Administrative Rule Change: All docks, lifts, and related equipment must be dried and left out of the water for at least 21 days before they may be placed in another water.

Boat docks and lifts are high risk structures for spreading aquatic nuisance species. They provide excellent habitat for zebra mussels and other ANS that can survive out of water for weeks. It can be difficult and sometimes impossible to find and remove every organism on a dock/lift. Therefore, a three week drying period is needed to prevent ANS introductions to new waterbodies.

ANS Spread Prevention Tips

  • Inspect your boat, trailer, motor, and other recreational equipment, including your water sports gear, waders, and anchor.
  • Remove all plants, animals, and mud from your equipment.
  • Drain all water from your livewells, ballast tanks, engine, and remember to pull all plugs that may hold back water during overland transport.
