There is a specific law pertaining to water-related equipment or docks, lifts, and swim rafts. “As of July 1, 2012, 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.” - Minnesota Statute 84D.10
Decontamination Stations
Watercraft decontamination is a FREE service provided by Douglas County and the MN DNR designed to reduce the risk of spreading AIS. Douglas County deploys 3 mobile decontamination units and operates 1 permanent decontamination station located at the Le Homme Dieu – Krueger’s Creek access. These stations are staffed by trained and certified Level II Watercraft Inspectors.
The decontamination process consists of three possible components: hand removal, hot water treatment, and high-pressure treatment. Microscopic organisms can be killed by 100-140° F hot water and residual water can be flushed out of the watercraft system. Attached zebra mussels or aquatic plants can be removed by hand or with high-pressure water. No chemicals are used during the hot water treatment in the decontamination process.
