A gravel habitat consisting of four gravel bars separated by pools was designed for possible placement in a river bendway at river mile 232.9 on the Tombigbee River below Columbus Lake near Columbus, Mississippi. The site is immediately downriver of a minimum-flow release structure in Columbus Dam that passes 200 cfs of surface water from Columbus Lake. The design of the artificially placed habitat was based in part on biological and physicochemical characteristics of an existing gravel bar in the Buttahatchie River and in part on the characteristics and constraints of the river bendway where it is to be placed. Technical literature and reports of previous studies on the Buttahatchie and Tombigbee Rivers were also utilized. Because of favorite physical, chemical, and biological characteristics of the incoming lake water and the physically diverse nature of the proposed habitat, a dense and diverse invertebrate fauna including many species of common and uncommon mussels would be expected to inhabit this area.
