"We've done nine of them around the so state this year. And we're running a 26 percent violation rate. That means one out of every four boats coming into these check stations, are in viotion of one of our AIS laws, our aquatic invasive species laws. The most common violation we're seeing is failing to remove the drain plug," he said.

Salo said drain plugs have to be removed while watercraft are being transported.

Enforcement officers have written 169 tickets this season, and that the fines can run more than $100 per incident, he said.
