🔍 Key Concepts

• Inland river chart symbols for aids to navigation and structures • How locks, river gages, and buoys are usually drawn or labeled on a chart • The purpose of a symbol with sectors or panels around a point feature

💭 Think About

• Ask yourself: On river charts, which items are normally shown as a small circle with divided or shaded sectors around it? • Which of the four choices is most likely to be associated with a fixed structure controlling water level and vessel traffic? • Consider how a simple buoy or sign would usually be depicted—would it need multiple black sectors around a circle?

✅ Before You Answer

• Check how locks are typically symbolized on your reference chart or legend • Verify whether mooring buoys or river gages usually have sectors or just a single simple symbol • Look at the chart legend section for regulatory/warning markers and lock structures to see which symbol uses a circle with black sectors
