Clean, Drain, Dry | Aquatic Invasive Species Campaign

Because aquatic invasive species can have devastating effects in Oregon waterways, invasive species managers want to take all precautions to keep these organisms from entering into or traveling around our waters. These plants and animals can be difficult to differentiate from our native species, which is why the Oregon State Marine Board and Oregon Department of Fish and Wildlife have implemented a Clean, Drain, Dry approach to keeping boats free of any and all aquatic species when out of the water. 


How do you "Clean, Drain, Dry"?

  • Clean all aquatic plants, animals and mud from your boat, motor or trailer and discard in the trash.  Rinse, scrub or pressure wash, as appropriate away from storm drains, ditches or waterways. Lawns, gravel pads, or self-serve car washes are best. 
  • Drain your motor, live well, bilge and internal compartments on land before leaving the waterbody. For paddle boats, drain by inverting or tilting the craft, opening compartments and removing seats if necessary. Rinse or flush under flooring, at inflation chamber joints or other areas that can trap mud and debris. 
  • Dry your boat between uses if possible. Leave compartments open and sponge out standing water. Find a place that will allow the anchor line to dry.  

Also, empty your bait bucket on land before leaving the waterbody. Never release live bait into a waterbody, or release aquatic animals from one waterbody into another.

What's the Problem with Aquatic Invasive Species?

Aquatic invasive species—primarily plants & animals—can flourish in our waterways, choking out native plants that once grew there and clogging boat, hydropower, and irrigation infrastructure. Examples of these species include Zebra & Quagga mussels, Ludwigia, Water Hyacinth, and New Zealand mudsnails.
