Description Biological assessments were conducted to evaluate the health of aquatic habitat and to identify the principle stressors responsible for observed conditions in the Squalicum and Soos Creek watersheds. Biological communities, assessed using Benthic Index of Biotic Integrity (B-IBI) or River InVertebrate Prediction and Classification System (RIVPACS) scores, were found to be influenced by the multiple stressors of hydrology, water chemistry, and physical habitat. In both watersheds, biological monitoring and stressor identification confirmed that multiple stressors related to pollutant loading, embeddedness, and stream hydrology are the principle causes of impact. Stormwater runoff was identified as a common causal agent for both pollutant delivery and hydrological changes for these watersheds.
