Movement and habitat shift responses of juvenile Atlantic Salmon (<scp> Salmo salar </scp>) to annually permanent stream flooding
Abstract Reservoir formation in a river system changes a lotic environment to more lacustrine conditions, with impacts throughout the ecosystem. In this study, a river reach containing typical salmonid riffle/run habitat was flooded to create a large, deep pool from June to September in each of 3 ye...

Abstract Reservoir formation in a river system changes a lotic environment to more lacustrine conditions, with impacts throughout the ecosystem.
