Q. Is there a new law that requires all boat lifts, docks, swim rafts to be out of the water for 21 days before placing it in another water body?
A. Yes, the law became effective on July 1, 2012 and says, “A boat lift, dock, swim raft, or associated equipment that has been removed from any water body may not be placed in another water body until a minimum of 21 days have passed”. This law applies to anyone who places this type of equipment into a water body, not solely Lake Service Providers.

Q. What are the drying requirements for Service Providers when moving boats and equipment?
A. There are different drying/waiting times required by law or recommended as best practices. The following table is a summary based on type of water (non-infested waters, infested waters not including zebra mussel (ZM) infestations, and zebra mussel infested waters). The Designated Infested Waters list and signs at the water access can tell you which lakes are infested.

Q. Can water-related equipment be placed on riparian (shoreland) property and returned to the same waterbody without decontamination to remove zebra mussels and other nonnative species?
A. Yes, the state law has exception that allows water-related equipment be placed on riparian property and returned to the same waterbody without decontamination. Under state law, moving the equipment from the water to the riparian property is technically not transporting the equipment.

In state law it says, “Transport does not include: ... (2) the movement of a nonnative species attached to water-related equipment or other water-related structures from a water of the state to the shore of riparian property on that water or the return of water-related equipment or structures from the shore into the same water of the state.”

State law also says, "Introduce" means to place, release, or allow the escape of a nonnative species into a free-living state. Introduce does not include: ... (2) the seasonal return of nonnative species attached to water-related equipment, such as a dock or boat lift, that has been stored on riparian property and directly returned to the same waters of the state from which the water-related equipment was removed.

Q. Can water-related equipment be moved to and from the riparian property via road without decontamination in situations where the shoreline is not conducive (e.g., steep shore, retaining wall) to placing the equipment near the shore?
A. Yes, but only in the case of movement to riparian/shoreland property. The law exempts movement to and from riparian/shoreland property from the definition of transport.
