|Swimming is prohibited at Pennsylvania Fish & Boat Commission lakes and access areas. Boaters should keep a sharp lookout for swimmers and divers at all times.
A diver down flag is displayed from a float during diving operations. This flag is red with a white diagonal stripe running from the top of the staff to the opposite lower corner.
The code flag alpha is a blue and white pennant and boats must display this flag during dive operations if they are restricted in their ability to maneuver. Boats not engaged in diving operations shall remain at least 100 feet from areas displaying the diver down flag, or boats displaying the code flag alpha.
