The purpose of this study is to evaluate the influence of physical factors, including sediment transport processes, on three aquatic species of concern. These species are steelhead trout (Oncorhynchus mykiss), Chinook salmon (Oncorhynchus tshawytscha), and California freshwater shrimp (Syncaris pacifica). The objective is to assess which factors are most likely limiting the success and size of sensitive aquatic species populations during the freshwater portion of their life cycle. In reporting our results, we place the greatest emphasis on factors limiting steelhead trout, the most ubiquitous of the three species throughout the watershed and an excellent indicator of overall aquatic ecological health. A goal of this study is to identify a range of possible restoration measures. The aim is to bring the best science possible to bear on framing a community-supported and cost-effective approach to the ecological recovery of Sonoma Creek.
