Twenty-seven fish species were collected from Conowingo Creek at eleven stations during the summer, 1970. Species most abundant were Rhinichthys atratulus, Notropis cornutus, Exoglossum maxillingua, Semotilus atromaculatus and Catostomus commersoni. A Spearman’s rank correlation coefficient matrix was calculated for biological and physical parameters. Distribution of fishes appeared related to width and depth of the stream, but was most influenced by gradient.
