ABSTRACT


Historical and recent biological data from the Bloody Run and Sny Magill watersheds in northeastern Iowa were reviewed. Data were evaluated to determine if the findings from a 1991 study were similar to results of a study completed in 1978. Although sampling sites, collection methods, and ambient conditions varied between studies, the taxa encountered in the current and the 1978 study were very similar, while the relative abundance and dominant taxa were generally different.
