Macroinvertebrate and water chemistry samples were taken at seven stations in the Yellowstone River between August 1973 and August 1974. The stations were located between Gardiner and Laurel, Montana. Macroinvertebrate samples were collected on six, and water chemistry samples on eight occasions, at 1-2 month intervals, throughout the year. The chemical analyses data show no water quality degradation; all concentrations were well below levels considered to be harmful to aquatic organisms. The observed differences in the macroinvertebrate community are believed to be attributable to ecological factors other than water chemistry.
