Historic records were used to identify areas within Illinois where spring cavefish (Forbesichthys agassizii), Ozark minnow (Notropis nubilus) and large scale stoneroller (Campostoma oligolepis) may be extirpated or overlooked by ongoing collection efforts. Several survey locations were selected for each species with the objective of determining species presence. Spring cavefish were collected at several sites throughout its historic distribution indicating continued persistence of this species. No Ozark minnow or large scale stoneroller were recorded, which suggests extirpation from or greatly reduced abundance in some parts of their historic distributions. This study supports the need for targeted surveys as a valuable information supplement for species that might otherwise be missed or under sampled by existing fisheries collection programs.
