  10. Meeting Objectives • Update on prep for testing flow-ecology hypotheses • Additional river classification attributes • Flow-Ecology Hypothesis descriptions • Prep for October workshop

  11. River Classification for FEH Analyses • Size • Ecoregion • Seasonal flow • Stability • Other attributes might include • p/a of floodplain • Regulated • ??

  12. Flow-Ecology Hypotheses Descriptions • Objective: Describe the mechanisms that drive the ecological responses to flow alteration • Format: 1-2 pages based on the description on the hierarchy of species-guild-assemblage hypotheses with citations • Schedule: draft to Shannon and Mary by end of August

  13. Prep for October Workshop • Preliminary results presented on August 22 webinar • First draft of report due late September (?) • Comments/discussion at workshop about • Report • Use of regional FEH • Other?
