Indiana Dunes National Park Releases Over 1,600 Native Mussels into Little Calumet River

Indiana Dunes National Park recently placed more than 1,600 native fatmucket mussels (Lampsilis siliquoidea) into the East Branch of the Little Calumet River. The release is part of a water‑quality initiative aimed at improving the river’s health. The added mussels filter water and support a healthier ecosystem, which can benefit wildlife and hunting habitats downstream.
