Powderhorn Lake Connectivity Project

Powderhorn Lake is part of one of the few remaining examples of the dune and swale topography – sandy ridges interspersed with water pockets – that once characterized the Calumet Region along the south shore of Lake Michigan. The area is home to 100 bird species, 250 plant species and 2,500 insect species. In addition to reconnecting water flow to Lake Michigan, this project will allow fish passage between the lakes, install water control structures to help prevent future community flooding, and increase hemi-marsh habitat. This work aligns with the Great Lakes Restoration Initiative objective of protecting and restoring communities of native aquatic and terrestrial species important to the Great Lakes.
