Once part of an extensive wetland network that included nearby Lake Abram and Lake Isaac, Fowles Marsh was historically drained for onion and celery farming. Today it has been restored to a large open marshland with mudflats that are inviting to several species of waterfowl.
Fowles Marsh is located along the Lake to Lake Trail between Bagley and Fowles Roads. Fowles Marsh is most easily accessible by trail via Lake Isaac Waterfowl Sanctuary. No parking is available to Fowles Marsh.
