 | | The ovate clubshell was historically distributed in the Tombigbee, Black Warrior, Alabama, Cahaba, and Coosa Rivers and their tributaries in Mississippi, Alabama, Georgia, and Tennessee; and in Chewacla, Uphapee and Opintlocco Creeks in the Tallapoosa River drainage, Alabama. |
 | | With the exception of the dark pigtoe, which is believed to be naturally restricted to streams and rivers in the Black Warrior drainage, these mussel species were once widespread in the Basin, found in a continuum of small streams to large rivers in 2 or more major drainages. |
 | | Free-flowing river segments and their tributaries peripheral to the known historic range of the 11 mussels, and without any records of the species also cannot be considered to be essential to the conservation of these species (e.g., Mobile/Tensas River, lower Tombigbee River, etc.) and so were not considered further. |
