Miller, A. C. (1988). Mussel fauna associated with wing dams in Pool 7 of the Mississippi River. Journal of Freshwater Ecology. 4:299-302.

Twenty-three species of freshwater mussels (Mollusca: Unionidae) were collected by divers in May, 1987, at 32 sites on and between wing dams in Pool 7 of the upper Mississippi River. Five species (Amblema plicata, Obliquaria reflexa, Obovaria olivaria, Lampsilis ventricosa and Quadrula pustulosa) comprised 90% of the fauna and were found at 88 - 100% of the sites. Specimens of Actinoaias ligamentina, Plethobasus cyphyus, and Strophitus undulatus, last reported in 1930, and the endangered Lampsilis higginsi, last reported in 1966, were collected alive.
