Long-Term Benthic Monitoring Studies in the Freshwater Portion of the Potomac River - First Annual Report. Volume 2. Tables and Figures

摘要

The report summarizes the results of the first year of a long-term study of the benthic macroinvertebrate fauna of the freshwater portion of the Potomac River extending from Dam No. 5 near Williamsport, Maryland downstream to Seneca Pool near Seneca, Maryland. The primary objective of the study was to evaluate long-term trends in the distribution, abundance, and biomass of benthic macroinvertebrates and identify factors controlling the benthic populations, with particular emphasis on factors associated with existing power plant effluents within the study area.
