Biological and physical data were collected from main-stem habitats on the Missouri River between river between miles 661 and 678 during 1983. Sampling was conducted to describe water quality and fish and benthic macroinvertebrate populations associated with dike, revetment, and abandoned channels and those in the main river, indicating a well-mixed system. Revetted bank samples were dominated by larger species, such as the blue sucker and flathead catfish. The dike field had a similar assemblage of larger species with blue sucker, channel catfish, flathead catfish, and goldeye predominating. Overall abundance of fish larvae in the abandoned channels was much higher than in the main channel. There were differences in the densities and taxonomic composition of the benthic invertebrate communities in the different habitats.
