What color buoy indicates a dredging area?

A yellow buoy indicates a dredging area. Yellow is used in the U.S. Aids to Navigation System to mark specific hazards or areas where special caution is required, such as dredging operations. The color serves as a warning to mariners that they should maintain a safe distance and be mindful of potential hazards in the vicinity.

In the context of navigation and safety at sea, it is essential for boaters to recognize and comply with the markings of these buoys to prevent accidents or collisions, thereby ensuring both their safety and the continuation of dredging activities. By identifying yellow buoys, mariners can effectively navigate around dredging zones, which may involve underwater equipment or significant alterations to the seabed.
