Question 22 RVR05 - Master of LT 100 GRT

The Correct Answer is C ### Explanation for Option C (Correct Answer) Option C, **The St Lawrence River to Trois-Rivieres**, is the correct answer because this area is explicitly *excluded* by the eastern boundary definition of the Great Lakes under the Inland Rules of the Road. The Inland Rules (33 CFR § 83.02(a)) define the eastern limit of the Great Lakes system as "as far east as **Montreal**." Trois-Rivières is located significantly downstream (northeast) of Montreal on the St. Lawrence River. Therefore, the waters of the St. Lawrence River extending past Montreal to Trois-Rivières are outside the geographic area covered by the Inland Rules' definition of "Great Lakes." --- ### Explanation of Incorrect Options The other options are incorrect because they are specifically defined or generally understood to be included within the scope of "The Great Lakes" as defined by the Inland Rules, which cover the Great Lakes and their connecting and **tributary waters**. **A) Portions of the Calumet River:** Incorrect. The Calumet River is part of the extensive tributary and connecting waterway system that feeds into Lake Michigan and is therefore included under the Inland Rules definition. **B) Saginaw Bay, Michigan:** Incorrect. Saginaw Bay is a large, defined part of Lake Huron and is necessarily included in the definition of the Great Lakes. **D) Portions of the Chicago River:** Incorrect. The Chicago River is a crucial part of the waterway system connecting to Lake Michigan and is considered one of the Great Lakes' connecting and tributary waters, making it subject to the Inland Rules.
