Duck River Basin, Tennessee, stations collected by A. E. Ortmann in 1921, 1922, and 1923 were revisited and collections made in 1965. Plethobasus cooperianus found at Columbia, Tennessee, on the Duck River is the only new record, but many new distributional records are reported for individual stations on Duck River. Nine new records are reported for Buffalo River. Forty-eight species were collected, as compared with the 63 reported by Ortmann. This is a 24% reduction in number of mussel species in Duck River, Tennessee, since Ortmann's 1924 report. General habitat has not been altered appreciably since 1924; however, municipal and industrial water use can be correlated with mussel decline in some areas. Corbicula manillensis has a wide range in the Duck River Basin and was found at 10 stations on the Duck River between Duck River miles 71 and 242.5.
