This study conducted between September 2006 and July 2007 determined the present population status of unionids in the Brazos, San Antonio, and Lower Sabine River basins. Qualitative and Semi-quantitative sampling methods were used to conduct our survey. Abiotic parameters (pH, dissolved oxygen, turbidity, water temperature, water velocity, depth, TDS and substrate type) were recorded for each location and site. Thirteen species were found in the Brazos River Basin, 4 species in the San Antonio River Basin, and 1 species in the Sabine River Basin. Water turbidity and velocity at 60% of depth were significantly associated (Beta=0.645; p
