Lake Trout Keep Biting on Lake Superior as North Shore Waters Swing

What's biting

What's next

North Shore surface temperatures should keep bouncing around over the next few days — the same wind-driven upwelling that dropped nearshore water to 41°F near Two Harbors on July 23 while Duluth stayed near 60°F offshore is a normal Lake Superior summer pattern, and southwest winds can flip that spread within a day or two, per the MN DNR Lake Superior Summer Fishing reports. Trollers should expect the thermocline bite to hold steady through the weekend: lake trout, coho, and chinook salmon have shown up on bright spoons, stick baits, and flasher flies fished 20-80 feet down over 100-150 feet of water on every DNR report since late June.

If the wildfire-smoke haze noted in the 7-16-26 DNR report continues to clear, expect better sight-fishing conditions and possibly stronger topwater activity for salmon as light penetration improves. Anglers working the lower shore between Duluth and Two Harbors should also budget extra time around the Highway 61 McQuade intersection and Lighthouse Point Road construction zones, which DNR reports have flagged as ongoing.

Inland, this week's Full Moon typically sharpens low-light walleye activity on Twin Cities-area lakes — worth planning an early-morning or dusk outing around it. Fishing the Midwest's recent notes on blending traditional live-bait presentations with forward-facing sonar suggest anglers who can locate suspended walleye schools should keep finding fish even as clear-water conditions make fish more selective. Largemouth bass anglers should stay on emerging vegetation with moving baits, a pattern the same source described producing consistent action.

No new smelt or steelhead activity is expected this time of year — that run wrapped up in the North Shore tributaries back in May — so summer trolling on Lake Superior itself and standard summer patterns on North Woods and Twin Cities lakes are the story through early August. Anglers should check state regulations before harvesting any species, since limits and seasons can vary by water.

Context

This summer's Lake Superior North Shore trolling season is tracking a fairly typical seasonal arc for the region. MN DNR North Shore Fishing Report editions from April through May show the spring steelhead run winding down and spawning activity tapering off in the tributaries as water levels dropped, followed by the smelt run — a normal handoff from spring stream fishing to summer open-water trolling. By late June, MN DNR Lake Superior Summer Fishing reports show lake trout, coho, and chinook numbers building steadily, with catch sizes creeping upward through July (lake trout in the 19-29 inch range in late June, up to 18-31 inches by mid-July) — consistent with typical summer growth and distribution patterns rather than anything unusual.

The wide surface-temperature swings reported this month, from upper-30s/low-40s nearshore to upper-60s offshore, are a normal feature of Lake Superior's wind-driven upwelling in summer rather than a departure from pattern, though the wildfire-smoke air-quality advisories noted in the July 16 report are a less typical seasonal wrinkle worth flagging for anglers planning visibility-dependent trips.

For Twin Cities and inland North Woods lakes, the available reporting doesn't include direct water-by-water intel this cycle. Fishing the Midwest's recent columns on forward-facing sonar and bait selection reflect broader technique trends shaping how Minnesota anglers approach summer walleye and bass fishing, rather than location-specific reports, so treat those as general seasonal guidance rather than a read on any particular lake.
