Duluth, MN fishing report
Lake Superior and the Duluth harbor offer a genuine mixed bag depending on the season. Lake trout are available year-round in the cold, deep water off the breakwalls and along the rocky structure that drops sharply just outside the harbor mouth. Salmon — primarily coho and chinook — push into the harbor and nearby river mouths during fall staging runs, making late summer through October some of the most exciting fishing of the year. Walleye tend to concentrate in the harbor itself, especially near current breaks and the channel edges where warmer, shallower water meets the main lake.
For lake trout, work deep with jigging spoons or tube jigs tipped with a smelt strip when the thermocline drops in summer, targeting 80 to 150 feet. Salmon respond well to trolling spoons and stick baits along temperature breaks — watch for that 50 to 55 degree surface layer and fish the edges hard. Walleye in the harbor bite best at dawn and dusk; slow-roll a paddle-tail swimbait or drift a live shiner along deeper channel edges and near any structure that creates current seams. Dropping water temperatures in fall consistently trigger the best bites across all three species.
