Prickly Pear Creek, Montana, was sampled during four seasons in 1982 and 1983 to attempt to relate biological responses to fluctuations in discharge, in-stream toxicity and metal concentration in the water column. The biota (macroinvertebrate) were definitely impacted directly downstream from a metal source during all seasons, but no definite relationships among discharge, metal concentration and biological response could be established on a seasonal basis.
