Drain, Clean Dry is a must for boaters

Casper - Boaters visiting Miracle Mile and Pathfinder Reservoir need to remember to Clean, Drain, and Dry all gear and equipment.  Curly pondweed is an invasive plant that is easily transferred in mud or water.  It competes with native plants reducing plant diversity and forms a dense mat that impacts water-based recreation activities.  All it takes it one small fragment of this plant to start a new population if moved to a different water.  Curly pondweed has been found at both Miracle Mile and Pathfinder making it critical to follow the Clean, Drain, Dry protocol to prevent spreading curly pondweed to other waters. 

CLEAN all equipment and gear of plants, mud and debris. Never move a plant or animal from one location to another.

DRAIN all water from your gear and equipment. This includes all types of watercraft, waders, boots, clothing, buckets – anything that comes into contact with the water. Bilge, ballast, and livewell plugs must be pulled when leaving the water and remain out during transport.  All vegetation must be removed from watercraft upon leaving the water.

DRY everything thoroughly. In Wyoming, we recommend drying for 5 days in the summer, 18 days in the spring or fall, or 3 days at freezing temperatures.
