The annual migration of young rainbow trout from the Henry’s Fork into the Buffalo River has been in full swing since mid-September. As of November 8, a total of 3,518 fish have migrated upstream through the Buffalo River fish ladder. The majority of these fish have been wild rainbow trout, including 1,618 fish smaller than six inches in length-those that are just entering their first winter.

To track winter survival of these small fish, HFF staff, interns, and volunteers have implanted each one of them with a tiny “bar code” tag that will be scanned by an electronic reader when the fish migrate back down to the river in the spring.
