 To prevent the spread of zebra mussels throughout Missouri and North America - and to keep your own equipment from being fouled - please observe the following “clean boating” suggestions when transporting your boat from waterway to waterway.
Inspect:
 Thoroughly inspect your boat’s hull, drive unit, trim plates, trolling plates, prop guards, transducers, centerboards, rollers, axles, anchor, anchor rope and trailer. Scrape off and trash any suspected mussels, however small. Remove all water weeds hanging from the boat or trailer before leaving any water body.
Drain:
 Drain water from the motor, livewell, bilge and transom wells and any other water from your boat and equipment while on land before leaving any water body.
Dump:
 Trash leftover bait on land, away from water, before leaving any water body. Leftover live aquatic bait that has contacted infested waters should not be taken to uninfested waters.
Rinse:
 When you get home - before launching your boat into uninfested waters - thoroughly rinse and dry the hull, drive unit, livewells (and livewell pumping system), bilge, trailer, bait buckets, engine cooling system and other boat parts that got wet while in infested waters; use a hard spray from a garden hose.
If the boat was in infested waters for a long period of time, or if there are any  attached adult mussels, use hot (104 F) water or tow the boat through a do-it-yourself carwash and use the high pressure hot water to “de-mussel” the boat. Do not use chlorine bleach or other environmentally unsound washing solutions.
Dry:
Boats, motors and trailers should be allowed to dry thoroughly in the sun for at least five days before boating again.
In the Slip:
In infested waters, the best way to keep a hull mussel-free is to run the boat frequently (small juvenile mussels are quite soft and are scoured off the hull at high speeds).
Where to look for zebra mussels:
Boats
Bait bucket
Recreational watercraft
