Decontamination Stations

Text/HTML

By law, all motorists hauling motorized or nonmotorized watercraft – including rafts, drift boats, canoes and kayaks – must stop. It’s the law.

You must stop at every inspection station you encounter—even if your boat was inspected that day. Subsequent stops will be brief but you must stop.
