State law requires that scuba divers or snorkelers display a flag
to mark the diving area. Vessels not engaged in diving operations
must remain at least 100 feet away from areas displaying a diver-down
flag. Two types of flags are used to indicate diving activity.

Types of Flags |
|
Divers Flag: A rectangular red flag with a white diagonal
stripe must be displayed from a float during diving operations if on
state waters |
|
Alfa Flag: A blue and white International Code Flag A (or Alfa flag) must be displayed from boats during dive operations if the boats are restricted in their ability to maneuver. This flag indicates that the vessel is involved in a diving activity. |
Scuba divers and snorkelers should not place a flag in an area
already occupied by other boaters or where their diving operation
will impede the normal flow of waterway traffic. Divers also should
follow all of the water safety rules themselves.
Permits are required for some events and activities.
Many waterways in Pennsylvania have special regulations such as
horsepower restrictions. To check out a waterway’s specific
regulations, visit PFBC’s
