Pennsylvania does not have a blank rule for these circumstances but has the option to regulate when marked.
§ 103.3. Restriction for special areas.
(a) Boats are limited to slow, no wake speed when within 100 feet of the shore line; docks; launching ramps; swimmers or downed skiers or other boat-towed watersports participants; persons wading in the water; anchored, moored, or drifting boats; floats, except for ski jumps and ski landing floats; or other areas so marked. This subsection does not apply in a zoned ski area or authorized ski return areas when those areas are found within the areas described in this subsection.
(b) Boats are prohibited within 100 feet of water siphons or intake towers, including associated service bridges and supporting piers where so marked.
(c) The Executive Director is authorized to take immediate action to post and mark waters, establish speed zones or otherwise when he determines that a hazard exists that may threaten the safety of persons or property, or both. The Executive Director will notify the Boating Advisory Board and the Commission of the action. Zoned areas, speed limits or other markings established under this authority shall be fully effective and enforceable in accordance with law.
58 Pa. Code § 103.4. Lookout.
58 Pa. Code § 103.5. Safe speed.

Subject: Vessel Speed Limits near bridges and other obstructions
Good afternoon everyone. We are trying to find out if any jurisdictions have a standardized distance requiring boaters to proceed at a specific speed for example 6 knots 100 yards from every bridge or similar obstruction in the waterway. We currently have a number of speed zones around specific bridges and we are tossing around the idea of maybe trying to standardize the minimum speed around them.
Thanks
