Three freshwater mussel species under review for federal listing as threatened or endangered have historically been found in the San Antonio River Basin. One species, Golden Orb, has been recently found in numerous locations in the San Antonio River. In an effort to determine mussel densities and species richness for the entire native mussel community in the San Antonio River Basin (SARB), the San Antonio River Authority (River Authority) will be conducting reconnaissance surveys and mussel sample collections efforts throughout the basin. Data collected will be distributed to regulatory agencies to assist in decision-making process for at risk candidate species. Sampling locations include San Antonio River, Cibolo Creek, Salado Creek, Lower Leon Creek, Salatrillo and Martinez Creeks, lower Medina River, Medio Creek and West Side Creeks.
