Near Leola in McPherson County, South Dakota — The American Midwest (Upper Plains)
A haven for Waterfowl
When the last Glaciers receded from the Northern Great Plains 10,000 years ago, they left behind shallow depressions called "potholes." Some of these prairie potholes hold water temporarily, while others hold water year-round. These wetlands nurture a variety of insect and plant life, which in turn attracts great numbers of waterfowl (ducks and geese) and other wildlife. At least half of North America's waterfowl breed in the Prairie Pothole Region.
These prairie wetlands not only help produce the next generation of ducks and geese, they also help conserve water for people. Potholes reduce flooding by capturing and holding snowmelt. This helps recharge the groundwater and ensure that water is available for drinking and irrigation during drier periods.
Millions of shallow wetlands or "potholes," dot the grasslands of the Northern Great Plains in a landscape known as the Prairie Pothole Region.
