Vermilion Co. Audubon Society, and the Outdoor Heritage Foundation, the first system of dikes were constructed in the early 1980's. Since then a Ducks Unlimited grant was procured to flood more acreage. Wetlands are one of the most endangered habitats throughout the country.
Wetlands continue to be drained to make room for future development.
The Kennekuk Marshes are a system of several connecting ponds that inundate nearly thirty acres of water during the spring rainy season. Water levels remain until waterfowl fledge their young in late spring. During the drought months, water levels may be reduced to under fifteen acres. The Kennekuk Marshes offer excellent wildlife viewing. Many species of ducks can be seen as well as Canada goose, great blue herons, egrets, and hawks.
