Leaping from pool to pool, salmon work their way up the fish ladder
toward spawning beds in the upper reaches of fresh-water streams.
Fish ladders enable salmon - and other fish that live in the sea, but spawn in rivers - to get past the dams.
Modern dams also make use of fish bypass structures. Migrating fish are routed around the dams's turbines to minimize danger.
