The Preserve is a 519-acre property located about a mile south of the Goose Workshop. It is not currently open for any recreational or educational use. The Illinois Division is working to develop the property in keeping with the mission and vision of the Izaak Walton League of America.
From its beginning, the IWLA Endowment has supported Goose Workshop, formerly the Giant Goose Conservation Education Workshop, a volunteer-maintained conservation and recreation area in Illinois.
