A migrating salmon faces a powerful waterfall on its journey upstream, but one enormous leap isn’t always the only route.
After being pushed back by the rushing water, it follows a smaller current running beside the falls.
The narrow passage leads through a series of calmer, stepped pools, allowing the salmon to progress upstream in shorter, more manageable bursts.
Eventually, the fish reaches the quieter water above the falls and continues its migration—a striking example of how flowing side channels and suitable passage routes can help fish move through challenging river habitats.
