The report summarizes data from the first three years of a long-term monitoring program to establish baseline conditions in benthic communities on the upper Potomac River. Major sources of variation were considered in an effort to characterize the effect of two power plants on distribution and abundance of the benthos. Distinct changes occurred in benthic communities in the vicinity of power plant discharges. These included decreased abundances of dominant species and reduced occurrences of rare species. Impacts associated with power plants were most severe during summer months and during low flow years.
