Lake Catherine, IL

Lake Catherine is a Lake County CDP wrapped around a bay of Channel Lake in the northern Chain O’Lakes. The name points to the whole local arrangement: homes and roads sit around Lake Catherine, while the water connects into the larger Fox River chain. Illinois lake-management records treat Lake Catherine and Channel Lake as one shared water system, and state fisheries guides list Lake Catherine at about 149.5 acres. The surrounding story is glacial water followed by decades of shoreline development, marinas, fishing, and boat traffic. Lake Catherine has no traditional town center; it is a named waterside community whose identity comes from the lake, the channel, and the chain beyond them.
