Ben's research describes benthic macroinvertebrate (BMI) communities in perennially and seasonally inundated habitats on the Trinity River under varying inundation periods. In addition, Ben describes benthic community composition shift after a winter streambed scouring event. The hydrologic regime can play a large role in benthic community dynamics. Historically, high flows on the Trinity occurred in the late winter/ early spring. Today, flows on the Trinity River are regulated by the Lewiston Dam and as a result, there is little flow variability in the winter/spring months and high flows occur in the summer when water is released. The results of this research can help guide a better tailored flow regime to support juvenile salmonids which feed heavily on BMI’s.
