Pond Shape

The shape and surface area are generally down to personal preferences but it is always best to create a shape which allows the “natural” flow of water. Using complex shapes should be avoided to alleviate construction difficulties and create less folding and wastage of pond liner.

It’s always a good idea to take a rope or hose and spend time creating the shape of the pond you desire. It may be that a pre-formed pond will fit your requirements.

Alternatively- measurements can be taken and the correct liner size calculated. Using the simple step by step guides throughout this site will help you to plan and budget the amount of materials you will require. See "Calculating Your Liner Size" page.

If you are considering a stream or waterfall, it is wise to keep it in proportion to the size of the pond, as a small pond with a large waterfall could suffer problems such as turbulent water flow or varying water levels when the pumps are switched on. These factors are undesirable for a balanced pond with plants and fish, but would be fine if you are only wishing to create a waterfall feature where the pond is purely a reservoir for the feature.
