Description

This project seeks to augment an existing research and monitoring program (focused on ELJs) in two subbasins of the Upper Columbia by monitoring the juvenile salmonid behavioral response to habitat restoration actions, specifically those that activate off-channel areas in floodplains at high flows. We will quantify how salmonids use different habitat types within activated floodplains, what environmental factors describe the habitat requirements of various life stages and species, and measure Chinook fry densities and growth over time simultaneously in activated floodplains and unrestored reaches to specify the quality differences between restored and unrestored habitats. We will also classify floodplain designs, measure the number and sizes of disconnected pools over time, and identify the individual numbers, species, and life stages of stranded fish to provide information on how to minimize stranding in future floodplain reconnection efforts.

Project Benefit

Monitor how salmon behave in off-channel areas in floodplains during high flows. The purpose is to determine how to avoid stranding in future projects.
