Character of the water

The surroundings
The lake sits close to town with a road right up to it — easy to reach, but hard-fished and exposed to nutrient runoff from the buildings and fields all around.
Moderately deep (6 m) — shallow bays, the odd reef and a deeper channel through the middle.

Fishing Kotjärnen
perch, pike and zander sit at the top of the food chain in Kotjärnen, carried by roach. The clearer water makes the fish wary — and rewards a careful presentation.
Whoever fishes Kotjärnen 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.
