At 0230 on 13 August, you are at mile 610.5 AHP when you see about a mile ahead lights on the water near the left bank. What might you see when you come abreast of these lights?
• Western Rivers mile markers and how to use the river chart index • How river terminals, dikes, and spoil areas are labeled on charts • Difference between fixed structures, dredging operations, and buoy markers
• Look at what is usually shown at or near mile 610.5 AHP on a Western Rivers chart – is it a terminal, dikes, dredging area, or recreational facility? • Think about which of these choices would most likely have lights close in near the left bank at night used as a warning or marker for navigation hazards. • Consider which options are typically marked by buoys versus fixed lights/structures or temporary operations like dredging.
• Verify what is charted at approximately mile 610.5 AHP on the appropriate river (use the chart index and mileage tables). • Check whether Hurricane Point or any named dike field appears near that mile mark on the chart or in the river listing. • Confirm which of the listed facilities or hazards are usually associated with a line or cluster of lights close to the bank to mark a hazard or restricted area.
