The study assessed the biological health of Minnehaha Creek by looking at the health of macroinvertebrate communities, and compared the results to a biological assessment study conducted in 2003. Additionally, the study assessed the macroinvertebrates community in six streams in the upper watersheds of Lake Minnetonka: Classen Creek, Painter Creek, Gleason Lake Creek, Long Lake Creek, Six Mile Creek and Schutz Lake Creek. The results are summarized in the report.
