Mature woodlands, high-quality marshes, tallgrass prairie, clear-running creeks and a 65-foot deep lake are just some of the highlights of Big Rock Forest Preserve.
Siegler Lake is a premier feature of the preserve. Formerly a limestone quarry, the lake was formed when high floodwaters breached the banks of Big Rock and Welch Creeks in 1996, sending torrents of water into the quarry. The result of this flood event was a 32-acre lake, complete with fish and invertebrates that were swept in with the floodwaters. Subsequent fish habitat projects have been undertaken, and the lake supports a diversity of fish and aquatic wildlife.
Big Rock Creek, rated one of the best quality streams in Illinois, is home to freshwater mussels — indicators of high-quality habitat.
High sandy bluffs overlook patches of woodlands and prairies in the preserve, and a specialized wetland called a fen is fed by underground seeps on the southeastern portion of the preserve.
