Boaters can have courtesy decontaminations done at dozens of locations around the state. The decontamination units and DNR-authorized watercraft inspectors can help you comply with invasive species laws and reduce the risk of spreading aquatic invasive species.
The map shows some scheduled decontamination locations. The calendar feature searches availability on specific days. Additional dates will be added as the season progresses. If you are unable to find a convenient decontamination location, please contact your local regional watercraft inspection supervisor for alternatives.
