2007 Pond Numbers

One of the most important elements in duck breeding success is the amount of water present on the prairie breeding grounds. In 2007, total pond counts for the United States and Canada combined showed 7 million ponds, a 15 percent increase from the 2006 estimate. Pond numbers for Canada and the United States are also estimated individually.
