Constructed ponds of all shapes and sizes dot the American countryside, for many different purposes: irrigation, fish, recreation, nature study, and real estate value, among others. A pond creates its own microenvironment, bringing peepers, dragonflies, and cool morning mists to the landscape. Yet mistakes in pond management can affect people and wildlife downstream and downhill: water does not recognize property boundaries. This book, developed by faculty from Cornell and Penn State, addresses construction, water chemistry, aquatic weed management, fish stocking, wildlife (wanted and unwanted), maintenance, safety, and more. 76 pages, 2007.
