Building a duck pond is simple project that can make an attractive addition to any garden. It is also a way to use up extra space if your garden is large, if you want to attract wildlife or you are looking for a hassle-free feature. However, building a pond is not always cheap. To ensure your pond is cost effective, keep it small so you can dig the space yourself and stick with simple features.
Choose the location of your pond. Choose a low area of grassy land so rainwater can run in, according to the Backyard Pond Guide website. If you prefer, you can add water with a hose, but if you are trying to save money, using natural rainwater to fill the pond is the cheaper option.
Decide on the shape of your pond and mark it with a piece of old rope or spray paint. Grass marking paint is available from most garden stores or online. To build your pond cheaply, use old rope you already have on hand.
Dig the soil from your chosen area. According to Washtenaw Conservation District's website, waterfowl duck ponds should be 3 to 5 feet deep and no deeper. Ensure the bottom of the pond is even by checking it with a spirit level. Leave the banks of the pond approximately 1 foot higher than the base of the pond so the sides of the pond gradually slope down from the edge of the pond to the flat base.
Cut out a piece of vinyl pond liner and place it in the bottom of the pond so that it covers the base of the pond and the banks. Tuck the edges of the liner directly into the soil in the sides of the pond. You should no longer be able to see the edges of the liner. This is just aesthetic, but your pond will look tidier. Vinyl pond liner is inexpensive, but if you want an even cheaper option, the Water Features Guide recommends a black plastic sheet, available from local hardware stores.
Wait for your pond to fill with water or add water from a garden hose. Waiting for rainwater to naturally collect in your pond is the cheaper option, but it could take a long time. Use a garden hose if you wish to fill the pond quicker.
