Spring Benthic Macroinvertebrate Data

SQI refers to Stream Quality Index, a score that takes into account the abundance of sensitive organisms found at a site. Scores above 48 are rated excellent, 33-48 good, 19-33 fair and <19 poor. Since season affects the populations of macroinvertebrates, scores are compared by season.
