Aquatic Invasive Species (AIS) inspections are done May 1 – December 1 by DNR trained AIS inspectors during the following hours. The public boat launches are locked during non-launch hours.
Help Protect Your Waters
If you are a lake user please do your part to prevent the transport of AIS from one lake, river or creek to another. Protect Minnesota’s waters by following the state AIS laws.
MPRB’s Watercraft Education and Inspection Program
In April 2013 the MPRB implemented a Watercraft Education and Inspection program. All watercraft and water related equipment passing through boat launches at Lakes Harriet, Nokomis, and Bde Maka Ska are required to have inspections looking for aquatic invasive species (AIS). Boats launched from the shoreline are not required to have an inspection. Boat launches are 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, the MPRB also implements the following actions to prevent the spread of AIS:
- AIS education and outreach
- Boat launch 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 AIS detection monitoring
- Staff education
- Developed an AIS Rapid Response Plan
AIS Prevention in the Future
Park Board staff will continue to evaluate and improve its AIS prevention program from year to year. AIS inspectors collect data during inspections 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.
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, live well, motor, ballast tanks, and portable bait containers before leaving water accesses or shoreline property.
Dispose of unwanted bait in the trash or refill bait container with bottled or tap water.
Keep drain plug out and water-draining devices open while transporting watercraft.
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 watercraft and water-related equipment 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.
