Champlain smallmouth stay hot as salmon slide deep

What's biting

What's next

With surface temps holding at 74°F, expect the next 2-3 days to stay in the same warmwater regime unless a cold front moves through. Smallmouth should continue to relate to deeper structure, humps, and drop-offs during the heat of the day, with the best windows likely at dawn and dusk when fish push shallower to feed. The late-summer momentum noted in the Bass Federation tournament results (per The Fisherman — New England Freshwater) suggests the smallmouth population is healthy and active right now — anglers who found fish over the August 8-9 weekend should expect that pattern to hold into the coming week if temps stay steady.

Landlocked salmon are the wildcard. At 74°F on the surface, salmon have almost certainly settled into cooler water below the thermocline, which typically means downrigger or lead-core trolling gets more looks than casting or shallow presentations. If overnight lows start dropping and the lake begins to turn over even slightly, expect salmon to become more catchable on standard trolling spreads as they follow baitfish that respond to the temperature shift. Until then, salmon action should be considered a slower, more technical bite that rewards anglers targeting depth rather than structure.

For timing, the waxing gibbous moon this week means brighter overnight light, which can extend low-light feeding windows into the early morning and late evening for smallmouth — worth planning a dawn push or a last-light session around structure rather than fishing the harsh midday sun. Weekend anglers should treat early morning as the priority window given the current thermal profile, since afternoon heat is likely to push smallmouth tighter to deeper cover and slow the bite until temperatures ease in the evening. No flow reading came through from gauge 04294500 this cycle, so there's no clear signal on current or inflow changes that could shift baitfish position — worth rechecking before a trip. Overall, expect a continuation of the current pattern rather than a dramatic shift over the next few days, with the smallmouth bite as the more reliable target and salmon requiring more patience and depth to connect.

Context

Late August on Lake Champlain typically finds smallmouth bass in a stable, structure-oriented summer pattern, which lines up with what came through this cycle — a Bass Federation tournament report (via The Fisherman — New England Freshwater) showing a winning non-boater bag over 30 pounds from the August 8-9 weekend, a solid showing that suggests the population is performing at or above typical seasonal expectations rather than lagging. Landlocked salmon, meanwhile, are exactly where the calendar says they should be: at 74°F surface temp, that species is almost certainly holding deep below the thermocline, which is standard for Champlain in high summer rather than any kind of late or early shift.

There's no direct salmon intel in this cycle's feeds to compare against a typical year, so it's honest to say that piece of the picture is thin right now — the temperature reading tells us where the fish likely are, but no shop, charter, or agency source weighed in on actual salmon catches or techniques for Champlain specifically this week. The smallmouth signal is the stronger of the two, grounded in a real tournament result rather than general seasonal assumption. Anglers planning a trip should lean on the smallmouth pattern as the more confirmed bite and treat salmon fishing as a standard late-summer deep-water game until more direct reporting comes in.
