The Elk River Chain of Lakes Watershed, commonly known as the Chain of Lakes, is a 75-mile-long (121 km) waterway consisting of 14 lakes and connecting rivers in the northwestern section of the Lower Peninsula of the U.S. state of Michigan, which empty into Lake Michigan.
The watershed includes 500 square miles (1,300 km2) in Antrim, Charlevoix, Grand Traverse, and Kalkaska counties. The watershed includes a series of 14 lakes and interconnecting rivers. From the uppermost lake in the chain, Beals Lake in Echo Township, Antrim County, the water flows 55 miles (89 km) and drops 40 feet (12 m) in elevation. It has over 200 miles (320 km) of shoreline and almost 60 square miles (160 km2) of water surface.[1][2]
