The 632-acre West Branch Forest Preserve in Bartlett is one of DuPage County's best locations to spend an afternoon fishing and boating. Deep Quarry Lake has a maximum depth of 40 feet, while Bass Lake's maximum is 30 feet. Both lakes contain bass, sunfish, channel and flathead catfish, carp, bluegill and crappie. The West Branch of the DuPage River also snakes through the preserve for 2.2 miles, offering scenic beauty for all preserve users in addition to the ample opportunities for fishing. West Branch's Deep Quarry Lake is also one of two Forest Preserve sites that allow carry-in boating.
West Branch has plenty to offer the general preserve user as well.
Preserve History West Branch Forest Preserve was purchased by the District for flood control during the 1970s. The preserve contains a reservoir that holds storm water and helps prevent flooding in the surrounding communities.
