Big Woods

Big Woods currently stands as an undeveloped, natural area comprised of open fields, natural wooded areas, restored wetlands, and ponds. Indian Creek runs through the preserve, and Poss Lake offers fishing opportunities. It also is home to numerous waterfowl and fishing bird species such as mallards, Canada Geese, great blue herons, great egrets, and hooded mergansers. Migratory species such as Sandhill Cranes have also been spotted. Big Woods is adjacent to the Batavia Spur of the Illinois Prairie Path.


Anglers can try their luck fishing at nine-acre Poss Lake. All persons 16 and older (except legally disabled persons) are required to have in their possession a valid Illinois sport fishing license. All anglers must follow District and state regulations.
