What type of buoy indicates a dredging area?

Types of Buoys for Dredging Areas

Buoys used to indicate areas where dredging is occurring are not universally standardized and might vary by region. Typically, these would be special-purpose buoys with signs that signify they are marking a dredging area.

In the United States, the aids to navigation system uses orange diamond shapes to indicate areas where vessels should not go, such as dredging, underwater pipelines, or cables, and this might also appear on buoys near dredging areas. The information provided on buoys is essential for mariners to navigate safely and avoid hazards such as dredging operations.

Dredging might be required in areas where sediment accumulates due to natural processes or human activities, and these areas are marked for safety and navigational purposes.
