Zebra Mussels are an invasive species that arrived in the U.S. from Europe in the 1980s through the Great Lakes. They are native to Eurasia and have since spread to the Mississippi River and its connected waterways. They are small mollusks and have dark stripes on their shell. Zebra mussels destroy ecosystems in lakes and waterways by filtering algae that other species need for food and cling onto a variety of surfaces such as boats and docks. Zebra mussels have been parasitic to Crow Wing County’s lakes and waterways and continue to be a nuisance in the area and throughout the state. Using data collected from the Minnesota DNR for the years 2004 through 2018 we are able to map the expansion of zebra mussels throughout Crow Wing County. Excel was used to tabulate the data. The map created using ArcGIS helps visualize the extent to which zebra mussels have spread.
