The Chain O'Lakes is a waterway system in northeast Illinois composed of 15 lakes connected by the Fox River and man-made channels. Encompassing more than 7,100 acres (29 km2) of water, 488 miles (785 km) of shoreline and 45 miles (72 km) of river, the Chain is the busiest inland recreational waterway per acre in the United States. Located on the border of Lake County and McHenry County, about an hour's drive from the cities of Chicago, Milwaukee, and Rockford, the lakes are popular with boaters and fishermen drawing weekend crowds of 30,000 and holiday crowds of 100,000 people. Additionally, the Chain O'Lakes includes Chain O'Lakes State Park which borders three lakes at the Northwest corner of the system. The Fox Waterway Agency, a special local governing body, is responsible for oversight of the Chain O'Lakes.
The Chain O'Lakes is composed of ten lakes connected by the Fox River and another five lakes by small canals and channels (with limited access). Of the ten lakes connected by the Fox River, three of the lakes are natural lakes. The three natural lakes are Grass Lake, Lake Marie and Nippersink Lake. The other seven lakes connected by the Fox River are Bluff Lake, Fox Lake, Pistakee Lake, Channel Lake, Petite Lake, Lake Catherine and Redhead Lake. The remaining five lakes of the system are Duck Lake, Long Lake, Spring Lake, Dunns Lake and Brandenburg Lake.
