Resource Management - Wetlands

Historically, over 5,000 acres of the refuge were normally flooded in the spring and mostly dry by summer, primarily due to man-made drainage programs. To provide additional wetland habitat, a system of dikes (man-made barriers) and water control structures were created to help manage water levels. Water levels are carefully managed to provide a variety of feeding, nesting, brood rearing, and resting habitats for migratory birds and resident wildlife. Water levels are adjusted to mimic natural water fluctuations associated with unaltered wetlands and to provide the best possible wildlife habitat. These changes in water levels result in subsequent changes in wetland vegetation and ultimately provide the desired habitat.
