Start taking your offshore boat offshore, where it won't stick out so much and draw this kind of attention.
If you go back to the lake, be prepared to be heavily scrutinized and alot of your time burned up by these folks.
On the "ticket"- there's nothing they can do. They can turn it over to the prosecutor for that jurisdiction, but they failed to summons you for destruction of public property so my guess is they'll get asked why if they do choose to pursue this. It's incumbent upon them to pursue you for damages. They can't just levy against you, they have to file suit seeking compensation for the damages. They may send you a letter requesting or even demanding reparation, but the only way to force you is through the court system. Obviously if they want paid, unless you have witnesses, you may be better off paying. They've obviously decided to pursue you without facts and if they push this and are painted into a corner, they'll likely lie.
