Barringer Slough in Iowa, a remnant of the extensive prairie wetlands that once covered the region.

The Prairie Pothole Region (PPR) is an area of the northern Great Plains and midgrass and tallgrass prairies that contains thousands of shallow wetlands known as potholes. These potholes are the result of glacier activity in the Wisconsin glaciation, which ended approximately 10,000 years ago. The decaying ice sheet left behind depressions formed by the uneven deposition of till in ground moraines, and melting ice blocks which created kettle lakes. These depressions filled with water, creating the potholes.

More than half of the potholes have been drained and converted to agriculture.^[1]^[2] Pothole loss is 90% or more in places.^[3] Those potholes that remain are important habitats for migratory waterfowl and other wildlife, supporting more than 50% of North America's migratory waterfowl.^[2]
