Aquatic oligochaeta were qualitatively sampled from 10 stations on the Sandusky River between 26 October 1973 and 21 September 1974. Grab water samples were collected and analyzed for 15 parameters at the same stations. Eighteen species were collected with Branchiura sowerbyi, Limnodrilus cervic, L. hojjmeisteri, L. spiralis, L. udekemianus and Tubifex tubifex comprising 97.8% of the total identified fauna. Species composition and seasonal abundance differed in 3 distinct regions of the river, and the most oligochaetes/m2 were collected in July and the least in May. Three sewage treatment plants seemed to have an impact on the number of species and mean number of individuals collected below their outfalls. Species diversity was determined at all stations and was significantly correlated (P<0.5) with 13 of the 15 physico-chemical parameters.
