Unionid mussels are the most imperiled taxa in the United States and are vastly understudied. The entire Robert C. Byrd (RCB) pool of the Ohio River is the study area. I selected sites from the 2019 and 2013 ORSANCO RCB pool assessments that utilize random site selection across the pool. I used SCUBA to survey and collect data on unionid diversity, reproduction, and habitat. I collected 1,083 individuals over 19 species in RCB pool. I compared results from RCB pool survey to two similar surveys conducted in Greenup Pool. Both richness and abundance in the Upper Section of Greenup Pool dwarfed all other sections in Greenup and RCB. Patterns of species redundancy are determined utilizing Nonmetric Multidimensional Scaling. RCB and Greenup Pool patterns are statistically similar. Data collected could serve as a baseline to site-specific surveys and have management implications for unionid assemblages in pools of large, navigable rivers.
