Michigan’s 10th Congressional District comprises the Thumb region of the state. More than half of the district’s perimeter is shoreline on Lake Huron, Lake St. Clair, and the St. Clair River. The communities here are intimately tied to the Great Lakes, both reaping the benefits and feeling the impacts of life where the land meets the water.

  • The City of Caseville draws drinking water from Saginaw Bay, which can be affected by harmful algal blooms (HABs) and hypoxia.
  • Ice conditions and water levels influence decision-making and commerce in the district’s key ports, including St. Clair, Marysville, Marine City, and Harbor Beach.
  • Coastal communities feel the economic impact of invasive species like zebra and quagga mussels in Lake Huron, and cannot afford further losses from a potential Asian carp invasion.
  • With over 1.5 million acres of land in production and 17% of the state’s agricultural sales, Michigan’s 10th District can utilize agricultural decision support tools that benefit both farmers and Lake Huron.
