Bodensee (Lake Constance) fishing report
Updated Friday, 9 October 2026 · refreshed automatically through the day
A vast alpine lake shared with Austria and Switzerland. Whitefish are the bread-and-butter, "Kretzer" perch a local obsession, and the weed edges off river mouths hide serious pike.
Species and season on Bodensee (Lake Constance)
Whitefish (Felchen) are the lake's economic and angling backbone, perch (Kretzer) are fished almost year-round and are a local passion, and pike hold on the weed edges off the river mouths. Spring and autumn are the most productive for perch and pike; whitefish fishing is a deeper-water, boat-based craft.
How to fish it
A lake this size is read by depth, wind and temperature: whitefish follow the thermocline, perch work the drop-offs and harbours, and pike sit where reed fringes meet deeper water. Falling pressure ahead of a front often improves perch and pike activity; a cold northeast wind tends to shut the shallows down.
Access, licences and local rules
The lake is shared by Germany, Austria and Switzerland, and the rules differ by country and by lake section — the open Obersee, the Untersee and the Überlinger See each have their own regulations. In Germany you generally need a Fischereischein and a permit for the section, with a limited tourist licence available; Austria and Switzerland have separate cantonal and state systems. Confirm the rules for the exact stretch before launching a boat.
Rules, seasons and permit systems change. Treat this as orientation and confirm with the licensing authority or fishery manager before you fish.
