Minnesota’s Clean, Drain, Dispose Laws (page 9 in Fishing handbook)

  • It is illegal to transport prohibited invasive species- whether dead or alive.

 Drain water-related equipment (boat, ballast tanks, portable bait container, motor) and drain bilge, livewell and baitwell by removing drain plugs before leaving any water access or shoreland property. Zebra mussel young are microscopic and can be transported through water.

  • Keep drain plugs out and water-draining devices open while transporting watercraft.

 Dispose of unwanted bait, including minnows, leeches, and worms, in the trash.conservationonaboat
