This is part of the southwestern Louisiana Prairie Terrace; it is higher and not made of wetlands like much of the surrounding areas to the south and west of Lafayette. Lafayette does not suffer significant flooding problems, outside of local flash flooding. Lafayette has developed on both sides of the Vermilion River. Other significant waterways in the city are Isaac Verot Coulee, Coulee Mine, Coulee des Poches, and Coulee Ile des Cannes, which are natural drainage canals that lead to the Vermilion River.
