest, you should make your pond 30 inches or deeper so that it does not freeze completely to the bottom. In most parts of the country, a pond for goldfish and plants of 18 inches - 24 inches is generally deep enough for fish to survive in the winter. These waste lining material, reduce water capacity and create stagnant areas where solid wastes can accumulate. For informal gardens, ponds can have a more natural, free-form shape bordered with stones of various sizes and shapes. Geometrically shaped ponds with bricks or flat paving stones are a nice complement to formal gardens. Ponds this size will be more ecologically balanced, retain more stable temperatures, and provide greater movement for fish. Make your pond at least 30 square feet with a minimum depth of 18 inches. Also, make sure your garden hose is long enough to reach your pond.ĭesirable size and shape: Once you have decided on a location, you can design the size and shape of your pond. Proximity to electricity and water: Be sure your pond is close to a GFCI (Ground Fault Circuit Interrupter, an outlet) electrical source. Conversely, shade trees drop leaves and blossoms into the pond, robbing the water of oxygen as they decompose. Excess sun causes an overabundance of algae growth and green water. Take advantage of sloping terrain by adding interest with cascading waterfalls, streams and tiered landscaping.Īmount of sunlight: Five to six hours a day is ideal. The sounds created by waterfalls and streams are soothing and can help eliminate traffic noises.įlat ground and sloping ground are both fine: A pond does not need to be on flat ground. Next to patio or deck: Having your pond next to your deck or patio is great – since these are areas for relaxation and entertainment. Orientation of waterfall: Be sure to orient your waterfall so that it is visible from the place you will enjoy it most. Viewing from windows: Since most of us spend more time inside our homes than outside in our garden, it makes the most sense to locate the pond where you can see and enjoy it from the window(s) or room(s) you frequent most, such as your kitchen, sun room, family room or deck.
