Enjoying a Great Lakes beach (Michigan Sea Grant)

The Great Lakes shoreline is home to many beautiful beaches that draw tourists and residents alike to the water's edge. In Ontario, the annual recreational value of Great Lakes beaches has been estimated at C$200-259 million,1 while U.S. Great Lakes beaches have been valued at US$1.1-1.4 billion.2

 

Mapping Great Lakes beaches

  • American beach locations were derived from the U.S. EPA BEACH Act Geospatial database. U.S. beaches were represented by line segments, which we converted to points using the midpoint of each segment.

  • The locations of Canadian beaches were provided by Environment Canada.

  • Asmall number of additional beaches were identified from protected lands databases for the U.S. and Canada.
