Fishing Trinnsjön
perch, pike and zander sit at the top of the food chain in Trinnsjön, carried by roach. The clearer water makes the fish wary — and rewards a careful presentation.
Whoever fishes Trinnsjön regularly builds something of their own: a log of what took, where and when. That's how the water gives up its patterns — cast by cast, never all at once.
