McDowell Grove Forest Preserve

McDowell Grove spans 465 acres of mature woodlands, open fields, and floodplain forest along the West Branch DuPage River in Illinois.

The forest preserve housed a Civilian Conservation Corps camp from 1934 to 1943, where workers constructed bridges, picnic areas, and a limestone dam.

During World War II, the area transformed into a military facility where students received specialized training in radar technology and communications.

The preserve features 7 miles of trails for hiking and biking, plus a 22-acre Mud Lake where visitors catch catfish, bass, and bluegill.

The West Branch DuPage River restoration project modified the original dam to create improved water flow and enhanced aquatic habitats throughout the preserve.
