I am planning to dig a new pond for ducks. How big should it be?

Size is not as critical as many people think, and very small pools can attract a lot of wildfowl. However, shape and depth profiles can be critical. Also, requirements vary from species to species. Diving ducks, for example, will feed in water several metres deep, while mallard can only upend to depths of about 45 cm. Getting the whole design right, and fitting it into the local landscape is critical to success, and a visit from your  Game & Wildlife Conservation Trust's local advisor is the way to be sure that you will get the most out of your new pond.
