The lagoons were formed by a massive Depression-era public works project involving the hand-digging of channels by the Civilian Conservation Corps.
The water system is part of a complex flood control project designed to prevent the Skokie River from overflowing into nearby residential areas.
It is designated as a significant Important Bird Area (IBA) by the National Audubon Society due to its role in migratory stopovers.
The preserve's topography is a direct result of the last glacial retreat, which left behind low-lying depressions.
Some sections of the forest preserve incorporate restored prairie ecosystems to support local pollinator populations.
Skokie Lagoons consists of seven interconnected pools covering approximately 190 acres within the Cook County Forest Preserves. Originally a series of marshes, the lagoons were excavated by the Civilian Conservation Corps during the Great Depression to manage flood control and create recreational space. The preserve features over 15 miles of paved and unpaved trails suitable for hiking, cycling, and equestrian use. It is a significant regional hub for flatwater kayaking and canoeing, with dedicated launch points and equipment rental services available seasonally. The area serves as a primary bird-watching site, hosting diverse waterfowl, herons, and raptors due to its wetland habitat. Anglers frequent the waters for populations of northern pike, largemouth bass, and panfish. The site remains a core component of the Chicago Botanic Garden's surrounding ecological corridor. The lagoons are separated by wooded islands that provide nesting grounds for local wildlife.
The wooden bridges connecting the islands offer the most expansive views of the water and surrounding forest canopy.
Bring insect repellent as the wetland environment attracts significant mosquito populations during warmer months.
Use the dedicated boat launch areas to protect the natural shoreline from erosion caused by informal entry.
Check the Forest Preserves of Cook County website for seasonal water safety alerts or algae bloom reports before visiting.
Do not attempt to swim in the lagoons, as water quality is monitored for ecological use rather than human contact.
Rental facilities and launch docks are seasonal, typically operating from late spring through early autumn; the preserve grounds remain open year-round.
Stay on marked trails to protect sensitive wetland flora, pack out all trash, and keep dogs leashed at all times.
