The relationship of water chemistry and habitat stressors with selected biological metrics and indices was determined in a watershed using two different river segmentation scales. Results show that the scale used for data aggregation affects the correlation between stressors and the biology. This study showed that habitat appears to be a more important factor than chemistry when large stream segments are used to aggregate data.
