🔍 Key Concepts

• Definition section of the Inland Navigation Rules (look for how "Great Lakes" is defined) • Geographic connection between the Great Lakes and the St. Lawrence Seaway system • Difference between rivers that feed into the lakes locally vs. international connecting waterways

💭 Think About

• Which of these rivers is specifically named or clearly included in the Inland Rules definition of "Great Lakes"? • Think about which river actually serves as the main outlet to the ocean for the Great Lakes system. • Are the Chicago and Calumet Rivers part of a canal system connecting to the Mississippi, or are they part of the official Great Lakes definition in the Rules?

✅ Before You Answer

• Verify the exact Inland Rules definition of "Great Lakes" in the definitions section (Rule 3). • Confirm which, if any, of these rivers is explicitly associated with the Great Lakes and St. Lawrence Seaway system in Coast Pilot or chart notes. • Make sure you are not confusing local harbor/industrial rivers with the formally defined Great Lakes connecting waters.
