Under the U.S. Aids to Navigation System used on the Western Rivers, which is TRUE of the aids to navigation lights on the right descending bank?

🔍 Key Concepts

• Western Rivers System and how it differs from the standard U.S. lateral system • Meaning of the right descending bank on a river (in relation to the river’s flow direction) • Color characteristics of lights marking the right bank versus the left bank under the Western Rivers System

💭 Think About

• First, picture yourself traveling downstream on a Western River. Which side is the right descending bank? • Think about the lateral marks you would see along that bank: what colors are normally used for that side in the Western Rivers System, and how does that translate to light colors? • Ask yourself: are Western Rivers lights restricted to a single color on that side, or can there be a combination of colors, and if so, which ones?

✅ Before You Answer

• Confirm how the right descending bank is defined: always in the direction of the current/flow of the river • Review which buoy and daymark colors are used on the right descending bank in the Western Rivers System, then connect those to their typical light colors • Verify whether white lights are used on fixed aids (like ranges or structures) in addition to the standard lateral light color on that bank
