Correct Information About Kayak Registration?

I was told by the lady at the Washington County Park Office that in order to take my kayak onto Cross Creek Lake, I must have it registered with the state ($10), and also have a county sticker ($10), even if I don't use the boat launch. Is this correct? She didn't sound very knowledgeable or confident about what she was saying, and there can't be any harm in asking...so...her I am. 

From the PFBC website:
 
LAUNCH PERMITS
Owners of unpowered boats (canoes, kayaks, rowboats, etc.) can launch their boats at PFBC lakes and access areas or Pennsylvania state parks if their boats display a PFBC launch use permit, OR boat registration, OR Pennsylvania State Parks launch permit or mooring permit. Pennsylvania State Parks recognizes PFBC boat registrations and launch permits. The Commission does NOT recognize launch permits from other states. A PFBC launch permit can be purchased online at the Commission’s website. An unpowered boat may have a registration OR launch permit, but is not required to have both.
 

For the record: The portion I C&Ped is in regard to the state only, so county regs. may tack on additional fees.  
 
That said, the Launch Permit should work in lieu of a registration, and it is preferable, for the simple fact that once you get a boat registered, it must always be registered from there on out.  Not so with the launch permit.

Hmmm, I'd be interested (in the OP's position) to talk to someone who knew what they were talking about.  I'd be surprised if whoever made that rule would specifically require a kayak to be registered as opposed to the launch permit, especially when the issuing agent says that they're synonymous for that type of craft.
 
Not saying it isn't true.  I've seen more ridiculous regs zealously enforced by stupid local govt., but I would be mildly surprised.

All boats motorized or non-motorized and multi-chambered float tubes, belly boats, framed pontoons , etc require a county launch sticker, regardless of where you launch at Cross Creek Lake.
 
As I understand the rule you must only purchase a non-motorized permit if you also plan to use state owned facilitities like State Parks, Fish and Boat Commission Lakes/Launches.
