🔍 Key Concepts

• From step 8, the voyage is approaching Old River Control Structure; this question asks for a facility’s published dimensions, not a new position or course calculation. • Distinguish the lock’s usable chamber width and length from nearby structures or channel dimensions. • The attached illustration is only an abbreviations table; it defines ACOE but does not list lock dimensions.

💭 Think About

• Which source in the problem set would provide a lock’s chamber dimensions, and does the attached image contain those measurements? • Compare the four choices by both width and length; which pair matches the Old River Lock’s published specifications?

✅ Before You Answer

• Carry forward the downstream voyage and Old River area from step 8, but do not invent a new fix or use a distance from an unrelated earlier step. • Verify both dimensions against the applicable Army Corps of Engineers chart or facility information before choosing.
