Abstract
We used a Scanning Hydrographic Operational Airborne LiDAR (Light Detection and Ranging) Survey (SHOALS) system to collect high-resolution bathymetry for 33 km of the Hanford Reach. Data were used in conjunction with hydrodynamic and predictive habitat models within a GIS (Geographical Information System) framework to evaluate the effects of a varying hydrograph on juvenile fall Chinook salmon rearing habitat and risk from stranding and entrapment. Furthermore, we were able to estimate the number of juvenile fish that were stranded and entrapped in pools when operations at Priest Rapids Dam caused rapid decreases in river flows. Our findings were ultimately used to estimate impacts of power generation operations at Priest Rapids Dam and develop long-term policy and operational guidelines to protect juvenile fall Chinook salmon during the spring rearing period.
