The surroundings

Large and deep (25 m): a central basin ringed by drop-offs and shallow bays around the edges — varied bottom with many spots to read.

Fishing Fatsjön
perch and pike sit at the top of the food chain in Fatsjön, carried by roach. The clearer water makes the fish wary — and rewards a careful presentation.
Whoever fishes Fatsjön 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.
General rules of thumb for this kind of water
- In deep, oxygenated lakes the predators seek cool depth in summer, shallower in spring and autumn.
