Lasse Pauhe and Kimmo Puosi are back on the banks of the Torne River in Svanstein, Lapland for this episode of The River duel, fly fishing for big Finnish Salmon. Before the duo begin their competition, they visit the sonic Salmon counter near the Korpiksoki Dam. Here they witness some of the 100,000 Salmon that run the river each year, some of which reach close to 1.5 metres long! Encouraged by their findings, Lasse and Kimmo decided to fish directly upstream of the counter in the Korpiksoki rapids, this time ditching the usual lure trolling for a traditional fly fishing approach from the bank.
