Summary:Abstract This study examined the invertebrate fauna from three deep wells located at the Uvalde National Fish Hatchery in south-central Texas. These wells provide a water source from geological strata of the southern boundary of the Edwards Aquifer ranging in age from Lower Cretaceous to Recent. Forty-seven collections, sampled on a continuous basis from November 2020 to January 2022, produced a total of 738 specimens comprising 15 different species. These collections reveal a diverse crustacean assemblage along with dominant numbers of the stygobiotic snail Balconorbis uvaldensis. This study provides a preliminary survey for future investigations of unidentified crustacean species as well as revealing seasonal variations in the reproductive life cycle of Balconorbis uvaldensis.
