East Branch

The 525-acre East Branch Forest Preserve in Glendale Heights is largely a natural wetland along the East Branch of the DuPage River with lakes, marshes and wildlife habitats. It is an excellent place to observe grassland birds, shorebirds, and waterfowl, including spring and fall migrants.

In addition to recreational opportunities, the preserve provides valuable benefits to the community in the form of storm water control and improved water quality. One 0.8-mile trail and several unmarked footpaths allow visitors to observe everything from white-tailed deer and coyotes to great blue herons, sandhill cranes, and migrant waterfowl.



A picnic area is located at the Glen Ellyn Road entrance. Ground fires are prohibited, but visitors may bring their own grills and use the on-site hot-coal disposal containers. For everyone’s convenience, East Branch offers portable toilets near both parking lots.


The 15-acre Rush Lake has a maximum depth of 20 feet with little vegetation and steep gravel shores. The 5-acre Sunfish Pond has a maximum depth of 25 feet. Both feature largemouth bass, channel catfish, crappie and bluegill. Carp and bullheads also live in Rush Lake’s waters.

For those who would rather fish moving waters, the East Branch of the DuPage River winds through the preserve and offers anglers largemouth and smallmouth bass, crappie, channel and flathead catfish, and northern pike. Anglers should note that fishing is not allowed in the off-leash dog area.

Anglers 16 and older who are not legally disabled must have valid Illinois sport fishing licenses in their possession. All anglers must follow all District and state regulations.
