Character of the water

Stora Mörtsjön lies in central Sweden — a clear oligotrophic forest lake. The water is crystal-clear and the fish skittish in the sharp light.

The surroundings

The lake lies remote, ringed by forest and bog far from any road. Few find their way here — the water is untouched and the stock undisturbed.

Moderately deep (7 m) — shallow bays, the odd reef and a deeper channel through the middle.

Fishing Stora Mörtsjön

Stora Mörtsjön holds 10 species, with perch, pike and burbot at the top of the chain and ål, roach and regnbåge schooling beneath them. The modest depth keeps most of the fishing within reach of the bank.

The fishing here follows the water's own rhythm: dawn and dusk have their windows, fronts close and open them, and the season moves the fish. No two sessions at Stora Mörtsjön are alike.

General rules of thumb for this kind of water

Clear water makes fish light-shy — dawn, dusk and night are usually best.
