The 839-acre Lake Renwick Preserve was acquired between 1989 and 2010.
The preserve is part of the Lily Cache Creek preservation system, which conserves approximately 1,000 acres.
A 320-acre portion of the site was dedicated as an Illinois Nature Preserve in 1992. This dedication provides permanent protection for the natural resources at the preserve.
The Heron Rookery Nature Preserve is one of three access areas to the preserve, with Copley Nature Park and Turtle Lake Access, both in Plainfield, serving as the other entry points.
Hundreds of people visit the Heron Rookery Nature Preserve each year to be dazzled by the nesting herons, egrets and cormorants. Activity doesn't stop when the nesting season ends. Lake Renwick is also a hot spot for bald eagles, American white pelicans and hundreds of winter waterfowl.
