🔍 Key Concepts

• Mississippi River channel dimensions in major ports such as New Orleans and Baton Rouge • Typical maintained project depth and width for deep‑draft navigation channels • How channel dimensions can change between different river sections or ports

💭 Think About

• Think about what size ships regularly call at Baton Rouge and what draft they require. • Compare which answer choices look more like deep‑draft, main shipping channel dimensions versus smaller river or harbor channels. • Ask yourself whether Baton Rouge’s maintained channel is more similar to the lower Mississippi approaches to the Gulf or to a smaller inland waterway.

✅ Before You Answer

• Verify the standard project depth (in feet) for the Mississippi River channel in the Baton Rouge reach from official sources like USACE (U.S. Army Corps of Engineers). • Confirm the project width (in feet) typically maintained for that same reach. • Eliminate any answer choices that seem too small for large ocean‑going ships that routinely transit to Baton Rouge.
