The name 'Saganashkee' is derived from a Potawatomi term associated with the British, historically used to refer to English traders in the region.
The slough was significantly altered by mid-20th-century engineering projects to manage water levels and create permanent recreational basins.
The preserve is located atop the Valparaiso Moraine, a glacial feature that accounts for the hilly topography surrounding the water.
It is part of a larger ecological restoration project focused on reintroducing native savanna species to the surrounding forest interior.
The Palos Preserves, where this site is located, is designated as an Audubon Important Bird Area due to its significance for migrating raptors and waterbirds.
Saganashkee Slough Woods is a designated Forest Preserve of Cook County featuring expansive wetlands and mature forest habitats. It is primarily known for its extensive slough, which serves as a significant stopover for migratory waterfowl and provides diverse opportunities for anglers. Hikers can access miles of unpaved trails that traverse through oak woodlands and rolling terrain typical of the Palos Hills landscape. The site is a core component of the broader Palos Preserves network, which contains some of the largest tracts of contiguous forest in the Chicago region. The slough acts as a natural retention basin and habitat corridor, supporting a wide variety of native flora and fauna. Visitors utilize the area for passive recreation, including birdwatching, trekking, and fishing from designated shoreline points.

Bring waterproof footwear, as trails near the slough margins frequently become muddy or flooded during high-water seasons.
Use insect repellent during the summer months, as the wetland environment creates a high density of mosquitoes and ticks.
Consult the Forest Preserve of Cook County website for current trail closure notices before arrival.
Do not attempt to swim in the slough, as water conditions are managed for wildlife and contain hidden submerged obstacles.
Open daily from sunrise to sunset; portions of the preserve may close seasonally for ecological controlled burns or trail maintenance.
Stay on marked trails to protect sensitive wetland flora and pack out all trash to maintain the preserve's ecosystem.
