In order to aid the public in the prevention of the spread of AIS, the MPRB has implemented a watercraft inspection program. Effective April 15, 2013 ALL boats, watercraft and watercraft equipment passing through the public boat launches on Lakes Calhoun, Harriet and Nokomis will require inspections for aquatic invasive species. Boats launched from the shoreline are not required to have an inspection. Boat launches will be closed when inspectors are not on site; be sure to check for current boat launch hours prior to your visit.
In addition to watercraft inspections, MPRB also implemented the following actions to prevent the spread of AIS:
- AIS education and outreach efforts
- Lake usage data collection at the launches
- Signage and additional trash receptacles to encourage proper bait disposal at launches, fishing docks, and high use shoreline fishing areas
- Early detection monitoring
- Staff education
- Developing an AIS Rapid Response Plan for future Board adoption
AIS Prevention in the Future
Park Board staff will continue to evaluate and improve its AIS prevention program from year to year. AIS Inspectors will be collecting data during inspections to continue to help inform decisions about future efforts.
Under Minnesota law, it is illegal to transport aquatic plants and animals as well as water, to and from water bodies. Failure to comply with Minnesota AIS regulations can result in fines up to $1,000.
Help Protect Your Waters
If you are a lake user do your part to prevent the transport of aquatic invasive species from one lake, river or creek to another. Protect Minnesota’s waters by following the state aquatic invasive species laws.
- Clean visible aquatic plants, zebra mussels and other prohibited species from watercraft, trailers, and equipment before transporting from any water access.
- Drain water from bilge, livewell, motor, ballast tanks, and portable bait containers before leaving water accesses or shoreline property.
- Keep drain plug out and water-draining devices open while transporting watercraft.
- Dump unwanted bait in the trash.
You May Not:
- Transport aquatic plants, water, or prohibited invasive species such as zebra mussels or Eurasian watermilfoil.
- Dump live bait into state waters, on shore, or on the ground.
- Launch, or attempt to place, watercraft, trailers or equipment with aquatic plants, zebra mussels, or prohibited invasive species into any state waters.
Additional Recommended Precautions:
- To remove or kill hard-to-see aquatic invasive species before moving to other water bodies the following is advised:
- Spray with high-pressure water and rinse with very hot water and/or
- Dry boats and water-related equipment for at least five days
- Report new sightings of aquatic invasive species. If you suspect a new infestation of an invasive plant or animal, save a specimen and report it to a local natural resource office.
