Remember to Clean, Drain and Dry your watercraft to prevent the spread of aquatic invasive species.


  • Clean and inspect watercraft, trailer and gear
  • Remove all plants, animals, and mud at the access area or dock
  • At home, soak your gear in a bleach solution for at least one minute
  • Rinse, scrub or pressure wash your boat away from storm drains, ditches or waterways

Drain - Remember to pull the drain plug because it is now the law!

On land, before leaving the waterbody, drain all water from:

  • Bait buckets
  • Ballasts
  • Bilges
  • Coolers
  • Internal compartments
  • Livewells, etc.


  • Dry the watercraft and gear completely between trips and allow the wet areas of your boat to air dry
  • Leave compartments open and sponge out standing water.
