Clean. Drain. Dry.
Protect our waters from aquatic invasive species
UMOWA encourages all floaters, boaters, and anglers to follow Montana Fish, Wildlife, and Parks invasive species laws and practice the #CleanDrainDry method.
The Three Steps
CLEAN
Remove all mud, water, and vegetation using a pressurized power sprayer with 120°F water before leaving the access area. No chemicals or soap required. Dispose of vegetation and debris in trash or on dry land.
DRAIN
Remove all water from watercraft and equipment before leaving the access area. This eliminates small, nearly invisible organisms that survive in standing water.
DRY
Thoroughly dry watercraft and fishing equipment using towels or sun exposure. Aquatic invaders survive only in water and wet areas.
Important Fact
Every piece of clothing can be a vector for invasive species transportation. The New Zealand mudsnail can attach to waders and boots and can be eliminated through heat exposure.


UMOWA and Missouri River Trout Shop installed Craig's first boat washing station to help prevent the spread of aquatic invasive species in the Missouri River watershed.
