A total of 131,815 macroinvertebrates were collected from meroplankton samples in the Savannah River and its tributary streams between 13 March and 29 August 1982. Fifty-three taxonomic groups, including 47 insect families and six non-insect taxa, were represented in the macroinvertebrate samples. Dipterans (true flies), particularly Chironomidae (midges) and Simuliidae (black flies) were the most abundant macroinvertebrate taxa at all transects. Other abundant taxa included Ephemeroptera (mayflies), Trichoptera (caddisflies), Amphipoda (scuds), Hydracarina (water mites) and nematode worms. When the invertebrate community was examined with respect to functional feeding groups, insect collectors were found to be the most abundant functional group. More invertebrate-taxa and higher densities of organisms were collected from the bottom drift samples than from the top of the water column, and more were collected from the center of the transects than from the bank areas. The results of the water quality analyses indicate that thermal discharges form Beaver Dam Creek, Four Mile Creek, and Pen Branch elevated the water temperature of the Savannah River approximately 1.6/sup 0/C between river Transects 6 and 9.
