Great Lakes,

Great Lakes, for the purpose of calculating service requirements for an endorsement, means the Great Lakes and their connecting and tributary waters, including the Calumet River as far as the Thomas J. O'Brien Lock and Controlling Works (between miles 326 and 327), the Chicago River as far as the east side of the Ashland Avenue Bridge (between miles 321 and 322), and the Saint Lawrence River as far east as the lower exit of Saint Lambert Lock. For purposes of requiring MMCs with rating endorsements, the connecting and tributary waters are not part of the Great Lakes.
