Help stop the spread of Aquatic Invasive Species.

What are Aquatic Invasive Species?

Aquatic Invasive Species (AIS) are non-native plants and animals that tend to spread rapidly and outcompete resident species. AIS cause damage to the environment or economic loss. They include Zebra mussels, Eurasian watermilfoil, and Curly-leaf pondweed.

Protect Minnesota Lakes and Creeks

While there can be many ways of spreading these species, the most common include transporting them on boats, trailers, or boat lifts. Dumping leftover bait or unwanted aquarium plants and animals in lakes or creeks can also spread AIS.

Always follow state aquatic invasive species laws to protect Minnesota’s waterbodies:

  1. Clean your watercraft, trailer, and other water-related equipment of all visible zebra mussels, aquatic plants, and other prohibited invasive species before leaving any water access or shoreland.
  2. Drain water-related equipment and livewells before leaving a water access or shoreland. Keep drain plugs out during transportation.
  3. Dispose of all unwanted bait in the trash.

Adopt a Dock

If you live on a lake in the Nine Mile Creek Watershed District, consider participating in the Adopt a Dock program. Dock owners install a zebra mussel detection plate at the end of their dock, and check it once a month for zebra mussels. If you find a possible zebra mussel, District staff will come out to verify and pick up the sample, then report it to the Minnesota Department of Natural Resources.

Any lakeshore owners who are interested in participating are encouraged to contact Gael Zembal: 952-204-9691 or gzembal@ninemilecreek.org.

AIS Early Detectors Training

Are you involved in a lake group that wants to take action? In this training, lake groups learn to conduct monitoring for AIS, with a focus on early detection of species not already widespread in Hennepin County. Volunteers are trained and equipped so that a lake is periodically monitored for AIS. Any new species found can be detected early and better eradicated or managed. For more information, contact Gael Zembal: 952-204-9691 or gzembal@ninemilecreek.org.

What is the watershed district doing?

Monitoring and Management

Nine Mile Creek is monitored yearly by the District and the lakes are monitored on a rotating basis. Lake and creek monitoring data are summarized yearly in our Annual Reports, including any AIS information.

Education

Education is an important tool in stopping the spread of AIS. The District partnered with the City of Bloomington and local artists to create a Popup Education Cart with staff led hands-on activities that teach about AIS prevention. Find a Popup event, and come check out the fun!
