This report summarizes the key causes, or "stressors," contributing to impaired fish and aquatic macroinvertebrate communities of Mud Creek, a tributary stream to the Snake River located in east central Minnesota. Initially, a comprehensive review of existing biological, chemical, and physical data was performed to create a broad list of candidate causes for these impairments. The initial list of candidate causes was narrowed down after additional data analysis, leaving five candidate causes for the final analysis summarized in this report. The candidate causes evaluated in this report are listed below, along with a brief summary of their impact in this watershed.
