Forty six species of native freshwater mussels live within the refuge waters on the Ohio River. This includes five federally endangered mussel species: fanshell, pink mucket, sheepnose, northern riffleshell, and clubshell. Mussels are important to the health of a river ecosystem. They are filter feeders, which helps reduce silt, sediment, and pollutants in the water.
