Abstract
The benthic macroinvertebrates of the Upper Iowa River basin in extreme northeastern Iowa were sampled in late April and mid July 1980. There were distinct population trends and differences between the April and July samples and also between the 14 mainstream and the 6 tributary stations. The benthic macroinvertebrates in and immediately downstream from Decorah indicated severe water quality degradation. The problem was limited, as the expected composition returned only a few kilometers downstream. A total of 149 taxa were collected.
